A set of symmetrically substituted multibranched chromophores composed of three quinoxaline-based congeners has been synthesized and experimentally shown to possess strong and widely dispersed two-photonabsorptivities in the visible to near-IR region under the irradiation of femtosecond and nanosecond laser pulses. The electronic properties of the central π bridges incorporated into the final structures
