Singlet and triplet exciton energy migration in the charge-transfer crystal of pyromellitie dianhydride-phenanthrene, undoped and doped with anthracene (10-4-10-2 M/M), have been studied in the 5-300 K temperature range. At low temperatures singlet and triplet excitons are self-trapped. They become

## Abstract Attaching electron‐rich 1,3‐dithiol‐2‐ylidene moieties to polynitrofluorene electron acceptors leads to the formation of highly conjugated compounds **6** to **11**, which combine high electron affinity with a pronounced intramolecular charge transfer (ICT) that is manifested as an inte
