Abstract

To create organic molecules that are highly fluorescent at a longer wavelength region, we investigated the synthesis (using Pd-catalyzed cross-coupling) and photophysical properties (Φf, λem, τ, λabs, and ε) of the following π conjugated molecular rods consisting of p- phenyleneethynylene units modified by donor (OMe) and/or acceptor (CN) groups:(1) side- donor modification systems (SD systems),(2) side-acceptor modification systems (SA ...
