Owing to the numerous advantages of organic semiconductors for device applications including low cost, lightweight, ease of fabrication and feasibility for flexible devices, organic optoelectronics and photonics have developed rapidly in the past decades. Organic solar cells showing promising potential as alternative inexpensive and renewable energy sources have also received considerable attention from both academia and industry. In addition, the multiphoton absorbing materials offer many advantages for the technological applications of biological imaging and sensing, frequency up-converted lasing, high capacity data storage, photodynamic therapy, as well as three-dimensional microfabrication. As part of broad program in developing efficient and stable new functional materials for optoelectronic and electronic applications, we propose to develop novel fused aromatic derived low-bandgap polymeric systems with high absorptivity and charges carrier mobility for solution-processable, high-efficiency heterojunction photovoltaic devices as well as to design and synthesize novel series of highly extended and coplanar ladder-type π-conjugated oligomers with high fluorescence quantum yields and large multiphoton absorption cross-sections for multiphoton excited fluorescence and lasing applications.
