摘要：

Straight-chain alkyl and analogous polymethylene esters and amides of nitrophenyl carbamic acids (urethanes and ureas) have been found to yield acentric crystals having nonlinear optical properties. These crystals displayed powder second harmonic generation efficiencies ranging from 0 to 154 times that of urea, depending on the crystallizing solvent and the crystallizing conditions employed. Powder X-ray diffraction D spacings were employed to characterize the exact crystal form of each sample of material studied.
