Research into low molecular weight coordination complexes, more specifically copper complexes bound by nitrogen rich ligands, are important in bioinorganic chemistry for their ability to do different functional group transformations and the opportunity for potential catalytic application. While copper complexes with bispicen (N,N’-dimethyl-N,N’-bis(pyridine-2-ylmethyl)1,2-diaminoethane) ligands have been explored for hydrocarbon functionalization, there hasn’t been much research towards their roles in other redox active reactions like electron transfer. In order to understand a complex role as potential electron acceptor it is fundamental to understand its electronic properties and how ligand structure impacts its electronic properties. Optical spectroscopy was used to investigate the electronic properties of the copper complexes that are supported by various ligands of bispicen family. Another factor to investigate is the efficiency of the copper complexes as quenchers under ruthenium-based photosensitizers. These can reveal the potential of photo-induce electron transfer reaction in these complexes as some of these copper complexes have different ligands and/or different rigidity on the backbone.
