ABSTRACT:
The compounds 4-chloro-4'-hydroxybenzophenone, methyl 3,4-diaminobenzoate, N-(4-aminobenzenesulfonyl)-acetamide, methyl 4-hydroxy-3,5-dimethoxybenzoate, 2-chloro-4-cyano-6-methylaniline, 4'-hydroxy-2-phenylacetophenone and methyl 3,4-dihydroxybenzoate form high quality crystals with high melting point. They are useful for second order non-linear optical process devices such as wavelength conversion devices.
