Janus-type AT nucleosides: synthesis, solid and solution state structures.
Novel Janus-type nucleoside analogues (1a-d) were synthesized. Their pyrimido[4,5-d]pyrimidine base moiety has one face with a bidentate Watson-Crick donor-acceptor (DA) H-bond array of adenine and the other face with an acceptor-donor (AD) H-bond array of thymine. These nucleosides may self-associate through the self-complementary base pair. Indeed, in the solid state, compound 6d displayed a ...
متن کاملThe Solid Solution
The monoclinic silicates Lu2SiO5 and Sc2SiO5 (Y2SiO5 type, space groupC2/c) form a solid solution Lu2−xScxSiO5. Samples with x = 0.5, 0.8, 1.0 were synthesized ceramically from Lu2O3, Sc2O3, and SiO2. The structures of three crystals with x = 0.88, 0.77, and 0.50 were refined on the basis of single-crystal X-ray diffraction data. The rare earth (RE) atoms occupy two crystallographically differe...
متن کاملSilver solid solution piezoelectrics
Using density functional theory calculations, we investigate the feasibility of using silver on the perovskite A-site in high-performance lead-free piezoelectrics. The calculations show that silver atoms are ferroelectrically active and can off-center by 0.5 Å. To induce Ag ferroelctric behavior absent in pure AgNbO3 we explore solid solutions of AgNbO3 with well-known simple perovskites PbTiO3...
متن کاملGuest releasing from solution to solid-state triggered by cyclomaltohexaose (α-cyclodextrin) aggregation.
Supramolecuar aggregations 1 and 2 were prepared by complexing cyclomaltohexaose with two azodipyridine isomers: 4,4'-azodipyridine and 2,2'-azodipyridine, and their binding abilities and assembly behaviors were investigated comprehensively by X-ray crystallography, 2D NMR spectroscopy, and isothermal titration calorimetry. In solution, 1:1 host-guest complexation is generally assumed, whereas ...
متن کاملΑ-cycloaltrin: Conformation and Properties in the Solid- State and Aqueous Solution
Analysis of the conformational properties of α-cycloaltrin (α-CA) in aqueous solution by 800 MHz H, 200 MHz C NMR, and molecular dynamics (MD) simulations points towards a complex equilibrium of C1 S2 C4 altropyranose units. Although the JH-H coupling constants do not reveal a preference for the alternating C1 / C4 or the all-S2 conformation of α-CA, low-temperature C NMR line-broadening indica...
