Molecular Motion and Energy Migration in Polymers.
Abstract
The first part of this report is concerned with research the aim of which is to establish whether or not electronic energy migration in synthetic polymers with pendant aromatic chromophores is a facile process or not. This is an area of some controversy, since authors regard the process as rapid, and proven to exist, others claim, largely on the basis of measurement of fluorescence anistropy, that it does not occur at all. We have synthesized two copolymer systems in an attempt to devise a more definitive experiment with which to test these conflicting hypotheses. These are polystyrene copolymerized with 0.01 percent of 2,5-diphenyl oxazole (PPO), and styrene-butadiene block copolymers.
