用羟基官能化联吡啶合成含甲基丙烯酸甲酯的联吡啶单体。 2,2'-联吡啶的4'-甲基用于引入两种不同长度的羟基官能化烷基间隔基。采用两种不同的合成路线，通过溴代（C7 间隔基）或甲硅烷基化（C3 间隔基）中间体制备羟基官能化联吡啶。采用自由基共聚法制备了侧链带有联吡啶单元的聚甲基丙烯酸甲酯共聚物，并通过 1H NMR、紫外可见光谱、红外光谱以及凝胶渗透色谱进行了表征。共聚物的联吡啶单元与联吡啶钌前体反应。所得接枝共聚物表现出有前景的光物理和电化学性能，为太阳能电池器件领域的应用开辟了有趣的前景。 © 2003 Wiley periodicals, Inc.

Methyl methacrylate-containing bipyridine monomers were synthesized with a hydoxy-functionalized bipyridine. The 4′-methyl group of the 2,2′-bipyridine was used to introduce hydoxy-functionalized alkyl spacers of two different lengths. Two, different synthetic routes were applied for the preparation of the hydoxy-functionalized bipyridine via a bromo-(C7 spacer) or a silylated-(C3 spacer) intermediate. A copolymer of poly(methyl methacrylate) with bipyridine units in the side chains was prepared by free-radical copolymerization and characterized with 1H NMR, ultraviolet–visible, and IR spectroscopy as well as gel permeation chromatography. The bipyridine units of the copolymer were reacted with ruthenium bipyridine precursors. The resulting graft copolymers displayed promising photophysical and electrochemical properties, opening interesting perspectives for applications in the field of solar-cell devices. © 2003 Wiley Periodicals, Inc.
