The development of novel dithienylethene-based complexes is highly desirable for potential application in the photoresponsive optoelectronics. In this contribution, the authors designed and prepared four novel dithienylethene-containing isocyanides 9a–9d and their binuclear Au(I) complexes 3a–3d with various alkyl chains. They were fully characterized and confirmed by 1H NMR, 13C NMR, 19F NMR, and HRMS (ESI-TOF). Upon alternating irradiation with UV light at 302 nm and visible light at 530 nm, these isocyanides and corresponding Au(I) complexes displayed good photochromic behavior. And the slight effect of the length of alkyl chains on photochromic properties of these isocyanides and Au(I) complexes was observed Also, compared to the precursors 9a–9d, their Au(I) complexes 3a–3d showed higher molar absorptivities for ring-open isomers, closing rate and cycloreversion quantum yields. Au(I) complexes displayed much more excellent fatigue resistance compared with that of isocyanides. Accordingly, these results further proved the formation of Au(I) complexes can promote photochromic behavior to some extent.
