Description

o-IDTBR demonstrates an acceptor-acceptor–donor–acceptor-acceptor (A-A'–D–A'-A) structure consisting of an electron-donating ladder-type fused five-member-ring indaceno[1,2-b:5,6-b′]dithiophene (IDT) core with aliphatic n-octyl side chains, flanked by two electron withdrawing benzothiadiazole moieties and rhodanine terminated groups.
