Development of Novel Photoconductive Liquid Crystals for Large Area Photodetectors

Abstract

Attempts were made to develop liquid crystals based on the Pd/Cu-mediated cyclization of o-iodo-trimethylethynylbenzenes. We found that the palladation of the triazene protected intermediate led to a stable organo-palladium complex, frustrating further reaction. An alternative route, using the dehydrofluorination of triazene functional trifluorostryenes led to the desired building block. Unfortunately, cyclization proved unsuccessful.
