Abstract

A novel rosarin di-Cu complex 2Cu-1 and a linear six-pyrrolic mono-copper complex 1Cu-1 were synthesized using rosarin as ligand. The molecular conformations of these complexes were confirmed by X-ray crystallography. The optical study of 1Cu-1 indicated the NIR-II absorption due to the long six-pyrrolic ligand and ICT effect. The 2Cu-1 complex displayed a very narrow electronic reduction - oxidation gap of 0.50 eV, attributed to the antiaromatic character of rosarin ring. The first HER study of di-copper rosarin complex 2Cu-1 indicated the multi-metal poly-pyrrolic complexes are powerful potential molecular hydrogen evolution reaction catalysts

玫瑰苷的铜络合：形成双铜玫瑰苷和单铜线性三吡咯啉

以玫瑰茄素为配体，合成了一种新型玫瑰茄素二铜络合物 2Cu-1 和一种线性六吡咯单铜络合物 1Cu-1。这些配合物的分子构象通过 X 射线晶体学得到了证实。1Cu-1 的光学研究表明，由于长的六吡咯配体和 ICT 效应，它具有近红外-II 吸收。2Cu-1 复合物显示出非常窄的电子还原-氧化间隙（0.50 eV），这归因于玫瑰苷环的反芳香特性。对玫瑰苷二铜络合物 2Cu-1 的首次氢反应研究表明，多金属多吡咯络合物是一种强大的潜在分子氢进化反应催化剂。
