We report on the absorption, fluorescence, and two-photon excitation spectra of a series of 5-phenylisoindolo[2,1- a ]quinoline dyes. Depending on the substituents, we observed increasing two-photon absorption cross sections, with values up to 56 GM@973 nm, which are similar to those of the enhanced green fluorescent protein and fluorescein, common fluorescent chromophores.
