Abstract
⺠The optical nonlinearity of HBI was investigated for the first time. ⺠The nonlinear absorption was confirmed to originate from TPA. ⺠By establishing ESIPT kinetic model, the TPA cross section was obtained. ⺠The HBI molecules exhibit much larger TPA cross section than other similar structural ones. ⺠The high nonlinearities were interpreted on the basis of the nonlinear optical molecular design and their origin.
