Abstract
By mixing with polymer and inorganic substances in a molecular level, organic-inorganic hybrids which have both functions derived from each component can be obtained. We can also tune the properties of the materials by changing the contents or types of organic components. In this review, we survey the series of studies on organic-inorganic hybrids. The design strategy and the applications for the hybrid materials are described. Moreover, we also present the polyhedral oligomeric silsesquioxane (POSS)-based functional materials. Unique characteristics originated from the structural features of POSS are explained.
