Abstract :
Summary form only given. The design of two-photon absorbing chromophores for applications such as optical limiting, fluorescence imaging and microfabrication, relies on the availability of detailed structure-property relationships for the two-photon response. In this presentation we will discuss the two-photon absorption spectra for donor-/spl pi/-donor (D-/spl pi/-D), donor-/spl pi/-acceptor-/spl pi/-donor (D-A-D) and acceptor-/spl pi/-donor-/spl pi/-acceptor (A-D-A) molecules (where /spl pi/ is a biphenyl, a polyenic-type or bis(styryl)benzene-type /spl pi/-bridge), which have been measured using the two-photon induced fluorescence method.
