Photochromic Properties of Thiophene and Thiazole-Substituted Bicyclic Aziridine in Solution and Solid State.

ABSTRACT: Bicyclic aziridine (1,3-diazabicyclo[3.1.0]-hex-3-enes) has derivatives (DABH) known for their photochromic properties. A photochromic compound undergoes reversible isomerization between two states upon light irradiation. In the transition from the closed-ring to open-ring form, formal charges are generated in the more conjugated open-ring state. Thiophene and thiazole, known for their electron-rich nature and high charge mobility, were conjugated to a DABH substituent. We report the synthesis of DABH conjugated to thiophene (Th-DABH) and thiazole (Tz- DABH), both of which exhibit photochromic behaviors in the solution and the solid state. Optical absorbance measurements revealed a redshift in the maximum absorption wavelength λ_max from 437 to
