A Transparent Planar Concentrator Using Aggregates of gem-Pyrene Ethenes

Banal, James; White, Jonathan; Lam, Tinwai; Ghiggino, Kenneth; Wong, Wallace Wing Ho; Blakers, Andrew


The luminescence properties of pyrene ethenes, both as monomer and aggregate species, are found to depend on the regioisomer structure. Systematic shifts in absorption, emission, and excitation spectra of the gem-pyrene ethenes, both in solution and in rigid polymer hosts, are consistent with weakly interacting H-aggregate formation. This aggregation leads to excimer-like emission with Stokes shifts greater than 1 eV. Planar concentrators fabricated from gem-pyrene diphenylethenes show...[Show more]
