Abstract : The principal focus of the project is to develop new materials chemistry based on molecular level design and solid state chemistry. The goals have been to develop electroactive polymers with novel electronic, optical and nonlinear optical properties. Second and third order nonlinear optical materials have been developed based on conjugated macromolecules and asymmetric anharmonic molecular electronic dipolar oscillators. In this multidisciplinary research effort, starting from first principle, bulk self assembly processing techniques needed to control the molecular and supermolecular organizations of optical and electroactive molecules have been developed. They include spontaneous molecular organization of nonlinear optically active conjugated polymers such as polydiacetylenes with conjugating and hydrogen bonding side groups. A series of new soluble PDAs of the same class with further functionalization, elaborating on the already defined design principle have been developed. (MM)
