“…As was shown in many papers, Jablonski's theory of concentrational quenching of luminescence [11,12,29,36,[37][38][39][40] and its generalisation by Kawski [22,41,42] and Bojarski [43,44] is in good agreement with experiment. In the present paper it is shown that Jablonski's model of a luminescence centrum acquires a new meaning as a real physical object of well defined physico-chemical properties in micellar solutions.…”

A theoretical description of micellar dye solutions containing donors and acceptors is developed. It is proved experimentally that the luminescent characteristics of Water-Triton X-100 solutions of Coumarine 1 as a donor and Rhodamine 6G as an acceptor are consistent with the proposed theory. It is shown that the probability of energy transfer between dye molecules and the number of detergent molecules in a micelle may be obtained.

The fluorescence quenching of 2-aminopurine and 2-phenylindole, acting a sensitizers, by 2-aminobenzophenon, acting as acceptor, in viscous solvents (Glycerol + 5% methanol) and its influence on the emission anisotropy (EA) of the sensitizer were investigated. It was found that the relation rj/rjo -r/ro (rj/rjo the relative quantum yield and T/TO the relative mean lifetime of the excited sensitizer) in this case is good fulfiled. The behaviour of the EA in the investigated acceptor concentration range is discussed. Abb. 1.

Flexibility of a labeled polymer chain: Time‐resolved fluorescence depolarization measurements and their interpretation by a Hinged‐Dumbbell model

SynopsisTime-resolved fluorescence depolarization was applied to investigate the dynamics of low-molecular-weight polyethylene glycols ( M W 150, 400, 1000, 4000) labeled by fluorescein-isothiocyanate. The analysis of measurements revealed considerable flexibility of the polymer chain. To interpret the observed dependence of the relaxation time of polarization anisotropy on the molecular weight of the polymer, a simple freely-hinged dumbbell model was developed. The properties of the model were investigated by computer experiments.The model was found to account well for the measured data.
