Outline of Final Research Achievements

In this research, we are aimed at a preparation of metalic meso-helical structure arrays by using helical structures of block copolymers as a templete. To control of handedness of helical structures of block copolymers, the chiral compounds were covalently attached to the chemical junction between first and second polymer segments in the linear triblock terpolymer by click reaction. The helical polymer domains were successfully metalized by complexation reaction and subsequent thermal reduction.
