Abstract

We report synthesis and properties of new phenothiazyl polymer derivatives, Poly(10-octyl-10Hphenothiazine-3,7-diyl)(POP), Poly(2',3',6',7'-tertrakis-octyloxy-9-spirobifluorene-2,7-diyl) (PTOSF), and their random copolymers, Poly(10-octylphenothiazine-co-2',3',6',7'-tertrakis-octyloxy-9-spirobifluorene) (POTOSF). PL emission of POP, PTOSF and POTOSF copolymer were found to be 480, 434 and 484nm, respectively. EL emission peak of double-layer EL device of POTOSF was at 494nm (bluish green).
