Comparing Spin‐Selective Charge Transport through Donor–Bridge–Acceptor Molecules with Different Oligomeric Aromatic Bridges

Burning bridges: The exponential distance dependence (β value) of singlet and triplet charge recombination (CR) pathways is determined for three donor-bridge-acceptor (DBA) molecules. p-Phenylethynylene and fluorenone bridges have similar β values, which differ significantly from those of p-phenylene bridges (see picture), thus implying that β for both singlet and triplet CR is system-dependent, not bridge-specific.
