A series of symmetrically substituted multi-polar chromophores (1–3) based on the skeleton of bisarylacetylene using functionalized quinoxaline, indenoquinoxaline, and pyridopyrazine moieties as the aryl substituents has been synthesized and characterized for their two-photonabsorptionproperties using femtosecond laser pulses as the probing tool. Under our experimental conditions, these model fluorophores
