Polarized Luminescence of Macromolecules with Conjugated Luminescent Markers

2 Polarized Luminescence PL) of Macromolecules with Conjugated Luminescent Markers 

The theoretical analysis of the relationship between small-scale relaxation processes in polymers PL reveals just these processes) and the intra- or intermolecular inter-actions shows that these processes are sensitive to various changes in the number (probability of formation) of intra- or interchain contacts in polymer solutions. The experimental data reveal that the intramolecular mobility (IMM) of the polymer in solution is highly susceptible to various conformational transformations of macro-molecules and to changes in the intermolecular interactions in complex multicom- 

The high effectiveness of the PL method for solving various problems of polymer chemistry and physics is mostly due to the features that distinguish this method from other methods applied to the investigation of the structure and properties of polymers in multicomponent polymer systems in solution. 

The possibility of carrying out investigations in very dilute solutions at a polymer content in solution as low as 0.001%. This means that the effect of interchain contacts superimposed on intramacromolecular interactions is greatly weakened or completely absent. This weakening is particularly important when the polymer-polymer interactions sharply increase, e.g. by the action of the precipitant  

The PL method permits to carry out investigations in any solvents polar and nonpolar solvents, in water, in the presence of charged particles and at any temperatures
