Popis: Heterocyclic 1,3,4-oxadiazole moiety has been used as a new \pi-conjugation relay to prepare a number of donor-acceptor molecules carrying a \pi-electron-rich aromatic ring as a donor and either a p-nitrophenyl or a pyridine/pyridinium ring as an acceptor. Several of these oxadiazoles display significant second-order molecular nonlinearity, $ \beta (14-124 x 10^{-30} esu)$ and provide the basis for future design of efficient nonlinear optical materials having the oxadiazole core.
