Perylene-tethered pillar [5] arenes and C60–boron-dipyrromethene (BODIPY) dyads were
synthesized acting as emitters and organic triplet photosensitizers, respectively, for the …

Phenothiazine (PTZ)–anthracene (An) compact electron donor/acceptor dyads were
synthesized. The molecular conformation was constrained by rotation restriction to achieve …

In order to study the relationship between the molecular structures of compact electron
donor/acceptor dyads and the spin–orbit charge transfer intersystem crossing (SOCT-ISC) …

BODIPY heterochromophores, asymmetrically substituted with perylene and/or iodine at the
2 and 6 positions were prepared and investigated as sensitizers for triplet‐triplet annihilation …

A boron dipyrromethane (BDP)-containing Pt (II)–Schiff base complex (Pt-BDP), showing
ping-pong singlet–triplet energy transfer, was synthesized, and the detailed photophysical …

process is initiated by the capture of photons and the subsequent energy delivery, is a …

We attached different electron donors of phenyl, anthryl, and alkylamino moieties, to electron
acceptor naphthalenediimide (NDI) to construct compact electron donor/acceptor dyads. The …
