The fluorescence quenching of a Zn(II) porphyrin linked to Cu(I) catenates relative to a model compound without Cu(I) was attributed to energy transfer from the Zn(II) porphyrin to the metal-to-ligand charge transfer (MLCT) state of the Cu(I) (phenanthroline)~2~ center at the core of the molecules.

Triphenyl pyrazoline derivative, 1,3-diphenyl-5-{4-[2-(4-(phenylazo)phenoxy)ethyloxy]phenyl}-2-pyrazoline (compound III), was synthesized and its optical properties were studied by UV-VIS and fluorescence spectroscopies. The UV-VIS spectrum showed that the electronic transition bands of azobenzene a
Fluorescence lifetime measurements were made for the S, origins of a number of jet-cooled indole chromophores having carbonyl-containing substituents bonded directly to the chromophore with no spacing aliphatic carbons. The lifetimes are signiticantly shorter than those of compounds having carbonyl
