Bis(allylammonium)pentachloroantimonate(III) – allylammonium chloride, (C3H5NH3)2[SbCl5] · (C3H5NH3)Cl, belongs to the chloroantimonate(III) organic-inorganic salts family. The DSC studies of this compound showed two anomalies at 181 K and at 223 K. Both are associated with phase transitions, which mainly occur due to ordering-disordering processes of the organic cations. Between 181 and 223 K ...

Gels with the ability to immobilize a liquid phase are structures of three-dimensional network. These types of gels consist of two parts, gelling agent (network forming) and liquid solvent phase (hydrophilic or hydrophobic). However, depending on the polarity of the liquid immobilized within the networked structure, gels may be termed either as hydro gels (polar solvent-water) or organogels (or...

Organic-inorganic hybrid metal halide perovskites, an emerging class of solution processable photoactive materials, welcome a new member with a one-dimensional structure. Herein we report the synthesis, crystal structure and photophysical properties of one-dimensional organic lead bromide perovskites, C4N2H14PbBr4, in which the edge sharing octahedral lead bromide chains [PbBr4 2-]∞ are surroun...

We use surface x-ray diffraction to study the structure of organic-organic heterojunctions grown by organic molecular-beam deposition. In particular, we study films of 3,4,9,10-perylenetetracarboxylic dianhydride ~PTCDA! grown on a decanethiol self-assembled monolayer ~SAM! on a Au~111! surface. The deposition of several ('16) monolayers of PTCDA results in unstrained crystalline films whose ~0...

The advancement of organic electronics for applications in solar-energy conversion, printed circuitry, displays, and solidstate lighting depends upon the optimization of a variety of organic-semiconductor interfaces. Organic-semiconductor/ insulator (O/I) interfaces, in particular, are critical to the operation of organic thin-film transistors (OTFTs) currently being developed for printed flexi...

Hourglass-shaped Ni nanoparticles were synthesized with a hexagonal close packed (hcp) structure. The unconventional crystalline structure could be stabilized by intensive utilization of hexadecylamine. The dense organic layer on the surface protected the meta-stable crystalline structure.

This work reports the color-tunable mixed photoluminescence (PL) emission from an Alq3 organic layer in an Au-Alq3-Au plasmonic structure through the combination of organic fluorescence emission and another form of emission that is enabled by the surface plasmons in the plasmonic structure. The emission wavelength of the latter depends on the Alq3 thickness and can be tuned within the Alq3 fluo...
