Abstract
p-Diethynylbenzene was polymerized in the presence of cobalt-phosphine in diethylamine at room temperature with the yield of ca, 73.0% and t he Poly (p-diethynylbenzene) was obtained with the molecular weight of 11 000. The polymers, being highly soluble in common organic solvents , possess the structure containing pi-conjugated linear polyenes as th e main chain as well as p-ethynylbenzene component as pendant groups a nd emit intense fluorescence at 451.8 nm excited at UV light in a tolu ene solution at room temperature.
