Abstract
Abstract Two novel poly(1-alkyne)s containing azobenzene nonlinear optical chromophoric group, poly(4-(4-[4-( n -dodecyloxy)phenylazophenyl]carbonyl)oxy-1-butyne) (P 1 ) and poly(11-(4-[4-( n -dodecyloxy)phenylazophenyl]carbonyl)oxy-1-undecyne) (P 2 ), were synthesized by [Rh(nbd)Cl] 2 –Et 3 N catalysts and characterized by FTIR, 1 H 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.
