Two New Zn(Ⅱ)/Cd(Ⅱ) One-dimensional Coordination Polymers Based on Naphthalimide Dicarboxylic Ligand |

| Abstract: | The assemble reactions of 5-(1,3-dioxo-~1H-benzode]isoquinolin-2(3 H)-yl)isophthalic acid(H_2L) and Zn2+/Cd2+ ions led to two compounds: ZnL(DMSO)2]?3DMSO(1) and Cd2 L2(DMSO)4]?DMF(2). 1 and 2 feature 1 D coordination chains. Weak ?-? interactions further connect the 1 D chains into 2D supramolecular networks. Upon grinding, 1 and 2 show increase of quantum efficiencies(34.8 and 45.4 times of increase compared with original samples for the two compounds respectively) and red shift of the emission peaks(45 and 41 nm of shift compared with original samples for the two compounds, respectively). Both indicate the compounds are good mechanoluminescence responsive materials. |
