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 …

Photoinduced electron transfer is a widely applied method to convert photon energy into a
useful (electro) chemical potential, both in nature and in artificial devices. There is a …

The target donor− acceptor compound forms an acridinium-like, locally excited (LE) singlet
state on illumination with blue or near-UV light. This LE state undergoes rapid charge …

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

The rates of excited-state intramolecular electron transfer in 9-(4-biphenyl)-10-
methylacridinium (BPAc+), crystal violet lactone (CVL), and bianthryl have been measured …

The optical spectroscopic properties of 1, 4 (and 5)-benzenedicarboxylic acid, 2-[10-
(dimethylamino)-4-fluoro-3-oxo-3H-benzo [c] xanthen-7-yl](carboxy SNARF-4F), a …

Crystal violet lactone (CVL) in solution displays unusually broad (FWHM> 9100 cm− 1) dual
fluorescence with the characteristics of white light. The emission combines a blue CT band …

Crystal violet lactone (CVL) emits in aprotic solvents at room temperature single (A band,
low polar solvents) or dual (A and B bands, medium and highly polar solvents) fluorescence …

Excited intramolecular charge‐transfer states have been attracting significant attention in
recent decades, as they are crucial for different optoelectronic applications including the …

The equilibrium between different tautomers that can be colored or colorless is an important
feature for rhodamine dyes. Presently, this phenomenon is mostly discussed for rhodamine …
