Abstract
A new type of soluble calix[4]arene-based polyimides was prepared by r eaction of bis(3-aminopropyl) dipropyl functionalized tetranitrocalix[ 4]arenes with hexafluoroisopropylidene diphthalic anhydride. Spin-coat ing of these polymers and subsequent electric field poling results in films that are highly transparent above 410 nm and exhibit high and th ermally stable second harmonic generation coefficients. These properti es make these materials very suitable Ear frequency-doubling applicati ons in the UV region (820-410 nm).
