Abstract

Abstract Functionalized oligo (phenylene-ethynylene) s (OPEs) with different conjugation lengths, pX (C 6 H 4 C≡ C) n SiMe 3 (n= 1–4; X= NH 2, NMe 2, H) were synthesized by Sonogashira coupling of (phenylene-ethynylene) s and 1-iodo-4-(trimethylsilylethynyl) benzene, followed by desilylation of the p-substituted (trimethylsilylethynyl) benzenes with potassium hydroxide. The photoluminescent properties for the OPE series with different ...
