| Outline of Final Research Achievements |
Cyclosiloxanes serve as multifunctional building blocks in this project. Boronic acid containing and catechol containing cyclosiloxane polymers were synthesized through one-pot two step hydrosilylation reaction. Dip-coating of these polymers showed good film forming ability on various organic and inorganic substrates. A crystalline tetramethylcyclotetrasiloxane (TMCS)-derived amphiphile was synthesized with eight peripheral hydrophilic amide groups and hydrophobic dodecyl chains by hydrosilylation and amidation
reactions. The as-synthesized materials form nanofibers spontaneously by good－poor solvent strategies, which contributes to porous three-dimensional (3D) structures possessing superhydrophobic surface wettability.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では、環状シロキサンポリマーの機能化により、ナノコーティングの可能性を追求している。カテコール基やボロン酸等の機能団修飾により、常温で液体である環状シロキサンポリマーを用いた最薄6nmのナノコーティングを実証している。このことはバルクとしてのシロキサンポリマーがナノスケールでの構造制御が可能であることを意味しており、ナノ材料としての環状シロキサンポリマーの研究展開が今後期待できる。
