碩士 國立暨南國際大學 應用化學系 105 A series of fluorescent metal-organic frameworks (MOFs) based on Cd(II) and N-(pyridin-4-yl)-4-(pydrin-4-yl)-1,8-naphthalimide (NI-bipy-44) with different aromatic dicarboxylates were synthesized. Cd2(1,4-bdc)2(NI-bipy-44)2 (1, 1,4-H2bdc = 1,4-benzenedicarboxylic acid), Cd2(1,4-bdc-Br)2(NI-bipy-44)2 (2, 1,4-H2bdc-Br = 2-bromoterephthalic acid), Cd2(1,4-bdc-NO2)2(NI-bipy-44)2 (3, 1,4-H2bdc-NO2 = 2-nitroterephthalic acid), and Cd2(BPDC)2(NI-bipy-44)2 (4, H2BPDC = biphenyl-4,4′-dicarboxylic acid) have similar structures suiting a 3D pillared-layer framework with porosity of 58.4%, 51.4%, 51.5%, and 41.4%, respectively. Of note, compound 4 is 2-fold interpenetration, while compounds 1-3 are non-interpenetration. Compounds 1-4 exhibit intense solid-state photoluminescence with λmax of 450 ± 5 nm, making them useful for detecting small organic molecules and nitro compounds. When compounds 1 and 2 were soaked in H2O and DMSO, there was a significant fluorescence quenching. On the other
