A Study on Fluorescence Quenching of Dicyanoanthracene by Acenaphthenone via Electron Transfer──Formation Machanism of Exciplex and Its Kinetics;

This paper reports the synthesis of naphthalene-bridged biscrownether, and the equilibrium and dynamic conversion between self-assembly excimer and PET process induced by different concentration o

Study on the Excimer Fluorescence Behavior of α,ω-Biscoumarin Long Chain Compounds;

An excimer fluorescent emission was observed for the lowest generation (G0F), and fluorescein-fluorescein complex fluorescent emissions were observed for the first generation (G1F) and the second-gene.

It is due to the fact that the interaction between urea groups perturbs the π π overlap of naphthyl groups resulting in a negative effect on the excimer formation of naphthalene.

It was found that the fluorescence emission of these compounds can be quenched strongly by the aluminum tris(8 hydroxyquinoline), and simultaneously a new emissive band which was assigned to the exciplex formation appeared in the long wavelength region of fluorescence spectrum.

Two kinds of binary compounds containing pyrene and aniline moiety were designed and synthesized, and the influence of solvent polarity and viscosity on the formation of their intramolecular exciplex was investigated.

Upon irradiation, intramolecular electron transfer from moiety An to DCVB occurred, exciplex formed and triplet energy transfer took place.
