Based on the designed tripodal linker 1,3,5-tris(2-methylimidazol-1-yl)benzene (timb), four cobalt(II) coordination polymers, {[Co4(timb)2(Br–IPA)4]·5H2O}n (1), {[Co(timb)0.5(NH2–IPA)]·4H2O}n (2), {[Co5(timb)4(OH–IPA)4]·2NO3·2DMA·2H2O}n (3), and {[Co3(timb)2(SO3–IPA)2(H2O)2]·8H2O}n (4), have been obtained by adjusting the meta-functional groups of isophthalic acid (H2IPA). CP 1 displays an unprecedented 3D 3-nodal (3,4,8)-connected net with the point (Schlafli) symbol {42·64}{42·6}2{46·614·74·83·9} based on trinuclear {Co3(COO)6} SBUs. CP 2 shows an interesting 2D (3,4)-connected {63}{66} bilayer with ABAB packing. CP 3 is a 2D 6-nodal (3,3,3,4,4,4)-connected sheet with the point (Schlafli) symbol {4·52}{4·53·72}2{42·52·6·7}3{43}{53}2. CP 4 exhibits a 2D + 2D → 3D interpenetrating net based on the 2D (3,4)-connected {63}{66} bilayer structure. CPs 1–4 possess excellent luminescence sensing properties for Fe3+ and Cr2O72− ions in aqueous solution with high sensitivity and selectivity. Besides, the magnetic properties as well as the photocatalytic activities for the degradation of methylene blue (MB) of CPs 1–4 under visible light have been investigated.

官能团诱导的四种基于1,3,5-三(2-甲基咪唑-1-基)苯的钴(II)配位聚合物的结构多样性以及光催化,磁性和发光传感性能

基于设计的三脚架连接子1,3,5-三(2-甲基咪唑-1-基)苯(timb),四种钴(II)配位聚合物,{[Co 4(timb)2(Br–IPA)4 ] ·5H 2 O} n1),{[Co(timb)0.5(NH 2 -IPA)]·4H 2 O} n2),{[Co 5(timb)4(OH-IPA)4 ]· 2NO 3 ·2DMA·2H 2 O} n3)和{[Co 3(timb)2(SO 3 –IPA)2(H 2 O) 2 ]·8H 2 ö} Ñ 4),可以通过调整所获得的间苯二甲酸(H官能化的基团2 IPA)。CP 1显示了前所未有的3D 3节点(3,4,8)连接的网络,其点(Schlafli)符号为{4 2 ·6 4 } {4 2 ·6} 2 {4 6 ·6 14 ·7 4 · 8 3 ·9}基于三核{Co 3(COO) 6 } SBU。CP 2显示了有趣的2D(3,4)连接{6 3} {6 6 }具有ABAB填料的双层。CP 3是2D 6节点(3,3,3,4,4,4)连接的片,其点(Schlafli)符号为{4·5 2 } {4·5 3 ·7 2 } 2 {4 2 ·5 2 ·6·7} 3 {4 3 } {5 3 } 2。CP 4展示了基于2D(3,4)连接的{6 3 } {6 6 }双层结构的2D + 2D→3D互穿网络。CP 1-4具有出色的Fe 3+和Cr 2 O 7 2-发光传感特性。水溶液中的离子具有高灵敏度和选择性。此外,还研究了在可见光下对CP 1–4的亚甲基蓝(MB)降解的磁性和光催化活性。
