摘要：

Polymethylphenylsilane (PMPS) was modified by chloromethylation then condensed with Na salt of Disperse Red 1(DR1). The product, DR1 functionlized PMPS(PMPS-DRD, was thoroughly washed until it had no DRl or other dopant. Its glass transition temperature is 155℃, contains 4.5% weight of DRl residue. The UV-Vis spectrum of PMPS-DRl shows a broad ab-sorption band in the range 400-700 nm. Photoconductivity measured on a 2 μm film made of PMPS-DR1, using a 632.8 nm He-Ne laser beam, shows that it is electric field dependent and in the range of 10-13 to 10-11S/cm. The electro-optical coefficient of PMPS-DRl was measured as a value of r33=0.8 pm/V.
