π-Conjugated poly(1,10-phenanthroline-3,8-diyl), PPhen, and its 5,6-dialkoxy derivatives, PPhen(5,6-OR)s, have been synthesized by using an organometallic polycondensation with a zerovalent nickel complex. They had average molecular weights of 4300−6800. PPhen had a stiff structure, as revealed by a light scattering method, and exhibited a strong dichroism in UV−vis absorption and photoluminescence
π共轭聚(1,10-菲咯啉-3,8-二基)PPhen及其5,6-二烷氧基衍生物PPhen(5,6-OR)s是利用零价的有机金属缩聚反应合成的镍配合物。他们的平均分子量为4300-6800。如通过光散射法所揭示的那样,PPhen具有坚硬的结构,并且在UV-vis吸收和光致发光方面表现出很强的二色性。PPhen(5,6-OR)s通过OR基团的侧链结晶形成了一个端到端的组装组件。PPhen和PPhen(5,6-OR)s易于化学和电化学还原,并且还原态对空气中的氧气显示出一定的稳定性。π共轭聚合物与[Ru(bpy)2 ] 2+形成定量络合物。在PPhen的重复单元中再引入两个亚胺氮大大提高了PPhen的电子接受性能,所得聚合物的n-掺杂在相对于Ag + / Ag的E pc为-1.38 V下发生。
