Abstract

Sonogashira coupling is used for preparing a chromophore in which zinc porphyrin donors are linked through their meso positions by ethynyl bridges to a bis(indolinylidenemethyl) squaraine core. The chromophore has displayed a two-photon absorption spectrum characterized by a peak cross section of 11000 GM and has also displayed a large cross section of >780 GM over a photon-wavelength window.
