摘要：

The synthesis and properties of conjugated polymers containing organoboron quinolate in their main chain was analyzed. The boron center in monomer B(4-iodophenyl)2q have been determined by single-crystal X-ray diffraction analysis that displays a typical tetrahedral geometry. The hydroxyquinoline groups in all four molecules are chelated to boron to form a five-membered chelate ring. Coupling reactions utilizing Pd and Cu catalysts between B(4-iodophenyl)2q and diyne monomers gave the corresponding polymers. The resulting polymers were dissolved in chloroform and transferred into a separatory funnel and then washed three times with water to remove salts and catalysts. The desired polymers were purified by reprecipitation from diethyl ether. The structures of all products were supported by NMR and elemental analysis. The results of elemental analysis were reasonable with containing iodophenyl groups.
