Five
novel 3D lithium–organic frameworks, [Li2(H2pml)]·C4H8O2 (1, H4pml = 1,2,4,5-benzenetetracarboxylic or pyromellitic
acid), [Li2(H2pml)] (2), [Li(H2tatab)]·5H2O (3, H3tatab = 4,4′,4″-s-triazine-1,3,5-triyltri-p-aminobenzoic acid), [Li11(H3O)(H2O)5(Html)6]·8C4H8O2 (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.
