| 英文摘要 | The ladder polyvinylsilsesquioxane (Vi-LPSQ) with high regularity was successfully synthesized via supramolecular architecture-directed stepwise coupling and polymerization: "synchronous growth polymerization, synchronous bridge-cleaving followed by in situ condensation". Formation with branches or cross-linking is unavoidable if the effective template is absent. Here, it is necessaryly emphasized that ladder superstructure (Vi-LS) and hydrogen-bonding adduct (HBA) are two imperative supramolecular architectures determining the ladder regularity of Vi-LPSQ. The ladder-rung, diaminophenylenes, can self-assemble into real ladder superstructures (Vi-LS) as template by pi-interaction-aided N-H's hydrogen-bonding. And when converting the real Vi-DLPS to the desired Vi-LPSQ, oxalyl chloride can initially form a stable hydrogen-bonded adduct ( HBA) with the diaminophenylenes-bridge of Vi-DLPS by a synergy of hydrogen bonding between carbonyl and amino groups and d pi-p pi interaction of p-electrons of Cl-atom and d-orbital of Si-atom. As a result, the reactive Vi-LPSQ is obtained based-on this supramolecular architectures-directed approach. The ladder regularities for either the Vi-DLPS or Vi-LPSQ are confirmed by the strong diffraction peaks at small angle range of XRD patterns. Especially, (29)Si-NMR measurement gives the sharp peak with extremely narrow baseline-width, Delta ca. 1, of the repeat moieties: Vi-Si (O(2/2))-NH-Ph-NH-Si(O(2/2))-Vi and Vi-Si(O(2/2))-O-Si(O(2/2))-Vi. Moreover, The target polymer Vi-LPSQ is a premising precursor for preparation of number of advanced functional materials due to a possibility of functionalization for the reactive vinyl group. |
