摘要
Two new coordination polymers (CPs) of {[Dy-2(abtc)(1.5)(H2O)(3)(DMA)]center dot H2O center dot DMA}(n) (1; DMA = NN-dimethylacetamide) and [NH2(CH3)(2)][Ni-1.5(abtc)]center dot H2O (2) were synthesized through utilizing 3,3',5,5'-azobenzenetetracarboxylic add (H(4)abtc) as an organic connector with the solvothermal reaction conditions. The HOMO-LUMO gap for ultra-stable complex 1 is 2.16 eV through the detection of the ultraviolet-visible spectrum with an absorption edge of 570 nm. The complex 1 reveals high catalytic effect for the ultraviolet-visible photocatalytic production of hydrogen, which is due to its light collection of the ligand with dye-like and porous architecture. Furthermore, the promotion effect of compounds 1 and 2 against the gastric cancer treatment was assessed when combined with intraperitoneal hyperthermia. Firstly, the inhibition of compounds 1 and 2 against the invasion and migration of cancer cells was evaluated with transwell assay. Moreover, the genes relative expression levels related with the reactive oxygen species (ROS) production in the cancer cells were also measured with real time reverse transcription-polymerase chain reaction (RT-PCR).
