| Outline of Final Research Achievements |
Aiming at investigating the structural correlations for physical properties of organic molecular clusters, some dispersion states, for example, molecule state, cluster, and organic nanocrystals, could be experimentally controlled suitably by finely optimizing the rates of phase separation, segregation, and crystallization of organic molecules embedded polymer microspheres that is a so-called extremely limited small space. “Phase separation in polymerization field and subsequent nanocrystallization process” has been developed successfully in perylene and polystyrene (PS) system. Actually, the state of perylene dispersed in polymer microspheres was analyzed and evaluated by the measurements with the conventional fluorescence spectroscopy, near-field scanning optical microscopy, and positron annihilation method. As a result, the intermediate dispersion state would be strongly suggested for the first time in the case of perylene embedded in PS microshperes.
