AbstractLead halide perovskite nanocrystals were prepared and used as photocatalysts for the in situ 1O2 generation to perform hetero Diels–Alder, ene and oxidation reactions with suitable dienes and alkenes. The methodology has been reasonably standardized and made applicable to a variety of olefinic substrates. The scope of the method is finely illustrated by the results in all the tested reactions, which allowed to obtain desymmetrized hydroxy-ketone derivatives, unsaturated ketones and epoxides. Some limitations were also observed especially in the case of the alkene oxidations as well as poor chemoselectivity was somewhere observed.

Abstract Mn-doped CsPbCl3 perovskite nanocrystals (PeNCs) glass was prepared by melt-quenching and in-situ crystallization. Under the protection of robust glass, PeNCs exhibit excellent moisture resistance and thermal stability. Due to the combination effect of thermal quenching and energy transfer of exciton-to-Mn2+, the emission intensity of Mn shows an abnormal temperature-dependence with the temperature increasing from 80 to 300 K, which can be explored further in the application of temperature sensor. Interestingly, by matching with ultraviolet chips, all-inorganic blue-red emitting conversion device consisting of PeNCs glasses were prepared for light-emitting diodes (LEDs), which can meet the light requirements of plant growth. The cultivation results indicated that growth of cabbages using PeNCs plant cultivation LEDs were greater than those cultivated using commercial w-LEDs. Therefore, Mn-doped CsPbCl3 PeNCs can be used as a new-generation of solid fluorescent materials in the field of indoor plant cultivation LEDs.
