Small molecules based on diphenylamine and carbazole with large two-photon absorption cross sections and extraordinary AIEE properties

Two simple small molecules based on diphenylamine ( T1 ) and carbazole ( T2 ) have been synthesized for two-photon absorption materials. Both dyes exhibit extraordinary aggregation-induced emission enhancement (AIEE) properties and high corresponding quantum efficiencies of 11.5% and 16.0%. The valu...

Zusammenfassung:Two simple small molecules based on diphenylamine ( T1 ) and carbazole ( T2 ) have been synthesized for two-photon absorption materials. Both dyes exhibit extraordinary aggregation-induced emission enhancement (AIEE) properties and high corresponding quantum efficiencies of 11.5% and 16.0%. The value of the two-photon absorption cross-section for T1 is 1240 GM.
