Abstract
The ultrafast nonlinear optical properties of Polycyclic aromatic hydrocarbon (PAHs) based benzo[b]perylene derivative named as benzo[b]naphtho[1,2,3,4-pqr]perylene (BNP) are studied using femtosecond Z-scan at 800 nm. A strong three-photon absorption coefficient of 0.56×10-5 cm3/GW2 was observed.
