Check Digit Verification of cas no

The CAS Registry Mumber 42906-19-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,9,0 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 42906-19:
(7*4)+(6*2)+(5*9)+(4*0)+(3*6)+(2*1)+(1*9)=114
114 % 10 = 4
So 42906-19-4 is a valid CAS Registry Number.

Crystal structure of p-formylphenyl, di(p-methylphenyl)amine, and p-bromophenyl, di(o-bromo-p-methylphenyl)amine

Xue, Minzhao,Liu, Yangang,Huang, Deyin,Gong, Bin

, p. 749 - 753 (2000)

p-Formylphenyl, di(p-methylphenyl)amine (1), and p-bromophenyl, di(o-bromo-p-methylphenyl)amine (2) were prepared and characterized by X-ray crystallography. Formyl-substituted triphenylamine(1) crystallizes in the monoclinic space group P21/c with a = 9.068(1), b = 17.115(2), c = 11.297(2) A, β = 106.73(1)°, V = 1679.0(5) A3 and Z =4. Bromo -substituted compound 2 crystallizes in the monoclinic space group P21/n with a = 16.170(4), b = 7.9477(8), c = 16.906(4) A, β = 117.67(2)°, V = 1924.1(7) A3 and Z = 4. The N atoms deviate slightly from the plane of the bonded C atoms and the benzene ring planes are rotated by 25-67° to avoid overlap of the ortho-substituted atoms. The major force of crystal formation comes from the multiple phenyl embraces (MPE).

, p. 431 - 440 (2017/02/10)

Donor-acceptor type triphenylamine-based malonodinitriles were synthesized and their thermal, optical, photophysical, electrochemical and nonlinear optical properties were studied. The synthesized compounds formed glasses with the glass transition temperatures ranging from 38 to 107 °C. The ionization potentials of the samples of the compounds established by cyclic voltammetry were found to be in the range of 5.50–5.57 eV, while those estimated by photoelectron emission spectrometry ranged from 5.36 to 5.74 eV. The electron affinity values of the compounds were found to be in the range of ?3.41–?3.05 eV. The ambipolar charge-transporting properties were observed for the layers of triphenylamine-based malonodinitriles. Hole mobilities of the layers of the compounds were in the range of 10?7–10?6 cm2/V·s, while electron mobilities were by ca. two orders of magnitude higher. All the synthesized compounds had positive sign for second order hyperpolarizability.

Efficient delayed fluorescence via triplet-triplet annihilation for deep-blue electroluminescence

Chou,Chou,Chen,Su,Liao,Lin,Lin,Yen,Chen,Cheng

, p. 6869 - 6871 (2014/06/23)

Four 2-(styryl)triphenylene derivatives (TSs) were synthesized for deep-blue dopant materials. By using a pyrene-containing compound, DMPPP, as the host, the TS-doped devices exhibited significant delayed fluorescence via triplet-triplet annihilation, providing the highest quantum efficiency of 10.2% and a current efficiency of 12.3 cd A-1. the Partner Organisations 2014.

Electrochromic properties of novel chalcones containing triphenylamine moiety

Jin, Huiyi,Li, Xianggao,Tan, Tingfeng,Wang, Shirong,Xiao, Yin,Tian, Jianhua

, p. 154 - 160 (2014/04/17)

A series of novel electrochromic chalcones containing triphenylamine units were synthesized by Aldol reaction and characterized by NMR, IR and MS. Their optical, electrochemical properties were investigated using UV-vis, photoluminescence spectra and cyclic voltammetry. The molecular orbital energy levels and excitation energies were calculated by quantum chemical calculation. It was found that the fluorescence intensity is decreasing with formation of charge-transfer state. The existence of electron donating group on triphenylamine unites caused a significant bathochromic shift of the UV absorption maximum and increased EHOMO and ELUMO. The electrochromic property of the synthesized compounds was studied by spectroelectrochemical experiments. The results showed that the chalcones containing triphenylamine moiety presented good electrochromic stability, with a color change from yellow to blue as applied potentials ranging from 0.0 to 2.8 V. The coloring and bleaching time was in the range of 2.9-4.2 s and 1.7-3.3 s, respectively.
