“…The visible and NIR light excitation property can endow the ternary supramolecular assembly with features of higher penetrability in tissue and lower phototoxicity. 40,41 By virtue of the above functional characteristics of the ternary supramolecular assembly TP-3PY3CB[8]@SC4AD, we applied it to the targeted imaging of HeLa cells and in vivo bioimaging of mice. First, the cytotoxicity experiments of TP-3PY3CB[8]@SC4AD were evaluated by cell counting kit-8 (CCK-8) assay with HeLa cells as a model.…”

“…Considering the large aromatic domain and the symmetrical molecular structure, we were curious to know whether the triphenylamine‐based cationic macrocycle 1 possessed the multiphoton absorption ability. [ 10 ] The triphenylamine macrocycle 1∙4Cl − could form supramolecular aggregate via its π ‐conjugated skeleton, leading to the enhanced absorption properties. As expected, the fluorescence emission spectrum obtained upon excitation at 880 nm resembles the one upon excitation at 440 nm in water, indicative of the good two‐photon absorption property of 1∙4Cl − (Figure S13 , Supporting Information).…”

The optimization of molecular conformation and aggregation modes is of great significance in creation of new luminescent materials for biochemical research and medical diagnostics. Herein, a highly emissive macrocycle ( 1 ) is reported, which is constructed by the cyclization reaction of triphenylamine with benzyl bromide and exhibits very distinctive photophysical performance both in aqueous solution and the solid state. Structural analysis reveals that the 1 can form self‐interpenetrated complex and emit bright yellow fluorescence in the crystal lattice. The distorted yet symmetrical structure can endow 1 with unique two‐photon absorption property upon excitation by near‐infrared light. Also, 1 can be utilized as an efficient photosensitizer to produce singlet oxygen ( 1 O 2 ) both in inanimate milieu and under cellular environment. More intriguingly, due to the strong association of 1 with negatively charged biomacromolecules, organelle‐specific migration is achieved from lysosome to nucleus during the 1 O 2 ‐induced cell apoptosis process. To be envisaged, this conformationally confined cationic macrocycle with photocontrolled lysosome‐to‐nucleus translocation may provide a feasible approach for in situ identifying different biospecies and monitoring physiological events at subcellular level.
