THERMAL AND OPTICAL PROPERTIES OF MOLECULAR SIEVE AlPO₄-5 LOADED WITH NITROANILINE ISOMERS

Abstract

Nitroaniline isomers (o-, m-, and p-NA) were loaded in the one-dimensional channels of AlPO₄-5 by vapor-phase diffusion process, and the resulting materials (o-NA/AlPO₄-5, m-NA/AlPO₄-5, and p-NA/AlPO₄-5) were characterized. The maximum loadings for o-, m-, and p-NA were estimated to be about 1.8, 1.3, and 1.5 molecules per unit cell, respectively. The resulting materials exhibited nonlinear optical properties, and the order of the properties was found to be m-NA/AlPO₄-5<o-NA/AlPO₄-5 <<p-NA/AlPO₄-5 at maximum loadings.
