Photochromic oligothienoacene derivatives with photo-switchable luminescene properties and computational studies

Abstract

Photochromic thieno[3,2-b]thiophenes and dithieno[3,2-b:2′,3′-d]thiophene with photo-switchable luminescence properties have been synthesized using a Suzuki cross-coupling reaction; their electronic structures, and photochromic and luminescence behaviour have also been studied.
