International audience; The steric strain around copper(I) in typical [Cu(NNR)2] + complexes, where NNR is a diimine ligand substituted in α of the nitrogen atoms by R, is known to strongly impact the excited-state properties. Generally speaking, th

The reductive quenching of photoexcited photosensitizers is a very efficient way to achieve challenging reduction reactions. In this process, the excited photosensitizer is reduced by a sacrificial electron donor. This mechanism is rarely observed wi

While copper(I)-bis(diimine) complexes [Cu-I(L)(2)](+) are considered as potent substitutes for [Ru-II(bpy)(3)](2+), they exhibit low molar extinction coefficients with respect to ruthenium parent analogues. One interesting possibility to improve the
