Reaction of Cr(CO)(6) with trimesic acid in DMF affords the metal-organic framework Cr(3)(BTC)(2).nDMF (BTC(3-) = 1,3,5-benzenetricarboxylate), which is isostructural to Cu(3)(BTC)(2).3H(2)O. Exchanging DMF for methanol and heating at 160 degrees C under dynamic vacuum for 48 h results in the
Solvothermal reactions of equimolar zinc acetate, lithium acetate, and 1,3,5-benzenetricarboxylic acid (H(3)btc) in different mixed solvents yielded isostructural three-dimensional frameworks [LiZn(btc)(cG)].lG [cG and lG denote coordinated and lattice guests, respectively; cG = (nmp)(0.5)(H(2)O)(0.5), lG = (EtOH)(0.5) (1a); cG = H(2)O
A series of microporous lanthanide-organic framework enantiomers, Ln(BTC)(H(2)O)·(DMF)(1.1) (Ln = Y 1a, 1b; Tb 2a, 2b; Dy 3a, 3b; Er 4a, 4b; Yb 5a, 5b, BTC = 1,3,5-benzenetricarboxylate; DMF = N,N-dimethylformamide) with unprecedented (6,6)-connected topology have been prepared and characterized.
Quinacrine and related heterocyclic compounds have antiprion activity. Since the infectious pathogen of prion diseases is composed of multimeric PrP(Sc) assemblies, we hypothesized that this antiprion property could be enhanced by attaching multiple quinacrine-derived chloroquinoline or acridine moieties to a
The detection and identification of organic molecules on Mars are of prime importance to establish the existence of a possible ancient prebiotic chemistry or even a biological activity. To date, however, no complex organic compounds have been detected on Mars.
