摘要

本研究以硝酸鋅與雙吡啶橋接配體N-(pyridin-4-yl)-4-(pydrin-4-yl)-1,8-naphthalimide (NI-bipy-44) 和二酸類化合物經溶劑熱法合成出一系列具螢光性的有機金屬框架：[Zn3(1,4-chdc)3(NI-bipy-44)] (1)，[Zn2(1,4-BDC-Br)2(NI-bipy-44)] (2)，[Zn3(bpdc)3(NI-bipy-44)] (3) 和 [Zn3(bpdc)2(NI-bipy-44) ] (4)。
化合物2、4具有類似的結構，它們都是三維的層柱狀結構，整體具有二次互穿的特性；化合物1、3具有類似的結構，都是三維的三角柱結構。
化合物1、2和4於424 nm有明顯的螢光訊號，可使用於溶液相硝基化合物的螢光感測和氣相硝基感測。此外，化合物14都表現出對CO2的吸附能力。

Fluorescent metal－organic frameworks (MOFs) [Zn3(1,4-chdc)3(NI-bipy-44)] (1), [Zn2(1,4-BDC-Br)2(NI-bipy-44)] (2), [Zn3(bpdc)3(NI-bipy-44)] (3) and [Zn3(bpdc)2(NI-bipy-44)] (4), were constructed from the hydro(solvo)thermal reactions of zinc nitrate, N-(pyridin-4-yl)-4-(pyridin-4-yl)-1,8-naphthalimide (NI-bipy-44), a well-designed dipyridyl bridging ligand, and dicarboxylic acids (1,4-H2chdc = trans-1,4-cyclohexanedicarboxylic acid, 1,4-H2bdc-Br = 2-bromoterephthalic acid, H2bpdc = biphenyl-4,4′-dicarboxylic acid). Compounds 2 and 4 have similar structures suiting a 3D pillared-layer structure, and overall 2-fold interpenetration, while compounds 1 and 3 have a 3D triangular prism structure.
Compounds 1、2 and 4 exhibit intense solid-state photoluminescence with λmax of ~424 nm, making them useful for sensing nitro compounds and sensing of the nitro analytes were carried out in the vapor phase. In addition, compounds 1-4 have shown gas adsorption abilities for CO2
