共轭卟啉聚合物是一种巨大的超分子生色团，具有优异的电光和非线性光学性质。合成有机化学家、化学物理学家和理论家之间的密切合作，为这些非凡材料的电子结构提供了新的见解。炔连接的低聚物已经被最深入地研究。几股独立的工作表明，这些材料的不寻常的电子行为可以归因于强大的基态interporphine共轭，这是放大的激发态，并在氧化和还原形式。
Conjugated porphyrin polymers are giant supramolecular chromophores with extraordinary electrooptical and nonlinear optical properties. Close collaboration between synthetic organic chemists, chemical physicists and theoreticians has yielded new insights into the electronic structure of these remarkable materials. Alkyne-linked oligomers have been most intensively investigated. Several strands of independent work show that the unusual electronic behaviour of these materials can be attributed to strong ground state interporphyrin conjugation, which is amplified in the excited states, and in the oxidised and reduced forms.
