Abstract

A new series of symmetric two-photon absorbing chromophores with various л-bridges were synthesized. It has been shown that the spectra of two-photon absorption and two-photon induced fluorescence can be fined tuned by structural variations in the electronic nature and twist angle of л-bridges of D-л-D type chromophores. These chromophores exhibited large twophoton absorption cross-sections (up to 1800 GM), which were determined by two-photon induced fluorescence technique using femtosecond pulse excitation. The colors of two-photon pumped emission of these chromophores varied from blue to red (433 ∼ 604 nm) as the structure of л-bridges changed.
