A di-p-tolyldialkylsilane derivative, a photoluminescence polymer formed from the derivative, and methods for preparing the derivative and polymer are provided. The di-p-tolyldialkylsilane derivative is represented by the following formula (1): ##STR1## where R.sub.1 and R.sub.2 are independently selected from the group consisting of phenyl and --(CH.dbd.CH).sub.k R.sub.3 (k is an integer between and inclusive of 0 and 2, and R.sub.3 is hydrogen or alkyl), and X.sup.2 is selected from the group consisting of hydrogen, halogen atom and cyano group. The di-p-tolylalkylsilane derivative of the formula (1) is very useful as a monomer of a functional polymer. The photoluminescence polymer formed from the di-p-tolylalkylsilane derivative of the chemical formula (1) contains a repeating unit having a silicon between the conjugated double bonds, thereby suppressing electron movement of the conjugated double bond. As a result, a range of colors between blue and green, particularly, blue, can be obtained. Also, when the photoluminescence polymer is adopted as a color-developing substance, the threshold voltage characteristics are improved.
本发明提供了一种二对甲苯基二烷基硅烷衍生物、由该衍生物形成的发光聚合物以及制备该衍生物和聚合物的方法。该二对甲苯基二烷基硅烷衍生物由下式(1)表示:##STR1## 其中,R.sub.1和R.sub.2独立地选自苯基和--(CH.dbd.CH).sub.k R.sub.3(k是介于0和2之间的整数,R.sub.3是氢或烷基),X.sup.2选自氢、卤素原子和氰基。式(1)中的二对甲苯基烷基硅烷衍生物非常有用,可作为功能性聚合物的单体。由化学式(1)的二对甲苯基烷基硅烷衍生物形成的发光聚合物包含具有硅的重复单元,从而抑制了共轭双键的电子运动。因此,可以获得蓝色和绿色之间的一系列颜色,特别是蓝色。此外,当将发光聚合物作为着色剂时,阈值电压特性得到改善。
