Two [thiopheneâ1,6-dithienylhexa-1,3,5-triene] copolymers were prepared by a palladium catalysed coupling reaction of a dibromothiophene derivative and a bis(tributylstannyl) derivative of a 1,6-dithienylhexa-1,3,5-triene unit. The electrochromism and the photoluminescence properties of the highly conjugated polymers were studied. In the solid state the polymers have strong photoluminescence bands at 2.0Â eV for 9 and 1.95Â eV for 8. Polymer 8 seems particularly promising for use as a red-light emitting diode, and the two polymers 8 and 9 exhibit redâpale blue electrochromism that makes them suitable for fabricating new devices.
通过二溴噻吩衍生物与 1,6-二噻吩基六-1,3,5-三烯单元的双(三丁基锡)衍生物的钯催化偶联反应,制备了两种[噻吩-1,6-二噻吩基六-1,3,5-三烯]共聚物。对这些高度共轭聚合物的电致变色和光致发光特性进行了研究。在固态下,9 号聚合物和 8 号聚合物在 2.0eV 和 1.95eV 处具有很强的光致发光带。聚合物 8 似乎特别有希望用作红光发光二极管,而两种聚合物 8 和 9 则表现出淡红蓝色电致变色特性,使它们适合制造新设备。
