Conductive heterocyclic ladder polymers

Abstract

Phenothiazine Ladder Polymer, PTL (or di-chloro-PTL) was prepared by polydensation of 2,5-diamino-1,4-benzenedithiol with 2,5-dichloro (or 2,3,5,6-tetrachloro)-p-benzoquinone in polyphosphoric acid at 250.degree. C. Phenoxazine Ladder Polymer, POL, was prepared from 2,5-dichloro-p-phenylenediamine and 2,5-dihydroxy-p-benezoquinone under the same conditions as used for PTL synthesis. Di-chloro-POL and other derivatives can be made under a similar condition. These polymers conduct electricity.
