Abstract

(matrix presented) The synthesis and nonlinear optical characterization of two novel heteroaromatic-based chromophores is described. The new dyes present an A-π-D-π-A general framework, where A is a π-deficient heteroaromatic ring (pyridine, quinoline, benzothiazole) and D a π-excessive pyrrolyl moiety. Both systems exhibit large two-photon absorption (TPA) values in the femtoseconds regime (TPA cross section as high as 150 x 10^-50 cm⁴ s photon^-1 molecule^-1 with 150 fs laser pulses). Their TPA-based optical limiting activity is also shown.
