Synthesis, photophysics and nonlinear optical properties of stilbenoid pyrimidine-based dyes bearing methylenepyran donor groups.

Lalevée, Development of new high performance visible light photoinitiators based on carbazole scaffold and their applications in 3D printing and photocomposite synthesis,

TD-DFT calculations correctly reproduce changes in the phosphorescence energies for the helicene-based Re-NHC complexes versus the models lacking the helicene unit, and the

Figure 29: Pyrimidine chromophores 48 and 49 with optical power limiting properties Other 3rd order NLO properties As mentioned before, the nonlinear refractive index γ can be

One key conclusion drawn from these experimental evidences is that the second two-electron oxidation process (wave (b) on Figure 4B) most probably involves a

Relatively high NLO response (µ β ) have been obtained and the following trends have been observed: the multisubstitution of the triphenylamine core results in

It should be noted that for compound 6d, for a concentration of TFA = 10-2 M and even more for a concentration of TFA = 10-1 M, absorption band is red-shifted probably due to the

The vinylene-based octupole 7, which shows the largest TPA cross-sections of the two novel series, is compared in Table 3 to six three-branched compounds (Figure 1) all based on

Such an absorption at long wavelength is relatively unusual for push-pull dyes comprising TCF as the electron acceptor and an absorption in this region was only reported
