Abstract
The lysozyme binding affinity and the electronic properties of [ReX (CO)(3)(terpy-kappa N-2(1),N-2)] (X = Br- and triazolate(COOCH2CH3,CF3)) were reported. The triazolate complex was prepared in a [3 + 2] cyclo-addition click reaction. The bromo compound reacted with lysozyme affording adducts with Re(CO)(3)(+) fragments, while the triazolate compound persisted. A red shift of the MLCT band of the triazolate compound in progressively less polar solvents may be due to the negative solvatochromism.
