Design-dependent properties and applications of copper(I) bromide and fluorenylidene malononitrile coordination polymers
Abstract
Depending on the synthetic approach of the incorporation of fluorenylidenemalononitrile (L2) into a coordination polymer (CP), two different outcomes can be attained. In one case (UDS-6, [Cu2Br2(L2)2]n), the material turns out to be a photo-redox-active system with competing photophysical processes (1M/XLCT NIR emission, exciton migration and electron transfer), leading to tentative photovoltaic applications. In the other case, the hereby synthesized CP1 using a mono-cationic preassembly [Cu3(L1)2(Br)2]+ (L1 = bis(diphenylphosphinomethyl)phenylphosphine) turns out to be a visible 3M/XLCT emitter, as confirmed by extensive photophysical studies and theoretical investigations (DFT, TD-DFT, PW-DFT). Concurrently, this CP is found to be useful towards the photosensitization of singlet oxygen (¹Δg), as confirmed by the observation of the latter's intense phosphorescence signal at 1275 nm at the solid–gas interface. The dye degradation (rhodamine-6G) ability of CP1 was assessed but is limited by the rationalized instability of the material towards water
