Combined Features

Non-substituted and alkyl-substituted triphenylamine–dibenzo[a,c]phenazine adducts (Q1–Q3) showed the combined features of ICT plus AEE, while the alkoxy-substituted Q4–Q5 exhibited obvious AIE effects.

A small-molecule with a large two-photon absorption cross-section serves as a membrane-permeable ribonucleic acid (RNA) probe for live cell imaging
