Optically Switchable Conductive Polymers
Abstract
The objectives of the project were to synthesize and characterize a polymer which could be switched to its conductive state by intramolecular electron transfer initiated by absorption of light. By covalently bonding the electron donating moiety to the polymer, the rate of switching should be fast and uniform giving it potential applications in optical processing devices. The initial polymer system selected was a polythiophene substituted at the 3 position with a diphenyliodonium salt. Photodissociation of diphenyliodonium chloride in physical contact with the polymer formed the highly oxidizing phenyliodonium radical cation which in turn oxidized the polythiophene backbone. Several approaches tried to synthesize the covalently bound substituted polythiophene were unsuccessful. Polymerization of 3-ferrocenylpyrrole, which also has potential photodoping properties, was also unsuccessful.
