摘要
为模拟天然卟啉所具有的特殊生理活性,结构与性能各异的多种金属卟啉被合成并应用于许多领域。实际上,天然金属卟啉是在特定天然高分子-蛋白质营造的空穴中才能发挥其独特的性质,因此,类卟啉金属配合物的高分子化逐渐受到关注,并在载氧、催化、导电等领域取得重要成果。基于结合方式不同,高分子类卟啉金属配合物可分为高分子担载类卟啉金属配合物与聚类卟啉金属配合物。其中,后者以稳定的类卟啉环作为高分子链,不但使高分子骨架稳定,而且活性中心与类卟啉金属配合物之间有效间隔,同时活性中心相对密集,使其表现出较高的稳定性与活性。线形与平面型聚金属卟啉与金属酞菁表现出良好的导电性与催化活性;手性Salen席夫碱易于聚合得到线形或网状聚Salen席夫碱金属配合物,表现出较强的催化活性、高ee值和可循环性。异双核聚类卟啉金属配合物也表现出较强的催化活化分子氧性能。
In order to mimic the function of natural metalloporphyrin, many kinds of metalloporphyrins are synthesized and applied in different fields. It is also found that natural metalloporphyrins show excellent activities only in protein cave, which is surrounded with natural polymer chains. Therefore, polymer quasi-porphyrin metal complexes have been noticed by more and more researchers because of their excellent performances in transmission oxygen, catalytic oxidation, electrical conductivity, and so on. According to bonding method, polymer quasi-porphyrin metal complexes can be divided into polymer supported quasi-metalloporphyrins and polymeric quasi-porphyrin metal complexes. Compared with polymer supported quasi-metalloporphyrins, polymeric quasi-porphyrin metal complexes exhibit higher stability and activity. Crosslinked with bifunctional group compound, the porphyrin or phthalocyanine can be polycondensed, which afford line and sheet polymeric metalloporphyrins or sheet polymeric phthalocyanine. They exhibit high conductivity and catalytic activity. Chiral Salen Shift-base metal complexes can be polymerized, which afford chiral line or net polymeric Salen metal complexes. They show good catalytic activity with high ee value and recycle ability. Some heterodinuclear polymeric metal complexes with different quasi-porphyrin metal complexes also show catalytic aerobic oxidation behavior.
