| 摘 要： | 利用表面活性剂作为导向剂,将三聚氰胺苯酚甲醛低聚物通过溶剂挥发诱导自组装技术合成出三聚氰胺功能化介孔高分子材料(Melamine-MPs).所制备的Melamine-MPs材料在水介质中的Knoevenagel缩合反应中显示出和母体相当的催化活性,并可用于重复6次.其原因可能是来自于材料表面疏水性以及介孔孔道所形成的纳米反应器.同时,嵌入孔壁中的三聚氰胺官能团可以抑制活性组分的离去,从而获得相对良好的耐久性.

| Abstract: | Melamine-functionalized mesoporous polymers(melamine-MPs) were synthesized through the surfactant-directed melamine-phenol-formaldehyde oligomers self-assembly approach.The as-prepared melamine-MPs material exhibited comparable catalytic activity with the parent melamine in water-medium Knoevenagel condensation reactions and could be used repetitively for six times.The excellent activity could be attributed to the high surface hydrophobicity and meso-structure of the nanoreactors.Meanwhile,the melamine func... |
