Abstract

A star-shaped multi-polar chromophore (1) combining functionalized indenoquinoxaline and pyridopyrazine units has been synthesized and characterized for its two-photon absorption (2PA) properties both in the femtosecond and nanosecond time domains. Under our experimental conditions, this model fluorophore is found to manifest strong and widely dispersed two-photon absorption as well as effective power-limiting/stabilization properties against long laser pulses in the near-IR region.
