We report the synthesis and characterization of six novel coordination polymers (CPs) based on M(II) (M: Zn and Co), di-, tri-, and tetracarboxylate linkers and two novel bis-pyridylalcohol 1,7-bis(pyridin-n′-yl)methanol}-1,7-dicarba-closo-dodecaboranes (n′ = 3, L1; n′ = 4, L2) ligands. The polycarboxylates are terephthalic acid (H2BDC), 1,3,5-benzenetricarboxylic acid (H3BTB), and 1,2,4,5-tetrak
我们报告了基于M(II)(M:Zn和Co),二,三和四羧酸酯连接基和两个新颖的双吡啶醇1,7-bis (吡啶ñ -1'-基)甲醇} -1,7-二dicarba-闭合碳-dodecaboranes(ñ '= 3,L1 ; ñ '= 4,L2)配体。所述多羧酸盐是对苯二甲酸(H 2 BDC),1,3,5-苯三羧酸(H 3 BTB)和1,2,4,5-四(4-羧基苯基)苯(H 4 TCPB)。CP的结构描述揭示了碳硼烷配体的灵活性及其构建扩展结构的能力。CP包含Co(II),BTB和L2充当各种客体的结晶海绵,对芳族客体分子显示出更高的亲和力。单晶纳米压痕实验表明,客体和CP框架之间的大量特定相互作用导致了较高的弹性模量和硬度值。
