Abstract

In view of the increasing importance of highly efficient light-emitting materials in chemistry, biological science, and materials science, we investigated the light-emitting efficiency tuning of rod-shaped oligo (p-phenylene ethynylene) s (OPEs, trimeric to pentameric systems) by donor and acceptor groups, so that they emit the very intense fluorescence (Φf≈ 1.0, log ε≈ 5) at 460 nm as the desired wavelength region. This goal was achieved by side ...
