摘要：
A symmetrical diarylethene containing N-salicylideneaniline (Schiff base) units was synthesized. The structure was well confirmed by NMR spectroscopy, mass spectrometry, and elemental analysis. Its photochromism was investigated by UV/Vis absorption spectra and NMR. The result displayed that diarylethene can well perform photoisomerization, but no obvious intramolecular proton transfer was observed. Furthermore, we checked the effects of metal cations for the properties of N-salicylideneaniline-based diarylethene, which indicated that Cu2+ and Fe3+ cations can significantly affect the UV/Vis absorption spectra of diarylethene ring-open and ring-closed isomers.

摘要：
A series of binuclear gold (I) complexes were synthesized. Their structures were characterized by elemental analyses, IR spectrometry, UV–Vis spectroscopy and single crystal X-ray diffraction. Their fluorescent mechanochromic (tribochromic) properties were investigated. The results of the mechanochromic studies suggested that the gold complexes with methylsubstituted phenyl bridges exhibited mechanochromism and a 100 nm red-shift of fluorescent spectrum could be observed after grinding. The complex with a diphenylmethane bridge exhibited mechanochromism with a change in fluorescence from green to blue (25 nm red-shift after grinding). The ground complexes reverted to their original states by treatment with CH2Cl2. No mechanochromism was observed for either the biphenyl or diphenylethane containing complexes.
摘要：
Four novel imidazole-based dithienylethenes have been successfully synthesized in good yields. Their structures have been confirmed by NMR spectrometry, mass spectrometry, and elemental analyses. UV/Vis absorption spectra indicated that these dithienylethenes can easily isomerize between the open-ring and closed-ring isomers upon irradiation with UV or visible light in solution, and that the respective closed-ring isomers show decreased fluorescence properties compared with the open-ring isomers. Moreover, the open-ring and closed-ring isomers display high selectivity toward Fe3+, such that the addition of Fe3+ obviously suppresses their fluorescence intensity.

摘要：
The dithia[3.3]paracyclophane-bridged bimetallic ruthenium alkynyl and vinyl complexes {Cp*(dppe)RuC≡C}2(μ-dithia[3.3]paracyclophane) (8) and {(PMe3)3(CO)ClRuCH═CH}2(μ-dithia[3.3]paracyclophane) (9) have been prepared and, in the case of 8, structurally characterized. Compounds 8 and 9 each undergo two consecutive one-electron-oxidation processes, with supporting investigations conducted using IR and UV/vis/near-IR spectroelectrochemical methods establishing the redox-noninnocent character of the dithia[3.3]paracyclophane bridge unit in both 8 and 9. Both [8]+ and [9]+ exhibit multiple transitions in the near-IR region, which have been assigned with the aid of DFT calculations to combinations of MLCT and intraligand transitions and transitions involving the donor sulfur atoms within the cyclophane scaffold to the partially occupied orbital located on the diethynyl- or divinylphenylene portion of the bridging cyclophane.

摘要：
A series of [2]catenanes were efficiently synthesized in high yields by a template-directed clipping approach with the formation of one macrocycle around another macrocycle containing a dialkylammonium recognition site. Their structures were identified by the NMR spectra and ESI mass spectrometry, and their geometries were investigated by the theoretical calculation.

摘要：
The construction of coronenes using simple building blocks is a challenging task. In this work, triphenylene was used as a building block to construct functionalized coronenes, and their solid structures and optoelectronic properties were investigated. The single crystal structures showed that coronenes have different packing motifs. Their good solubility and photostability make them potential solution-processable candidates for organic devices.
