Abstract:	A new multi-branched fluorophore derived from tetra-quinoxalinylethylene as the core with diphenylaminofluorene units incorporated at the peripheral positions has been synthesized via Pd-catalyzed Suzuki coupling and experimentally shown to possess strong solvent effect on its fluorescence emission and lifetime behaviors. The initial characterization also found that this dye molecule exhibits two-photon activities and effective optical power limiting properties in the near-IR region under the irradiation of nanosecond laser pulses.
