Our group has devoted ourselves to the method using cobalt complexes to control the polymerization. Recently, we discovered a new method using the organic compounds of tralen derivatives to approach the control of vinyl acetate and acrylates polymerization. We prepared various block copolymers that have a more significant amphiphilicity than the random copolymers and thus become an ideal surfactant. In this subproject, we will use the block copolymers as the surfactant to disperse the pentiptycene derivatives in the polymer thin film. With different quantity and types of surfactants, the size and dispersity of particles formed by pentiptycene derivatives could be adjusted. In other words, the number of pentiptycene molecules in a particle and the distance between the pentiptycene particles could be tuned to explore the stimuli-responsive behavior of pentiptycene derivatives from micrometer level to nanometer level, which will provide the mechanistic understanding for the unique properties of pentiptycene derivatives. We are expecting the influence of packing and morphology of pentiptycene molecules on its stimuli-responsive behavior could be disclosed and the physical properties of the thin film could be enhanced by hybridization with pentiptycene derivatives to broaden the impact of this series of pentiptycene derivatives to the chemistry and materials society.五苯荑;嵌段共聚物;刺激響應行為;pentiptycene;block copolymers;stimuli-responsive behavior
