✦ Synopsis

Polymethacrylates and polyurethanes containing covalently bound organophosphorus NLO chromophores have been synthesized and characterized. These polymers contain a high concentration of NLO chromophores. Film samples obtained by spin coating and poled by the corona method show large second harmonic coefficients (d,, = 70 to 135 pm V-'> measured at 1064 nm. The bulky size and the local polarity of the diphenylphosphoryl acceptor group contribute to the high glass transition temperature (Tg = 120 to 163°C) and to the good temporal stability of these materials.
