Electronic Properties of Ordered Ladder Polymers

Abstract

Experimental studies of the electronic and electrical properties of high temperature ordered ladder polymers, exemplified by benzimidazobenzophenanthroline type ladder polymer (BBL) and ladder polyhydroquinoxalines (PHQXL), are reported. In addition, this report presents results of studies on the structural, electrochemical, and mechanical properties of undoped insulting and doped chain and ladder polymers as well as a novel processing approach for the rigid chain an ladder polymers. The two types of ladder polymers investigated, BBL and PHQXL were found to be insulators in the undoped state. However, upon chemical, electrochemical, or ion implantation doping the room temperature electrical conductivity of films of these ladder polymers was enhanced up to 2-220/ohm/cm depending on the method of doping. Thus, high-temperature potential electronic and aerospace applications.
