TPE-TPA-FN is a type of luminogens with AIE(aggregation-induced emission) feature.1 It has extended π-conjugation,which makes it possess large nonlinear optical(NLO) effects,as well as emit far red/NIR light upon excitation.2 We studied the high-order NLO effects of TPE-TPA-FN in three different systems,which are mono-molecule in organic solution,nanoaggregates in aqueous solution,and solid state on glass slide.In chloroform/toluene mixture,three-/four-photon luminescence(3PL/4PL) of TPE-TPA-FN could be observed.
