Popis:	1-(4′-Substituted phenyl)-4-(4′-methylpyridinium)butadiyne triflate (5ab), which was prepared by the reaction of 1-(4′-Substituted phenyl)-4-(4′-pyridyl) butadiyne (4ab) with methyl trifluoromethanesulfonate, was found to be grown into the large crystal due to the quaternized structure. The uv irradiation and thermal treatment of 5ab gave rise to 1,4-addition polymerization to yield the polydiacetylene. The third-order nonlinear optical susceptibility (χ (3)) of the polymer was determined by the Z-Scan method to exhibit the remarkable high value of 1.65×10−11esu at 650 nm.
