Absorption, Fluorescence, and Two-Photon Excitation Ability of 5-Phenylisolidolo2,1-aquinolines

摘要

We report on the absorption, fluorescence, and two-photon excitation spectra of a series of 5-phenylisoindolo2,1-aquinoline dyes. Depending on the substituents, we observed increasing two-photon absorption cross sections, with values up to 56 email protected nm, which are similar to those of the enhanced green fluorescent protein and fluorescein, common fluorescent chromophores.
