N2 - Five novel 3D lithium-organic frameworks, [Li2(H 2pml)]·C4H8O2 (1, H 4pml = 1,2,4,5-benzenetetracarboxylic or pyromellitic acid), [Li 2(H2pml)] (2), [Li(H2tatab)]·5H 2O (3, H3tatab = 4,4′,4″-s-triazine-1,3,5- triyltri-p-aminobenzoic acid), [Li11(H3O)(H 2O)5(Html)6]·8C4H 8O2 (4, H3tml = 1,2,4-benzenetricarboxylic or trimellitic acid), and [Li{Li(nmp)}{Li(H2O)(nmp)}{Li(nmp) 2}2(H2tms)(Htms)2] ·NMP·EtOH (5, H3tms = 1,3,5-benzenetricarboxylic or trimesic acid, nmp = 1-methyl-2-pyrrolidinone), were synthesized by solvothermal methods and characterized by single crystal X-ray diffraction, powder X-ray diffraction (PXRD), IR spectroscopy, and thermogravimetric analyses (TGA). Compounds 1 and 2 feature the same framework composition but different guest-controlled structures and topology. Compound 4 consists of a unique undecanuclear Li carboxylate complex {Li11(H2O) 5(RCOO)18} and contains pores with diameter 7 Å. Furthermore, compound 4 demonstrates highly pronounced guest-dependent photoluminescence behavior: nitrobenzene completely quenches the light emission, while toluene enhances it.
