A multidonor–photosensitizer–multiacceptor triad for long-lived directional charge separation

Abstract

The modular assembly of a directional photoredox-active multidonor–photosensitizer–multiacceptor (Dn–P–Am) architecture is presented. The triad assembly features a central Ru(II) sensitizer equipped with pendant polymer chains consisting of multiple triarylamine (pTARA) and naphthalene diimide (pNDI) units, respectively. Upon excitation, the efficient formation (>96%) of charge separation (CS) was observed featuring similar CS lifetimes (400 ns) as related molecular triads. In contrast, a significant additional longer-lived CS component (2400 ns, 30%) is observed indicating multiple contributing pathways.
