End Group

We designed and synthesized ITIC5 by replacing benzene-fused end groups of ITIC1 with thiophene-fused end groups and investigated effects of thiophene/benzene-fused termini on optical and electronic potentials of these molecules as well as the performance of organic solar cells.

Isomeric Effect

A TT-terminal ladder-type donor is generally a better molecular design than the corresponding T-terminal ladder-type isomer for the development of new A–D–A NFEAs.
