Aqueous up-conversion organic phosphorescence and tunable dual emission in a single-molecular emitter.

ABSTRACT: Materials exhibiting up-conversion room-temperature phosphorescence (RTP) with multi-emissive properties in aqueous solutions hold significant potential for optical imaging and sensing applications. However, achieving such photophysical materials within a molecular emitter remains a formidable challenge. Herein, we report a series of single-molecule chromophores demonstrating aqueous tunable up-conversion RTP and fluorescence dual emission. The RTP and fluorescence emission could be finely adjusted by manipulating the excitation wavelength within the visible and near-infrared range, enabling dynamic color modulation across the entire visible spectrum from blue to orange-red. Furthermore, we utilized the up-conversion RTP capability of a single-molecular emitter to achieve two-photon and ti
