A regioregular organometallic polymer with titanacyclopentadiene unit, obtained by the reaction of a 2,7-diethynylfluorene derivative and a low-valent titanium complex, is subjected to the reaction with three kinds of electrophiles (i.e., sulfur monochloride, hydrochloric acid, and dichlorophenylphosphine) to give π-conjugated polymers possessing both fluorene and building blocks originated from the transformation of the titanacycles in the main chain. For example, a phosphole-containing polymer whose number-average molecular weight is estimated as 5000 is obtained in 50% yield. The obtained thiophene, butadiene, and phosphole-containing polymers exhibit efficient photoluminescence (PL) with emission colors of blue, green, and yellow, respectively. For example, the phosphole-containing polymer exhibits yellow PL with an emission maximum (Emax ) of 533 nm and a quantum yield (Φ) of 0.37.
一种具有钛杂环戊二烯单元的区域规整有机金属聚合物，通过2,7 - 二乙炔基芴衍生物与低价钛配合物反应制得，该聚合物与三种亲电试剂（即一氯化硫、盐酸和二氯苯基膦）反应，得到主链中同时含有芴和源自钛杂环转化的结构单元的π共轭聚合物。例如，以50%的产率得到数均分子量估计为5000的含磷杂环戊二烯聚合物。所得到的含噻吩、丁二烯和含磷杂环戊二烯的聚合物分别呈现出高效的光致发光（PL），发射颜色分别为蓝色、绿色和黄色。例如，含磷杂环戊二烯聚合物呈现黄色PL，发射最大值（Emax）为533 nm，量子产率（Φ）为0.37。
