dc.description.abstractThree novel triazine derivatives, (E)-4-(2-(4,6-dimethyl-1,3,5-triazin-2- yl)vinyl)- N,N-di-p-tolylaniline (a), 4,4′-((1E,1′E)-(6-methyl-1,3, 5-triazine-2,4-diyl) bis(ethene-2,1-diyl))bis(N,N-di-p-tolylaniline) (b), and 4,4′,4′′-((1E,1′E,1′′E)-(1,3,5- triazine-2,4,6-triyl)tris(ethene-2,1-diyl))tris(N,N-di-p-tolylaniline) (c), were designed and synthesized. Their photophysical and photochemical properties were investigated systematically including single-photon absorption, nonlinear optical absorption (NOA) and up-converted fluorescence. Interestingly, the compound a with single branch showed pure three-photon absorption phenomenon, while the corresponding b and c indicated two-photon induced excited-state absorption properties, showing strong structure-dependence relationship. The results offer a method to design and synthesize organic molecules for multiphoton materials. It was noted that the three-photon cross-section value (δ 3) of a was up to 1.35 × 10 -76 cm 6 s 2. Correspondingly, the two-photon (δ 2) and excited-state cross-section (δ e) values of b and c also were obtained, and value of them were 485 GM and 1.03 × 10 -17 cm 2 for b, and 1100 GM and 1.27 × 10 -18 cm 2 for c, respectively. © 2012 Elsevier Ltd.
