摘要：

Novel monomers and polymers containing arylenevinylideneethynylene groups were synthesized via the Heck reaction. The polymers were amorphous and soluble in common organic solvents. They showed T-g around 60 degrees C and 5% weight loss in the region of 240-340 degrees C and underwent thermal cross-linking on heating to 170-190 degrees C at the expense of triple bonds. One of the polymers showed strong blue luminescence with emission maxima around 380-390 and 470-480nm with excitation at 320 nm. All polymers showed nonlinear optical susceptibility of the third order (chi((3))) around 10(-10) esu.
