porous MOF, LCuPRO. The free l-proline moiety in the cavity of the framework in the presence of imidazole as a cocatalyst functions synergistically to catalyze the Baylis–Hillman reaction between α,β-unsaturated carbonyl compounds and aromatic aldehydes. High porosity of the framework is proven by the nitrogen adsorption isotherm.
1-脯氨酸已经在刚性线性配体H 4 L中共价连接,所述刚性线性配体H 4 L在每个末端具有间苯二甲酸酯部分以形成手性配体H 4 LPRO。该连接体已用于构建多孔MOF L Cu PRO。自由升在咪唑存在作为助催化剂功能的框架的空腔-脯氨酸部分协同催化α,β不饱和羰基化合物和芳族醛类之间的的Baylis-Hillman反应。氮吸附等温线证明了骨架的高孔隙率。
