The studies revealed that these two merocyanines exist in solutions as nonpolar (quinoid, i.e. vinylogous amide, ) or polar (zwitterionic, i.e. betaine, ) forms in their ground state, respectively. The dye with a nitro substituent can also form a hydrogen-bonded betaine (). This dye is...
The present invention also provides a NO2sensor and a UV sensor, each of which uses the wire-type supercapacitor. The NO2sensor can stably detect NO2gas on fabric for a long time. The UV sensor can be attached to fabric to detect UV in color or quantitatively photocurrent. The present i...
The metal–organic frameworks UiO-66 with single or binary −(OH)2 and −NO2 functional groups were synthesized, and their structures and properties were characterized by Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, scanning electron microscopy, and nitrogen ...
Experimentalists have also studied, (15N2O)2,11,14,17 (15N14NO)2,5 14N2O-15N2O,13,14 and 15N14NO-15N2O.14 For all of these isotopologues they have determined rotational constants for the ground vibrational state of the polar and/or nonpolar forms. Rotational constants for the torsion, ...
Materials and growth issues for high-performance nonpolar and semipolar light-emitting devices Growth of InGaN/GaN light-emitting devices on nonpolar or semipolar planes offers a viable approach to reducing or eliminating the issues associated with p... RM Farrell,EC Young,F Wu,... - 《Semicond...
Although this method was developed for the determination of micromolar quantities of nitro-尾-hydroperoxides in lipid samples, it can be used to determine any long chain, nonpolar nitro compound. The method also can be adapted to allow the determination of polar or short chain nitro compounds by...
Ultraviolet spectra of a number of 2(2-hydroxyphenyl)2H-benzotriazoles were studied in nonpolar, polar, and hydrogen bonding solvents. The effect of substituents located in the 4-position of the benzo-triazole ring was investigated, and the effect on the UV absorption characteristics of 2(2-...
X bond dissociation energies (BDEs) of the highly polar cyanopolyynes HC2n +1N versus the analogous nonpolar dicyanopolyynes NC2n N diminish as the intervening carbon chain length increases, indicating that the local bond polarity of the coordinating CN group dominates over the ligand''s overall...
