Photothermal conversion and working mechanism of iMIPT NPs. a IR thermal images of various NPs in aqueous solution (100 μM based on 2TPE-2NDTA, 2TPE-NDTA and the repeat unit of semiconducting polymer) upon exposure to 808 nm (0.8 W cm−2) laser irradiation for different times. b The temperature changes of solutions of various NPs as a function of time. The solutions were irradiated with 808 nm laser (0.8 W cm−2) for 300 s followed by naturally cooling for another 300 s. c The sketch map of working mechanisms of AIE and iMIPT
