STUDY OF MACROMOLECULAR CONFIGURATION OF POLYFLUORENES IN SOLUTION
We propose to study by small angle neutron scattering a family of polyfluorenes, which are based on poly(9,9-dioctylfluorene). The materials have been designed to provide insight into the effect on charge transport of a number of key factors influencing molecular packing, in particular the structure and number of side-chains and the polymer molecular weight. During the experiments, the temperature dependence of the structural transitions will be carefully studied for solutions at low volume fraction. The SANS scans on the solutions will be performed at several temperatures, ranging between 300K and 450K, in order to study the radious of gyration of the macromolecule, the conformational changes in solution and the possible onset of a coil-globular transition and the aggregation/nucleation points of crystallization during processing in solution as a function of temperature.
