A sp3 C[sbnd]H bond functionalization and C[sbnd]C bond cleavage were realized by AIBN/O2 catalyst system, providing a series of benzophenones under mild reaction conditions. The mechanistic study shows that a peroxide intermediate is involved in this transformation, and in the case of diphenylmethanes, the sp3 C[sbnd]C bond is cleaved through the peroxide rearrangement, which might provides a new way to cleave relatively strong C[sbnd]C bond and be applied to more general C[sbnd]C bond activation.

The invention provides an organic white light material with the terminal activation delay and aggregation-induced emission performance and a synthetic method and application thereof. The general molecular formula of the white light material is Ar-Ar1-Ar2, wherein Ar is a phenothiazine electron-donating substituent group, Ar1 is a strong electron-withdrawing group, and Ar2 is an aromatic fused ring or heterocyclic aromatic substituent group except phenothiazine. The synthetic method of the material is simple, the thermal performance, luminous efficiency and white light color purity of an end product can be adjusted through connection of different aromatic fused ring or heterocyclic aromatic groups, the white light material has the thermal activation delay and aggregation-induced emission properties, the glass transition temperature is high, and the emission performance is excellent. The obtained white light material is a light emitting layer applied to preparing a non-doped OLED device, the illumination brightness is high, the stability is good, and the practicability requirement can be met.
