Photophysical and Photochemical Properties of 2,3-Dihydro-4(l H)-quinolinones. Part I. Fluorescence Properties
Absorption spectra and fluorescence properties o f 2,3-dihydro-4( 1 H)-quinolinone deriva tives were studied at room temperature in different solvents. It has been found that the fluo rescence quantum yields and fluorescence decay times strongly depend on the molecular struc ture and solvent polarity. The character and the energy o f excited states were determined by PPP and CNDO /S quantum-...
متن کاملFluorescence from an H-aggregated naphthalenediimide based peptide: photophysical and computational investigation of this rare phenomenon.
Fluorescence associated with J-aggregated naphthalenediimides (NDIs) is common. However, in this study an NDI based synthetic peptide molecule is found to form a fluorescent H-aggregate in a chloroform (CHCl3)-methylcyclohexane (MCH) mixture. An attempt has been made to explain the unusual fluorescence property of this H-aggregated NDI derivative. Time correlated single photon counting (TCSPC) ...
متن کاملComparison of photophysical and colloidal properties of biocompatible semiconductor nanocrystals using fluorescence correlation spectroscopy.
A number of different surface chemistries have been developed in recent years to render semiconductor nanocrystals (NCs) stable in water and biocompatible. However, most of these surface modifications affect NCs' photophysical properties, calling for a method to simultaneously monitor colloidal and fluorescence properties. Fluorescence correlation spectroscopy (FCS) combined with ensemble spect...
متن کاملSynthesis and photophysical properties of multinuclear zinc-salophen complexes: enhancement of fluorescence by fluorene termini.
Incorporation of fluorene groups into the salicylidene moiety significantly enhances the luminescence of a number of multinuclear alkynylated Zn(II)-salophen complexes. Preparation of these complexes was achieved by a synthetic strategy with facile handling of the reactants, simple purification of the products, and one-pot reaction process. Two synthetic methods are used for the preparation of ...
متن کاملFluorescence and photophysical properties of xylene isomers in water: with experimental and theoretical approaches
A thorough analysis of the photophysical properties involved in electronic transitions in excitation-emission spectra of xylene isomers has been carried out using the time-dependent density functional theory (PBEPBE/6-31 + G(d,p)) method. For the first time a structural and spectroscopic investigation to distinguish isomers of xylene, a widespread priority pollutant, was conducted experimentall...
