Optimization of thermal stability and second-order nonlinear optical properties of thiophene derived chromophores
Abstract
Based on the ‘unconventional’ dithiolydinemethyl type donors and tricyanovinyl acceptor; a new series of highly efficient (βµ= 940–2400 × 10–48 esu) and thermally stable (275–315 °C) thiophene derived nonlinear optical chromophores have been developed.
