Tetraphenylethylene-Functionalized Neutral Radicals for Near-Infrared Photothermal Conversion
A series of all-twisted radicals (<b>TTM-PTPEA</b>, <b>TTM-2PTPEA</b>, and <b>TTM-3PTPEA</b>) have been designed and synthesized by introducing aniline-modified tetraphenylethene onto the side arm of the TTM core. These radicals feature a near-infrared (NIR) absorption due to the efficient intramolecular charge transfer interactions. Moreover, the twisted molecular skeleton and intense intramolecular motions greatly contribute to their silent emission and photothermal conversion. Notably, <b>TTM-3PTPEA</b> containing three PTPEA units exhibits high performance with a NIR photothermal conversion efficiency of 59%.
