ABSTRACT:
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.
