Abstract

Abstract: A new ferrocene–porphyrin derivative, namely 5, 15-bisferrocenyl-porphyrinato zinc was designed and synthesized. Its self-assembly behavior in the absence and presence of 4, 4′-bipyridine had been comparatively investigated. Depending on the intermolecular π–π interaction, the ferrocene–porphyrin self-assembled into lotus flower-like nanostructures in the absence of 4, 4′-bipyridine. However, when the equivalent of 4, 4′-bipyridine was added into the self-assembly solution of the ferrocene–porphyrin, nanobelts were obtained depending mainly on the Zn–N4, 4′-bipyridine coordination bonds between the zinc atom of the ferrocene–porphyrin and the nitrogen atom of the additional 4, 4′-bipyridine. Further investigation about the nonlinear optical properties of both aggregates revealed that the nanostructures fabricated from the ferrocene–porphyrin exhibited saturation absorption in the absence of 4, 4′-bipyridine and reverse saturation absorption in the presence of 4, 4′-bipyridine. Graphical abstract: A new ferrocene-porphyrin derivative, namely 5, 15-bisferrocenyl-porphyrinato-znic (ZnPorFC2 ) was designed and synthesized. Its self-assembly behavior and the nonlinear optical (NLO) properties in the absence and presence of 4, 4′-bipyridine were comparatively investigated, indicating the effective influence of metal-ligand coordination on the morphology, dimension and nonlinear optical properties of assembled aggregates. Highlights: A new ferrocene–porphyrin derivative was designed and synthesized. Self-assembly behavior and the nonlinear optical properties were investigated. The metal-ligand coordination effect on the self-assembled aggregates was studied.
