Synthesis of controlled architecture macromolecules has been a major objective in the fields of polymer science and chemistry. In this respect, metalloporphyrins are excellent initiators for the controlled polymerization of a wide variety of monomers, and have been provided several new aspects in this field. For example, "Immortal Polymerization" by combination of metalloporphyrin initiators with protic chain transfer agents is a new class of living polymerization that enables the synthesis of narrow MWD polymers with the number of the polymer molecules exceeding that of the initiator molecules. "High-Speed Living Polymerization" by combination of metalloporphyrin initiators with Lewis acids has provided a dramatically rapid synthesis of narrow MWD polymers with Mn exceeding 10^6. Novel "Visible Light-Driven Living Anionic Polymerization and Copolymerization" have been also realized.

可控结构大分子的合成一直是高分子科学和化学领域的一个重要目标。在这方面，金属卟啉是用于多种单体的可控聚合的优异引发剂，并且在该领域中提供了若干新的方面。例如，通过金属卟啉引发剂与质子链转移剂的组合的“不朽聚合”是一类新的活性聚合，其使得能够合成窄MWD聚合物，其中聚合物分子的数目超过引发剂分子的数目。通过金属卟啉引发剂与刘易斯酸的组合的“高速活性聚合”提供了Mn超过10^6的窄MWD聚合物的显著快速合成。还实现了新型的“可见光驱动的活性阴离子聚合和共聚”。
