Four new compounds [Co2(NDC)2(AzBIPY)] (1), [Cu2(NDC)2(AzBIPY)] (2), [Zn2(BPDC)2(AzBIPY)] (3) and [Zn2(CCA)2(AzBIPY)] (4) (with H2NDC: 2, 6-naphthalenedicarboxylic acid, AzBIPY: 3-azo-phenyl-4, 4′-bipyridine, H2BPDC: 4, 4′-biphenyl-dicarboxylic acid and H2CCA: 4-carboxy-cinnamic acid) were synthesized and characterized. All compounds have paddle-wheel units and photo switchable linker molecules in
四种新化合物[Co2(NDC)2(AzBIPY)](1)、[Cu2(NDC)2(AzBIPY)](2)、[Zn2(BPDC)2(AzBIPY)](3)和[Zn2(CCA) 2(AzBIPY)] (4)(含 H2NDC:2, 6-萘二甲酸,AzBIPY:3-azo-phenyl-4, 4'-bipyridine,H2BPDC:4, 4'-biphenyl-二甲酸和 H2CCA:4-羧基肉桂酸)被合成和表征。所有化合物都具有共同的桨轮单元和光可切换连接分子。在所有四种化合物中,AzBIPY 接头分子的偶氮基团都突出到孔中。对于化合物 1 和 2,异构化可以在用紫外光 (λ = 365 nm) 照射后完成,以将热力学稳定的反式异构体转变为顺式异构体。可以通过热或可见光 (λ = 455 nm) 照射来实现反向切换。
