Invisible photochromism of diarylethene derivatives.
Diarylethene derivatives with oxidized thiophene rings shift their absorption band to a shorter wavelength in the UV region upon photocyclization; no color change was observed during the photochromic reaction, and the invisible photochromism is advantageous for devices used under room light.
متن کامل(3-Hydroxy-2-pyridylmethyl)dimethylammonium dihydrogenphosphate.
The title compound, C8H13N2O + H2PO4, is an ionic salt. The organic species is protonated at the N atom of the dimethylaminomethyl group. The dihydrogenphosphate moieties are connected into in®nite chains by way of OÐH O links. The H2PO4 ÿ group also makes an OÐH N hydrogen bond to the pyridine N atom of the organic species. The organic cations crosslink the phosphate chains into a three-dimens...
متن کاملThe surface and solution properties of dihexadecyl dimethylammonium bromide.
The surface adsorption behavior and solution aggregate microstructure of the dichain cationic surfactant dihexadecyl dimethylammonium bromide (DHDAB) have been studied using small angle neutron scattering (SANS), light scattering, neutron reflectivity (NR), and surface tension (ST). Using a combination of surface tension and neutron reflectivity, the DHDAB equilibrium surface excess at saturati...
متن کاملPhotochromism of diarylethene molecules and crystals
Photochromism is defined as a reversible transformation of a chemical species between two isomers upon photoirradiation. Although vast numbers of photochromic molecules have been so far reported, photochromic molecules which exhibit thermally irreversible photochromic reactivity are limited to a few examples. The thermal irreversibility is an indispensable property for the application of photoc...
متن کاملPhotochromism of a spirooxazine in the single crystalline phase.
The single crystals of a closed form spirooxazine spiro[azahomoadamantane-isoquinolinoxazine] were found for the first time to undergo photocoloration processes consistent with photochromism in the single crystalline phase.
