2,4,6-Tris[(E)-2-(4-methylphenyl)ethenyl]-1,3,5-triazine is a star-shaped push-pull compound featuring a central 1,3,5-triazine core acting as an electron acceptor, with three (E)-2-(4-methylphenyl)ethenyl groups extending symmetrically from it. 2,4,6-tris[(E)-2-(4-methylphenyl)ethenyl]-1,3,5-triazine exhibits intramolecular charge transfer (ICT) due to the electron-donating nature of the peripheral methylphenyl groups and the electron-withdrawing triazine core. Protonation of the triazine core enhances ICT, leading to a bathochromic shift in absorption, while further protonation disrupts this effect. 2,4,6-tris[(E)-2-(4-methylphenyl)ethenyl]-1,3,5-triazine's absorption properties align with trends observed in similar triazine derivatives, converging to a long-wavelength limit in neutral and protonated states. Additionally, its non-centrosymmetric crystal structure suggests potential for second-order nonlinear optical applications.

Check Digit Verification of cas no

The CAS Registry Mumber 615266-53-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,5,2,6 and 6 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 615266-53:
(8*6)+(7*1)+(6*5)+(5*2)+(4*6)+(3*6)+(2*5)+(1*3)=150
150 % 10 = 0
So 615266-53-0 is a valid CAS Registry Number.

Star-Shaped Compounds Having 1,3,5-Triazine Cores

Meier, Herbert,Holst, Hans Christof,Oehlhof, Annette

, p. 4173 - 4180 (2003)

The 1,3,5-triazine derivatives 1-4 having styryl or higher oligo(phenylenevinylene) chains in the 2-, 4-, and 6-positions represent star-shaped push-pull compounds. Alkoxy or dimethylamino groups on the peripheral benzene rings, which act as electron donors, and the central 1,3,5-triazine ring, which acts as an electron acceptor, cause intramolecular charge transfer (ICT) to occur in the absorption S0→S 1. Protonation of the 1,3,5-triazine core enhances the effect, as demonstrated by a bathochromic shift; a secondary protonation on the dimethylamino groups, however, leads to the breakdown of the ICT. Thus, the yellow compound Id first becomes violet and then colorless upon the addition of trifluoroacetic acid. In neutral solution, the long-wavelength absorption of the series 1f, 2b, 3, and 4 converges to λ∞ = 427 nm (with an effective conjugation length nECL = 7). The absorption of the corresponding protonated compounds approaches λ∞ = 515 nm (nECL = 6). Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003.

Syntheses, structures and second-order nonlinear optical properties of octupolar compounds: 2,4,6-Tri-substituted s-triazine

Cui,Fang,Lei,Xue,Yu

, p. 507 - 511 (2003)

Three compounds with three p-substituted styryls attaching to the central s-triazine have been synthesized and two crystals determined to be in non-centrosymmetric Cmc21 and Pmn21 space groups, respectively. All of them in solid stat

Synthesis, photophysical properties of tribranched chromophores based on 1,3,5-triazine core and different electro- donating end-groups

Liu, Li,Huang, Wei,Shi, Jieping,Lue, Changgui,Cui, Yiping,Lu, Guo-Yuan

scheme or table, p. 2129 - 2133 (2012/03/26)

Three two-photon absorption (TPA) tribranched chromophores were successfully prepared, in which 1,3,5-triazine is been as electron deficient core, 1,4-phenylenedivinylene as conjugated bridge, 3,4-ethylenedioxythiophene (EDOT) (T1), N-methylpyrrole (T2) or triphenylamine (T3) as electron-donating end-groups. Their photophysical properties were studied by absorption, one- and two-photon fluorescence and TPA cross-section determination. The nonlinear transmission (NLT) measurement in femtoseconds (fs) regime at 800 nm indicates that TPA cross-section σ2 values of T1, T2 and T3 with extended π-conjugated bridge are much larger than the corresponding chromophore T4 with a short length bridge, and TPA cross-section of T1 with end-groups EDOT exhibits a remarkable enhancement compared with T2 and T3 having the same length π-system. The chromophores T1, T2 and T3 show also remarkable up-converted luminescence and optical limiting activity.
