Abstract: | New two-photon absorption dyes including benzophenone parts,p-N,N-diphenylamino-p'-phenacylstilbene(C1),4,4-di-(4- benzoylstyrene)yltriphenylamine(C2) and 4,4',4-tri(4-benzoylstyrene)yltriphenylamine(C3),were synthesized and characterized by ~1H NMR and elemental analysis.The ratio of the molar extinction coefficients of compounds was approximately equal to the ratio of the branch amount of the compounds,namely,C1:C2:C3 was 1:2:3.Extremely high fluorescence quantum yields were detected for these compounds.T... |
