Outline of Final Research Achievements

In this study, we aim to develop a novel method for controlling polymer structures based on a new concept, which involves reversibly converting stable dormant species, traditionally used to suppress side reactions in polymerization, into multiple multi-active species by controlling the electronic state of carbon atoms using multiple stimuli. By combining this approach with other reaction systems such as click reactions, we aim to form a single polymer chain through heterogeneous reactions. By reversible activation of the dormant species of conventional living polymerization or chemically converting them into azide groups, we explored an innovative method for precision polymer synthesis that allows for flexible design of polymers. In addition, we aim to evaluate the properties of the resulting polymer materials.

Academic Significance and Societal Importance of the Research Achievements

本研究課題においては最終的にカチオンやラジカルといったアクティブ種に限定することなく、クリック反応を取り入れたビニルモノマーの重合全般において、マルチアクティブ種変換を行い、これまでの精密重合化学の集大成と言っても過言ではない革新的な自在高分子合成法の確立を目指し、これまでにはないクリックリビング重合の開発に成功した。最近ではこのような概念の重要性が高分子合成の分野で徐々に認識され始め、類似の研究例もいくつか報告されてきており、本分野で世界をリードし続けるためにも、本課題の更なる発展が重要と考えられ、社会的な意義も大きい。
