Dynamic models and computer simulation of local motions shown in polarized luminescence of labeled polymers

Abstract

Theoretical approach to the relationships of molecular mobility manifested in the polarized luminescence involves several problems. (1) The investigation of the mobility of a given chain element unperturbed by a marker (“phantom” marker). (2) The study of heterogeneous dynamic chain models in which the differences between the statistic and dynamic parameters of the labeled element and those of a standard chain element are taken into account. (3) The computer simulation of the rotational mobility of chains containing phantom or real markers. (4) The introducing of the concept of kinetic segment based on the specific features of the kinetics of longitudinal relaxation processes in polymer chains. The experimentally observed relationships of polarized luminescence of labeled macromolecules in solutions and those of some other local relaxation properties are discussed in terms of theoretical treatments mentioned above. © 1984 IUPAC
