AbstractAggregation-induced emission nanoparticles serve as promising fluorescence probes for multi-photon excitation microscopy due to the large absorption cross-section at NIR-IIb region. Here we present organic AIE nanoparticles that feature high aborption cross-section under three-photon excitation. We show that these enable ultra-deep NIR-IIa excited three-photon imaging in the in-vivo mouse brain.

Emission Enhancement

Two simple small molecules based on diphenylamine (T1) and carbazole (T2) have been synthesized and characterized. Both dyes exhibit extraordinary aggregation-induced emission enhancement 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.
