A series of new organic semiconducting copolymers composed of {(2E, 2'E)-3, 3'-[2, 5-bis (octyloxy)-1, 4-phenylene]-bis [2-(thiophen-2-yl) acrylonitrile]}(OPTAN) and 10 (2'- ethylhexylphenothiazine)(PTZ) monomers,(the copolymers are hereafter referred to as poly (OPTAN-co-PTZ) s), were synthesized by using Suzuki coupling polymerization in which the monomer ratios were controlled. An increase in the OPTAN content shifted the peak and ...
