Description
Summary:At the focal point of this work is the photophysical characterization of three meso–meso ethene‐bridged diporphyrins featuring a diverse metallation pattern. Detailed investigations by means of cyclic voltammetry, absorption, fluorescence, and femto‐/nanosecond transient absorption spectroscopy revealed the impact of open‐shell nickel(II) on the electronic communication in ethene‐bridged heterobimetallic diporphyrins. Donor–acceptor systems: Study of electronic communication in a series of meso–meso ethene‐bridged unsymmetrical diporphyrins is reported. Detailed physicochemical investigation revealed the impact of open‐shell nickel(II) on the electronic communication in ethene‐bridged heterobimetallic diporphyrins (see figure).
