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

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.

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

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.
