Abstract: Heteroaromatic cations reacted with N-heteroarylacetylenes under Sonogashira conditions to allow easy access to potential single donor D-pi-A(+) and V-shaped D-pi-A(+)-pi-D chromophores, where the acceptor moiety A is the pi-deficient pyridinium cation and the donor moiety is represented by different p-excessive N-heterocycles. The beta hyperpolarizabilities were measured using hyper-Rayleigh scattering experiments and the experimental data are supported by a theoretical analysis that combines a variety of computational procedures, including Density Functional Theory (DFT) and correlated Hartree-Fock-based methods (RCIS(D)).
