| Abstract: | Three trisubstituted imidazoles were synthesized and approved by means of ^1H NMR, mass spectrometry and elemental analysis. Their linear absorption spectra and single-photon induced fluorescent spectra were measured. It was found that they have large two-photon cross-section and also have very high quantum yields. |

| Keywords: | two-photon absorption triphenylimidazole derivatives structure-activity relationship |
