Abstract

A series of organic/inorganic molecular hybrid nonlinear optical materials were prepared by incorporating azobenzene nonlinear optical chromophores into nanosized, inorganic, polyhedral oligomeric silsesquioxane. Each of the hybrids was soluble in common solvents such as CHCl3, THF, toluene and C2H4Cl2, and exhibited good film-forming properties. Their structures and properties were characterized using FTIR, 1H NMR, 13C NMR, 29Si NMR, UV, TGA, DSC and nonlinear optical analyses, respectively. All hybrid compounds displayed good optical limiting properties, large nonlinear optical response and high thermal stability. The optical limiting mechanism was investigated.
