2-브로모에틸 에틸 에테르를 이용한 2-에티닐피리딘의 중합을 통한 이온형 공액구조 고분자

A new ionic conjugated polymer with side-chain ether moieties was synthesized by the catalyst-freee polymerization of 2-ethynylpyridine using 2-bromoethyl ethyl ether. The polymerization proceeded easily in relatively mild reaction condition to yield 89% of polymer. The polymer structure was characterized by various instrumental methods such as NMR, IR, and UV-visible spectroscopies to have a conjugated backbone system with the designed substituents. This polymer was completely soluble in water and polar organic solvents such as DMF, DMSO, DMAc, and methanol. The electrochemical and electro-optical properties of the resulting polymer were measured and discussed.
