摘要：
Two novel poly(1-alkyne)s containing azobenzene nonlinear optical chromophoric group, poly(4-(4-[4-(n-dodecyloxy)phenylazophenyl]carbonyl)oxy-1-butyne) (P1) and poly(11-(4-[4-(n-dodecyloxy)phenylazophenyl]carbonyl)oxy-1-undecyne) (P2), were synthesized by [Rh(nbd)Cl](2)-Et3N catalysts and characterized by FTIR, H-1 NMR, GPC and UV-vis techniques. Their optical limiting and nonlinear optical properties were investigated using 8 ns pulse at 532 nm. The results show that these soluble functional poly(1-alkyne)s possess good optical limiting properties and large nonlinear optical properties. (c) 2006 Elsevier Ltd. All rights reserved.
