Synthesis of precursors for photoconductive polymers

Abstract

Following our search for new organic materials with optoelectric properties, we perform the synthesis of a new acrylic monomer containing thiophenes as pendant groups. The inclusion of an aliphatic spacer was achieved by the formation of an imine from the heterocyclic aldehyde, while the introduction of the polymerizable function was carried out by an acylation reaction with acryloyl chloride. The tests for the inclusion of aliphatic spacers were very promising, mainly considering their application to other heterocycles of interest. In this work we present the results obtained in the synthesis of the monomer working with tertiophene-2-carbaldehyde and 3-aminopropanol as aliphatic spacer, precursor of the polymeric material of interest, and its characterization by 1H-NMR.This work was performed in colaboration with Prof. Dr. Martin Conda-Sheridan. Experimental task
were performed in his laboratorio of Nebraska Medical Center University – USA.
