Check Digit Verification of cas no

The CAS Registry Mumber 654067-65-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,4,0,6 and 7 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 654067-65:
169 % 10 = 9
So 654067-65-9 is a valid CAS Registry Number.

Highly solvatochromic fluorescence of anthraquinone dyes based on triphenylamines

Li, Yanxia,Tan, Tingfeng,Wang, Shirong,Xiao, Yin,Li, Xianggao

, p. 262 - 270 (2017/06/05)

Five donor-acceptor anthraquinone dyes based on phenylamine/triphenylamines with different substituted groups were synthesized by Suzuki reaction in good yields, and the photophysical properties were studied in organic solvents with different polarity. The title dyes exhibited remarkable solvatochromic fluorescence (>190 nm emission shift in polar media), which was derived from intramolecular charge transfer (ICT) character that revealed by DFT/TD-DFT calculation. And large Stokes shifts (210–306 nm) were observed in different organic solvents, along with rich color changes from blue to green, yellow, orange and even purple-red. The Stokes shifts were linearly dependent on the solvent polarity function ET(30). Interestingly, it was found from the single-crystal X-ray diffraction analysis that dye 3 displayed two different interleaved channel structures, which was seldom seen in organic compounds and could be used as host for complexation potentially. Electrochemical characterization suggested that the different substituted phenylamine groups attached to anthraquinone unit could lead to tunable potentials and energy levels.

The main body of the triphenylamine constructing macrocyclic and a plurality of lateral branch hole transport material, triphenylamine


Paragraph 0040-0042, (2017/02/28)

The invention provides a hole-transporting material with main body big ring built by triphenylamine and replaced by a plurality of triphenylamine lateral branches. 2-bromine fluorenone is built to triphenylamine monomer containing functional groups capable of reacting with each other, three molecules of monomers are further cyclized, and at least three triphenylamine lateral branch structures are built at the side of the big ring to form electron-rich hole-transporting material containing a plurality of main body big ring and lateral branches built by triphenylamine through simple chemical reaction. The electron-rich formulae a, b and c big ring type triarylamine compounds have approximate three-dimensional spherical structures. The synthetic electron-rich big ring type triarylamine compounds have high glass transition temperature, can form stable and uniform amorphous form film, do not emit fluorescence with the wavelength of more than 420 nanometers and can be used in a photovoltaic conversion device as the hole-transporting material.
