Abstract

Herein we demonstrate a synthetic protocol for the regioselective thiocyanation of corroles. To the best of our knowledge, thiocyanato appended corrole has never been reported earlier. The resulting thiocyanato appended corrole turned out to be a good corrole based precursor for the facile synthesis of thiol protected gold nanoparticles (Au NPs). The ligand system acts as a good bidentate framework and passivates the gold surface. A strong electronic interaction between the corrole and the gold nanoparticles is manifested by their unique photo physical properties and it also confirms that the binding through β-substitutions has a more pronounced effect even though the corrole rings are face-off to the gold surface.

摘要

在此,我们展示了一种用于卟啉区域选择性硫氰化的合成方案。据我们所知,硫氰酸根连接的卟啉此前从未有过报道。所得硫氰酸根连接的卟啉结果证明是用于简便合成硫醇保护的金纳米颗粒(Au NPs)的良好卟啉基前体。配体体系作为良好的双齿框架并钝化金表面。卟啉与金纳米颗粒之间的强电子相互作用通过它们独特的光物理性质得以体现,并且这也证实了尽管卟啉环与金表面面对面,但通过β-取代的结合具有更显著的效果。
