Microporous polymers whose pore size under 2 nm have the advantage of high surface area. Adsorbent or heterogeneous catalyst are potential applications owing to high surface area of microporous polymers. Hyper-cross-linked polymer (HCP) is a class of microporous polymers by arresting free volume in polymer by additional rigid cross-linking. Microporous polymer has low efficiency to utilize overall pore surfaces due to the low diffusion rate. HPP having larger pores have been studied to solve the problem by enhancing diffusion rate through larger pores. This thesis explains results of studies based on the synthesis of hierarchically porous polymers from block polymer precursors. First, chapter 1 contains brief introduction to hyper-cross-linked polymer and block polymer. Chapter 2 explains a route to synthesize HPP which has micropore and well-defined 3D continuous mesopore from block polymer and its porosity control by adjusting compositions of polymerization mixture. Chapter 3 describes the synthetic condition for fluorescent HPPs and their further emission color modification by adsorption and energy transfer from fluorescent surface to adsorbate.
