Quinoline-derived two-photon sensitive quadrupolar probes

The first quadrupolar 8-dimethylaminoquinoline-derived 6-(8-DMAQ-OAc)2 (1c) and 5-(8-DMAQ-OAc)2 (2c) photosensitive probes underwent photolysis under UV (365 nm) and NIR (730 nm two-photon (TP)) irradiation conditions, showing Qu = 9.3% and 6.6% quantum yields and δu = 0.07 GM and 0.40 GM uncaging cross-sections, respectively.
