Synthesis and optical properties of multibranched and C sub(3) symmetrical oligomers with benzene or triphenylamine core and diazines as peripheral groups

We report therein the synthesis and photophysical properties of a new series of two- and tribranched compounds built up from benzene or triphenylamine as central core and electron-withdrawing diazine rings as peripheral group. The arms allowing connection between these two parts are constituted by a...

Description
Summary:We report therein the synthesis and photophysical properties of a new series of two- and tribranched compounds built up from benzene or triphenylamine as central core and electron-withdrawing diazine rings as peripheral group. The arms allowing connection between these two parts are constituted by an ethynylene linker. All these compounds are fluorescent and are of particular interest with generally good quantum yields and good Stokes shifts. Some of them have been tested for two-photon absorption (TPA) properties and had revealed interesting performances.
