Controllable preparation and properties of active functional hybrid materials with different chromophores

Abstract

A convenient and efficient strategy for preparing active functional hybrid materials was proposed based on an investigation of the controllable preparation of a series of anthracene-containing organic–inorganic functional hybrid materials with active ethylene groups. These functional hybrid materials with different active vinyls were controllably prepared through a Heck reaction with octavinyl-polyhedral oligomeric silsesquioxane (OV-POSS) as the raw material by adjusting the feed ratio. Their structures and properties were characterized and evaluated by various measurements. The influence of molecular structure on the optical properties of the resulting hybrids was investigated in detail. It was found that the incorporation of nano-sized inorganic polyhedral oligomeric silsesquioxane (POSS) can efficiently prevent aggregation of hybrid molecules owing to the prohibition of π–π stacking between chromophore groups, which was also confirmed by theoretical simulation. Simultaneously, thermogravimetric analysis (TGA) results also show that the inorganic POSS causes the good thermal stabilities of the hybrids.
