Abstract
Electro-optic (EO) organic polymer films show great promise for integrated photonic device applications. Molecules used in these films must possess both large nonlinear optical coefficients and sufficient thermal stability to withstand the high temperatures required by the poling and device fabrication processes.1 Recent thermal gravimetric analysis experiments have shown that a new fused-ring guest molecule designed for in- corporation into host polyimides, 1,8-naphthoylene-(3′-pyrrolidino)-benzirnida-zole-4,5-dicarbox-N-(2,5-di-tert-butyl) phenylimide (hereafter SY215, shown in Fig. 1 along with its linear absorption spectrum), exhibits less than 5% weight loss until approximately 400°C in its pure form.2
