Controlled Molecular Orders in Layered Multiple Porphyrins.

ABSTRACT: Nature precisely regulates multicomponent assemblies with the assistance of cooperativity. However, establishing such high precision in multicomponent assemblies of artificial supramolecular structures remains challenging. Here, we successfully position multiple distinct guest molecules within two equivalent binding cavities of a zinc-metalated trisporphyrin host by combining two distinct negative cooperative interactions, including donor-acceptor π-stacking and metal-ligand coordination. Comprehensive characterization using UV-vis absorption spectroscopy and diffusion-ordered NMR spectroscopy confirmed the exclusive formation of a ternary supramolecular complex. X-ray crystallographic analysis further revealed that the introduction of an additional bridging ligand effectively linked the t
