Potential Applications of Self-assembled π-Systems

Self-assembly of functional molecules such as linear π-systems is important in the field of advanced materials for optoelectronic applications. During self-assembly the electronic interaction within the molecules induces significant changes in the properties such as absorption, fluorescence and electronic conductivity. Oligo(p-phenylenevinylene)s (OPVs) are a class of fluorescent linear π-systems that are being used for a variety of applications. For the past several years we have been investigating the self-assembly of OPVs, which form a variety of supramolecularstructures leading to gelationof organic solvents. Through functional group modification and control of supramolecularinteraction, we were able to tune the emission of a variety of molecular self-assemblies leading to organogelsthat emit at different wavelengths. These soft materials are excellent scaffolds as energy donors. Results of these studies will be presented.
