Multifunctional optical diffusers based on hybrid polysiloxane@CeO 2 @PMMA microspheres were successfully prepared by UV curing process. The novel diffusing microspheres can be synthesized via facile one-pot method, and their structure was characterized by FT-IR, TEM, SEM, XRD, and TGA. The diffusers based on polysiloxane@CeO 2 @PMMA were found to have better properties such as heat resistance, mechanical, UV-shielding, fluorescence, and anti-aging ability compared to the diffusers using organic diffusing microspheres. Moreover, the new diffuser exhibited a strong NIR absorption, which had a potential application in absorbing materials and night vision LCD monitor products. In addition, a good diffusing effect was achieved using the new diffuser, and the light-diffusing mechanism was also illustrated. Moreover, the anti-aging ability of diffusers can be gradually improved with the increasing concentration of polysiloxane@CeO 2 @PMMA fillers. The novel diffusers based on polysiloxane@CeO 2 @PMMA possessed a stronger resistance to UV aging compared to moist-heat aging.Hence, this study firstly introduced hybrid microspheres to optical diffusers, which can be used for preparing different multifunctional diffusing materials such as touch-panel functions, monitors, military projectors, and novel LCDs. † Electronic supplementary information (ESI) available: The synthesized details of polysiloxane@CeO 2 @PMMA are presented. Then, the physical and chemical properties of multifunctional microspheres of polysiloxane@CeO 2 @PMMA were examined by FT-IR, powder transmission electron microscopy (TEM), Scanning Electron Microscopy (SEM), X-ray diffraction (XRD).

Aryl diazonium salts are important molecules in organic chemistry. This review discusses advances of their application in light‐mediated reactions summarized in five categories according to the bond formations: (1) C−C formation from alkenes, alkynes, arenes, isocyanide, CO, arylboronic acid, or Grignard reagent. (2–5) C−B, C−N, C−S, and C−P formations. Reactions such as radical addition, elimination, metal‐catalyzed coupling, C−H activation, cyclizations, and rearrangements will be discussed herein.

ZnO@polysiloxane hybrid microspheres were successfully prepared by a simple one-pot synthesis. The novel diffuser based on ZnO@polysiloxane fillers possessed suitable light transmittance, good diffusion capacity, and low incident angle dependence.
