blocks for creating metal–organic frameworks (MOFs) with controllable topologies. Herein, we describe the design and synthesis of a series of isoreticular MOFs featuring pcu topology [MOF-1114(RE) and MOF-1115(RE)] with variable rare earth metal ions (RE3+ = Y3+, Sm3+, Eu3+, Gd3+, Tb3+, Dy3+, Ho3+, Er3+, Tm3+, Yb3+) and linear amino-functionalized dicarboxylate linkers of different lengths. In total
第t d稀土点群对称性(RE 3+)金属簇RE 4(μ 3 -OH)4(COO)6 2+使得用于创建具有可控拓扑金属-有机骨架(MOF)他们有吸引力的构建块。在此,我们描述了一系列isoreticular的MOFs的特色的设计和合成PCU拓扑[ MOF-1114(RE)和MOF-1115(RE) ]具有可变稀土金属离子(RE 3+ = Y 3+,钐3+,Eu 3+,Gd 3+,Tb 3+,Dy 3+,Ho3+,Er 3+,Tm 3+,Yb 3+)和不同长度的线性氨基官能化二羧酸酯连接基。总之,我们报告22点的MOF,在这两种组合物和结构而变化但共享相同的RE 4(μ 3 -OH)4簇基序。我们证明这些pcu MOF是阳离子,阴离子交换可用于影响MOF属性。我们还研究了展示近红外发射的此MOF系列[ MOF-1114(Yb) ]中具有代表性的成员的发光特性。我们证明了Yb 3+的激发能 可以
