| 제목 | Nano-coating of functional cyclosiloxane polymers containing dynamic covalent bond boronic acid |
| 초록 | We noted cyclosiloxane with four functional groups as a good choice for post functionalization. A novel boronic-acid containing polycyclosiloxane was designed and synthesized through introduction of boronic acid side groups into the linear polycyclosiloxane backbone. The reaction was done using a one-pot-two-step hydrosilylation reaction: first, 4 functional cyclosiloxane reacted with 2 functional linear siloxane at a mixing ratio of 1:1 and second, mixed with allylboronic acid pinacol ester to react with the remaining –Si–H on the linear polycyclosiloxane. The chemical structures, film formation and thermal properties of the obtained polymers were characterized using NMR, FT-IR, AFM, and TGA. Then, boronic-acid-containing polycyclosiloxane was demonstrated that has low surface energy, which provide the polymer with good nanocoating capability. Finally, the nano-film was observed using dye molecules as reusable Zn ion sensitive optical probes. [1] S. Kim, H. Zhu, A. Demirci, S. Yamamoto, T. Miyashita and M.
