Harvesting excited spin-triplet states as light is essential to realize highly efficient
electroluminescence (EL) in organic light-emitting devices. In recent years, thermally …

This review discusses charge transfer (CT) interactions in wholly aromatic polyimides (PI).
Discussion was extended to the influence of CT interactions on PI properties, ie …

Engineering the electronic excited state manifolds of organic molecules can give rise to
various functional outcomes, including ambient triplet harvesting, that has received …

Light emission from organic light-emitting diodes that make use of fluorescent materials
have an internal quantum efficiency that is typically limited to no more than 25% due to the …

Time-resolved electron paramagnetic resonance studies show that the primary mechanism
of triplet formation following photoexcitation of julolidine-anthracene molecules linked by a …

The relationship between radiative and nonradiative electron transfer is explored for return
electron transfer processes in the contact radical-ion pairs formed by excitation of ground …

This review presents some of the efforts that have been made over the last decades to
produce systems in which photo-excitation leads to one or more intramolecular electron …

Exactly 4 decades ago Mulliken1 introduced the concept of charge transfer (CT) transitions.
This refers to direct excitation into a state involving complete transfer of an electron from a …

Four different 1, 8-naphthalimide derivatives were examined in phosphorescent organic light
emitting diodes (OLEDs), ie, 1, 8-naphthalimide, N-phenyl-1, 8-naphthalimide, N-2, 6 …

Highly efficient exciplex systems incorporating a heptazine derivative (HAP-3MF) as an
electron acceptor and 1, 3-di (9H-carbazol-9-yl) benzene (mCP) as an electron donor are …
