Substituent and solvent effects on the fluorescent and photochromic properties of 2-(2-pyridyl)imidazole containing diarylethene derivatives was written by Peng, Xuefeng;Deng, Jian-Guo;Xu, Hai-Bing.

Five diarylethene derivatives with 2-(2-pyridyl)imidazole as the ethene bridges (PI-BTEs) were synthesized and characterized. The structures and performances of these PI-BTEs could be modified from not only the thiophene unit, but also the substituent on the imidazole nitrogen. Noteworthily, replacing the thiophene with the benzothiophene, the fatigue resistance is significantly improved, the center absorption bands of the closed forms shift from 572 nm (dithiophene derivative) to 550 nm (dibenzothiophene derivative) , and the colors of the solutions change from pale pink in dithiophene derivative to red-purple in dibenzothiophene derivative Addnl., the Stokes shift Δν values of dithiophene derivative in various solvents display good linear relationships with the donor number (DN) of the solvents, and the solvent polarity parameter Δf. In the experiment, the researchers used many compounds, for example, 3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9Related Products of 10243-15-9).
3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9) belongs to benzothiophene derivatives. Benzothiophene is a fused ring compound of thiophene ring and benzene ring, which is an important class of heterocycles with advantageous structures. It has been used as a raw material for the synthesis of biologically active structures and is found in pharmaceuticals such as leukotriene synthesis inhibitors and antifungals, as well as in many natural products.Related Products of 10243-15-9
