donor-pi-donor derivatives containing phenyl, naphthyl, and anthryl groups as the pi-center and heterocyclicrings as the conjugation bridge have been synthesized and their one- and two-photon spectroscopic properties and photostability were determined. These compounds show bathochromic shifts in the absorption and emission spectra, larger two-photon cross-section, and enhancedphotostability in comparison to
