摘要：
A fluorescent calix[4]arene triazole-linked pyrene (CP) was carefully designed and synthesized via click chemistry. The modification of CP with graphene oxide (GO) by a simple non-covalent interaction strategy is presented. Further inspection by electrochemical impedance spectroscopy reveals that the CP-GO could exhibit a very high supramolecular recognition for carbaryl, in particular in serum samples with a nanomolar concentration detection. Additionally, it is easy to directly observe macroscopic recognition by the contact angle, and expand practical applications.

摘要：
Highly sensitive recognition of important chiral bioactive substances in complex biological fluids is a great challenge. An efficient chiral discrimination system for amino propanol enantiomers is reported based on R-mandelic acid calix[4]arene (FC4D) clicked graphene. Notably, taking advantages of both the functional calixarene and graphene, the proposed FC4D-G demonstrates extremely high sensitivity and selectivity toward the recognition of amino propanol enantiomers, with a detection limit at the nM level in a serum sample. More important, a visible macroscopic chirality-responsive wettability variation was also realized in this study. This journal is ©The Royal Society of Chemistry 2015.

摘要：
A new fluorescent dianthracene calix[4]arene (C4DA) was designed and synthesized via coupling the fluorescent anthracene units and calix[4]arene units. Then it was used to form self-assembled monolayers (C4DA-SAMs) by the simple click reaction to give the first fluorescent and wettable dual-signal switch for tryptophan (Trp) on a micro- and nano-structured silicon surface. The switch for Trp on the C4DA functional surface was confirmed by contact angle (CA) measurements and fluorescent spectroscopy (FL). Furthermore, the wettability-responsive C4DA functional interface can be re-used for six cycles. The responsive switch can potentially be applied in many fields including nanodevices and intelligent microfluidic switching.

摘要：
A novel series of calix[4]arene derivatives were synthesized via a Pd-catalyzed Sonogashira coupling reaction from para-substituted iodobenzene and 25,27-dipropargyl-calix[4]arene. Fluorescence studies found that nitro-phenols clearly exhibited quenching effects on 2c. Moreover, we minimized the free energy of the complexes by theoretical calculations. As the result, the π-π stacking interactions take place between the 4-nitrophenol and calix[4]arene, which may lead to the significant fluorescence quench. © 2013 De-Mei Tian.

摘要：
A photoreversible switch based on a photoresponsive host-guest system consisting of dimethylamino calix[4]arene L and 4-(phenylazo)benzoic acid (O) is reported. The host L exhibited selective binding and release of O on UV and visible irradiation at 450 and 365 nm, respectively. Moreover, the photoresponsive host-guest complex was applied as a photocontrolled wettability switch on a functional micro/nanostructured silicon surface, and is thus promising for applications in sensors and microfluidic devices. Photoreversible switching of the host-guest system of dimethylamino calix[4]arene (L) and 4-(phenylazo)benzoic acid (O) is reported. Host L exhibited selective binding and release of O under UV and visible irradiation at 450 and 365 nm, respectively. Moreover, the L⊃O complex was applied as a photocontrolled wettability switch on a functional micro/nanostructured silicon surface with reversible switching between hydrophilic and hydrophobic states (see figure). © 2014 WILEY-VCH Verlag GmbH & Co.

摘要：
Inspired from their biological counterparts, chemical modification of the interior surface of nanochannels with functional molecules may provide a highly efficient means to control ionic or molecular transport through nanochannels. Herein, we have designed and prepared a aldehyde calix[4]arene (C4AH), which was attached to the interior surface of a single nanochannel by using a click reaction, and that showed a high response for arginine (Arg). Furthermore, the nanofluidic sensing system has been challenged with complex matrices containing a high concentration of interfering sequences and serum. Based on this finding, we believe that the artificial nanochannel can be used for practical Arg-sensing devices, and be applied in a biological environment.

摘要：
4-Amino-3-mercaptobenzoic acid (AMBA) functionalized gold nanoparticles were synthesized through reduction reaction and the resulting gold nanoparticles were characterized by UV-vis spectroscopy, IR spectroscopy, and transmission electron microscopy (TEM). 4-Amino-3-mercaptobenzoic acid functionalized gold nanoparticles have a cooperative effect on recognition of cyhalothrin with distinct changes both in color and absorption properties over other pesticides tested. The detection system presents excellent anti-disturbance ability and can be applied to the determination of cyhalothrin in real different water samples such as Yangtze River water sample and East Lake water samples with the limit of colorimetric detection (LOD) of 0.75 mu M. Besides, a test strip, based on AMBA-functionalized gold nanoparticles for cyhalothrin detection, has been developed, optimized and validated. The developed colorimetric mercury sensor system exhibited a highly sensitive and selective response to cyhalothrin. (C) 2014 Elsevier B.V. All rights reserved.

摘要：
A novel piperidine-calix [4] arene was synthesized by the Mannich reaction. Then, piperidine-calix [4] arene modified gold nanoparticles (PPC-Au NPs) were designed and synthesized through click reaction. The resulting gold nanoparticles were characterized by UV-vis spectroscopy, IR spectroscopy, transmission electron microscopy (TEM). The newly synthesized gold nanoparticles had a cooperative effect on recognition of imidacloprid resulting in appreciable changes in color. The advantage of our experiments over classical assays is it can realize the prompt on-site and real-time detection of imidacloprid with high sensitivity (5.0 ×10<sup>-6</sup> M) and selectively. The developed method was also successfully applied for detecting imidacloprid in tape water with a detection limit of 2.5 ×10<sup>-5</sup> M. ©2014 Elsevier B.V. All rights reserved.

A series of novel 5-alkyl(aryl)-3-[(3-trifluoromethyl)anilino]-4,5-dihydro- 1H-pyrazolo[4,3-d]pyrimidin-4-imines were designed and synthesized by the multistep reactions. 1 reacted with 3-(trifluoromethyl)aniline to obtain N,S-acetals 2 in the presence of 10 mol% DBU. 2 reacted with hydrazine to form 5-amino-3-[(3-trifluoromethyl)anilino]-1H-pyrazol-4- nitrile 3, the target compounds 5a, 5b, 5c, 5d, 5e, 5f, 5g, 5h, 5i, 5j, 5k, 5l, 5m were obtained by the reaction of 3 with triethyl orthoformate followed by the cyclization of 4 with various amines. Their structures were confirmed by IR, 1H NMR, EI-MS, and elemental analyses. The preliminary bioassay indicated that some of them displayed moderate herbicidal activity against dicotyledonous weed Brassica campestris L at the concentration of 100 mg/L. For example, compounds 5f, 5g, 5h, and 5j possessed 60.1%, 63.4%, 67.1%, and 61.3% inhibition against Brassica campestris L at the concentration of 100 mg/L. © 2013 HeteroCorporation.

A novel strategy for the fabrication of a highly selective and sensitive imidacloprid probe based on imidazole ionic liquid (IL) modified gold nanoparticles (I-IL-Au NPs) was developed. The resulting gold nanoparticles were characterized by UV-vis spectroscopy, IR spectroscopy, transmission electron microscopy (TEM). The newly synthesized gold nanoparticles had a cooperative effect on recognition of imidacloprid in aqueous solution resulting in appreciable changes in color and absorption properties over other 13 pesticides tested. The advantage of our system over classical assays is that it can realize the prompt on-site and real-time detection of imidacloprid with high sensitivity (5 ×10<sup>-7</sup> M) in aqueous solution. Moreover, the detection system can be applied to the determination of imidacloprid in real different water samples such as the Yangtze River sample and East Lake water samples with the limit of colorimetric detection as low as 1.0 ×10 <sup>-5</sup> M and 1.0 ×10<sup>-6</sup> M. In addition, our detection system can realize relatively effective removal of imidacloprid. ©2013 Elsevier B.V. All rights reserved.
