A series of 4-dihydroquinolinone derivatives with planar push-pull structure were synthesized including 1-benzyl-2,3-dihydroquinolin-4-one (BDHQ), 2-(2,3-dihydroquinolin-4(1H)-ylidene)malononitrile (DHQM), 1, 6-diketojulolidine (DKJ) and 1, 6-bisdicyanomethylene julolidine (BDCJ). The absorption spectra, one-photon excited fluorescence and two-photon excited fluorescence spectra have been recorded. The derivatives show strong solvatochromism in both their one-photon and two-photon excited fluorescence, sug-gesting great polarity of their excited states. Pumped by femtosecond laser at 800 nm, strong up-conversion emissions in the solution of CH2Cl2 have been observed. Their two-photon absorption cross-sections ob-tained by nonlinear transmission method are in the range of 0.83~23.95×10-50 cm4•s•photon-1. The in-tramolecular charge state upon excited state makes the dominant contribution to the two-photon absorption and two-photon excited fluorescence of theses compounds.

Key words: 1,2,3,4-tetrahydroquinolin-4-one, two-photon excited fluorescence, two-photon absorption, push-pull structure
