3‐propanepione (DBM)‐functionalized SBA‐15 and SBA‐16 mesoporous hybrid materials (DBM‐SBA‐15 and DBM‐SBA‐16) are synthesized by co‐condensation of modified 1,3‐diphenyl‐1,3‐propanepione (DBM‐Si) and tetraethoxysilane (TEOS) in the presence of Pluronic P123 and Pluronic F127 as a template, respectively. The as‐synthesized mesoporous hybrid material DBM‐SBA‐15 and DBM‐SBA‐16 are used as the first precursor
1,3-二苯基-1,3-丙烷基酮(DBM)功能化的SBA-15和SBA-16介孔杂化材料(DBM-SBA-15和DBM-SBA-16)是通过改性1,3的共缩合而合成的分别以Pluronic P123和Pluronic F127为模板的-diphenyl-1,3-propanepione(DBM-Si)和四乙氧基硅烷(TEOS)。合成后的介孔杂化材料DBM‐SBA‐15和DBM‐SBA‐16被用作第一前体,而第二前体聚甲基丙烯酸(PMAA)是通过单体甲基丙烯酸的加成聚合反应合成的。然后这些前体同时与镧系元素离子配位,最终的中孔聚合物杂化材料Ln(DBM‐SBA‐15)3 PMAA和Ln(DBM‐SBA‐16)3PMAA(Ln = Eu,Tb)通过溶胶-凝胶法获得。为了进行比较,将二元镧系元素SBA-15和SBA-16中孔杂化材料(分别表示为Ln(DBM‐SBA‐15)3和Ln(DBM‐SBA
