Carbon Dot‐Incorporated PMO Nanoparticles as Versatile Platforms for the Design of Ratiometric Sensors, Multichannel Traceable Drug Delivery Vehicles, and Efficient Photocatalysts

Using silylated carbon dots as the framework fluorogen, periodic mesoporous organosilica (PMO) nanoparticles (NPs) possessing unimpeded, ordered meso­pores, and excellent one- and two-photon excitation fluorescence properties are obtained. These novel, fluorescent NPs serve as platforms for the design and fabrication of ratiometric sensors, multichannel traceable drug delivery vehicles, and efficient photocatalysts.
