Abstract
We demonstrated for the first time without any chemical modification the two-photon absorption (TPA) cross-section can be enhanced and red-shifted to the near-infrared (NIR) region by the ground-state proton-transfer (GSPT) process. Using GSPT, we developed a simple binol-based aggregation-induced emission (AIE)-fluorogenic phototrigger having a large two-photon uncaging cross-section in the "phototherapeutic window". As a proof of concept, we showed our phototrigger for the release of two different anticancer drugs in the NIR region.
