The application discloses a method for degrading polylactic acid to obtain menthyl lactate, and belongs to the technical field of depolymerization and recycling of high polymer composite materials. The polylactic acid is degraded to become menthyl lactate in a targeted manner. In the application, the polylactic acid is dissolved in an organic solvent or without adding other solvents under the catalysis of a metal amide catalyst and in the protection of inert gas under normal pressure, and the polylactic acid is depolymerized under the action of menthol. The polylactic acid molecular chain is depolymerized under mild conditions, and the obtained menthyl lactate can be directly reused, so that the industrial production steps and industrial cost are reduced, and the sustainable development principle is met.

The application discloses a synthesis method of bifenzhydrylamine intermediate, and relates to the technical field of organic synthesis. The synthesis method comprises the following steps: taking 4-methoxy aniline as a starting material, and obtaining 4-methoxy benzene diazonium salt through a diazotization reaction; decomposing the 4-methoxy benzene diazonium salt to form an aryl free radical, adding a certain amount of benzene to carry out a coupling reaction, and obtaining 4-methoxy biphenyl; then carrying out halogenation reaction on the 4-methoxy biphenyl through a halogenating reagent to obtain 4-methoxy-3-halogen biphenyl; finally, adding a metal amide to carry out nucleophilic substitution, and obtaining 4-methoxy-3-amino biphenyl. The synthesis method of 4-methoxy-3-amino biphenyl provided by the application avoids relatively dangerous and harsh reactions such as nitration reaction and Grignard reaction, the reaction process is relatively safe, raw materials are cheap and easy to obtain, the reaction yield is high, the reaction condition is mild, the synthesis route is short, the equipment investment is small, and the method is easy to industrialize.

This article describes metal complexes and their preparation and use. In some forms, metal complexes contain C NHC ^C^C NHC (NHC=N-heterocyclic carbene) clamp ligands with a through-bonded donor-acceptor configuration. The donor (e.g., an amide group) is coordinated to a metal ion, while the acceptor (e.g., 2,4,6-triphenyl-1,3,5-triazine and its derivatives) is incorporated into the clamp ligand and located at the para position of the carbanion. In some forms, the incorporation of the acceptor (e.g., 2,4,6-triphenyl-1,3,5-triazine and its derivatives) can be applied to clamp ligands N^C^N and / or C^C^N, wherein in the metal complex, C... NHC ^C^C NHC ligand donor C NHC It can be replaced with a neutral N- donor and / or a carbanion. The design of the metal complexes disclosed herein can lead to improved photophysical properties, such as a shortened emission lifetime and / or an increased radiative decay rate constant, thereby improving their device performance in OLED devices.
