Light emission from self-assembled microstructures of phenylenevinylene polymers with dendritic side-groups

Summary form only given. Fundamental excitations in light-emitting polymers are of interest for their underlying photophysics and potential applications in light-emitting diodes. The fluorescence from light-emitting polymers is strongly influenced by aggregation of the polymer backbone, since aggregation provides a pathway for the excitation of inter-chain exciters. Polymer thin-films produced by standard spin-coating techniques suffer from a high degree of aggregation as indicated by their red-shifted fluorescence and a strong increase of the fluorescence lifetime. Thus, a better control of the film formation that would allow to influence the degree of aggregation or direct the formation of aggregates is highly desirable. Self-assembly of polymer structures presents a potential solution to this problem. Self-assembled molecular structures formed from organic light-emitting polymers have potential applications as laser materials or device materials for optical telecommunication.
