Synthesis and properties of aza analogs of merocyanine dyes based on N-substituted 2- and 4-aminopyridinium salts

A series of aza analogs of the merocyanine dyes based on 1-N-alkyl-2- and 1-N-alkyl-4-aminopyridinium salts and ethoxymethylidenemalononitrile was synthesized. Their physico-chemical properties were studied.

Effect of intercalation and chromophore arrangement on the linear and nonlinear optical properties of model aminopyridine push-pull molecules

Three push-pull aminopyridine derivatives having D-π-A, D-(π-A)2, and D-(π-A)3 arrangements were examined as model organic chromophores capable of intercalation into inorganic layered materials (alpha modification of zirconium hydrogen phosphate, zirconium 4-sulfophenylphosphonate, and gamma modification of titanium hydrogen phosphate). The fundamental properties of these dyes, their methylated analogues as well as their intercalates were studied by X-ray analysis, electrochemistry, UV/Vis absorption spectra, TGA, IR spectra, SHG, and were completed by DFT calculations. The synthesis of tripodal tris(pyridin-4-yl)amine is given for the first time. The HOMO-LUMO gap, the position of the longest-wavelength absorption maxima, and the dipole moment of aminopyridines can easily be tuned by attaching/removing pyridin-4-yl electron withdrawing units and their quaternization (pyridine vs. pyridinium acceptors). Their intercalation proved to be feasible affording novel inorganic-organic hybrid materials. The intercalation is accompanied by protonation of the guest, which enhances its ICT and strongly anchors the aminopyridines into the confined space of the layered host. Moreover, this process results in ordering of the organic chromophores and also brings improved thermal and chemical robustness. As a result, the measured SHG efficiencies of the intercalates are larger than those observed for the pure organic push-pull chromophores. Hence, the methodology of intercalation turned out to be very useful strategy for property tuning of NLO-active organic molecules.

Second-order hyperpolarizability of pyridinium cations

The second-order hyperpolarizability (β) of pyridinium cations with cutoff (λco) shorter than 400 nm were studied by semiempirical calculation and the hyper-Rayleigh scattering (HRS) technique. The β value of 4-dimethylaminopyridinium (λco= 390 nm) was evaluated to be about 1.5 times larger than that of p-nitroaniline (λco= 473 nm) in methanolic solution using 1064 nm light as a fundamental beam.
