Abstract
New classes of nonlinear optical molecules were synthesized and characterized. It is shown experimentally that molecules with heteroaromatic π-electron systems exhibit exceptional second order nonlinear optical response and good solubility. Measurement of the nonlinear optical properties of molecules containing heteroaromatic moieties with different length scale reveals a power law dependence of Bµ on the number of π-electrons. Also, the effects of two nitro groups as electron acceptors on the aromatic ring are discussed.
