Abstract
Heterocyclic 1,3,4-oxadiazole moiety has been used as a new p-conjugation relay to prepare a number of donor-acceptor molecules carrying a p-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, β (14-124 × 10-30 esu) and provide the basis for future design of efficient nonlinear optical materials having the oxadiazole core.
