Synthesis and properties of conjugated phenylene ethynylene derivatives

Abstract

Fourteen new conjugated phenylene ethynylene derivatives as potential molecular electronic devices are presented here. These new compounds were synthesized by convergent synthetic methodologies which are based on Sonogashira and Suzuki couplings. The synthesized compounds were identified by 1H NMR, 13C NMR, IR, HRMS and elemental analysis. The UV-vis maximum absorption spectra were in the range of 304-321 nm in CHCl 3. Cyclic voltammetry (CV) test results showed two distinct reduction peaks. © ARKAT USA, Inc.
