Copper Complexation of Rosarin: Formation of a Bis-copper Rosarin and a Mono-copper Linear Tridipyrrin
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
