Bright green emitters with adjustable photoluminescence (PL) maxima in the range of 530-535 nm and full-width at half-maxima (fwhm) of <25 nm are particularly desirable for applications in television displays and related technologies. Toward this goal, we have developed a facile synthesis of highly monodisperse, cubic-shaped formamidinium lead bromide… (More)
Colloidal nanocrystals (NCs) of APbX3-type lead halide perovskites [A = Cs+, CH3NH3+ (methylammonium or MA+) or CH(NH2)2+ (formamidinium or FA+); X = Cl-, Br-, I-] have recently emerged as highly versatile photonic sources for applications ranging from simple photoluminescence down-conversion (e.g., for display backlighting) to light-emitting diodes. From… (More)
In the title compound, C(14)H(10)N(2)O(4)S(2),the furoxan heterocyclic ring and the two S atoms are almost co-planar, with a mean deviation of 0.036 Å. The bond lengths in the penta-gonal ring show electron delocalization and the furoxan N-O bond length is quite short [1.211 (3) Å]. The dihedral angles between the central ring and pendant phenyl rings are… (More)
Size and shape tunability and low-cost solution processability make colloidal lead chalcogenide quantum dots (QDs) an emerging class of building blocks for innovative photovoltaic, thermoelectric and optoelectronic devices. Lead chalcogenide QDs are known to crystallize in the rock-salt structure, although with very different atomic order and stoichiometry… (More)
The title compound, C(6)H(6)N(2)O(2), was obtained as a product of an in vitro study of the metabolism of benzofuroxan. The molecule exhibits a amphi configuration of the oxime groups C=N-OH. One oxime group is involved in the formation of a strong intra-molecular O-H⋯N hydrogen bond, while another links mol-ecules into zigzag chains along the c axis via… (More)
In the title compound, C(18)H(16)N(6)O(2)S, which belongs to the family of azo dyes, the dihedral angle between the benzene rings is 26.16 (7)°. In the crystal, mol-ecules are joined by N-H⋯N and C-H⋯N hydrogen bonds into double chains parallel to the a axis.
Faulted face-centred cubic platinum nanocrystals, grown within a nanoporous silica matrix, have been extensively characterized by the Debye function analysis method applied to wide-angle synchrotron X-ray total scattering data. A method for building databases of sampled interatomic distances of weakly faulted materials is proposed, maintaining statistical… (More)
Bioinspired in vitro collagen mineralization experiments have been performed in the presence of citrate and the combined role of the two bone organic matrix components in controlling mineral formation was investigated for the first time. Mineralized and non-mineralized collagen fibrils have been in depth characterized by combining small- and wide-angle… (More)
Crystal defects in highy luminescent colloidal nanocrystals (NCs) of CsPbX3 perovskites (X = Cl, Br, I) are investigated. Here, using X-ray total scattering techniques and the Debye scattering equation (DSE), we provide evidence that the local structure of these NCs always exhibits orthorhombic tilting of PbX6 octahedra within locally ordered subdomains.… (More)
In the crystal structure of the title compound, C(24)H(27)NO(11), a substituted tetra-acetyl glucopyran-oside derivative, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into ribbons propagated in . The d configuration has been attributed on the basis of the synthesis and the β anomer has been determined from the structure.
