Cationic polylysine promotes, under neutral conditions, the spontaneous aggregation of opposite charged ZnTPPS in water. Spectroscopic investigations evidence a different preorganization of ZnTPPS onto the polypeptide matrix depending on the chain length. Spinodal decomposition theory in confined geometry is used to model this mechanism by considering the time evolution of a homogeneous distribution of randomly adsorbed particles (porphyrins) onto a rodlike polyelectrolyte (polymer) of variable length L.

模板预组织效应驱动的卟啉超分子组装的手性增强

在中性条件下，阳离子聚赖氨酸可促进水中带相反电荷的ZnTPPS的自发聚集。光谱研究表明，取决于链长，ZnTPPS在多肽基质上的预组织不同。考虑到随机吸附的颗粒（卟啉）均匀分布到变长L的棒状聚电解质（聚合物）上的均匀时间分布，使用受限几何结构中的旋节线分解理论对这种机理进行建模。
