My research interests

Key words: NHC catalysis, radical chemistry, cascade reaction, asymmetric catalysis, photocatalysis
My research interests focus on the development of N-heterocyclic carbene (NHC)-catalyzed, or visible light-mediated novel radical transformation, cascade reactions and asymmetric catalytic reactions. Particularly, we aim to develop efficient and highly selective catalytic transformation of aldehyde or carboxylic acid derivatives (such as carboxylic acid, ester, acyl fluoride, or amides) accessing value-added chemicals. 

10 Facts about me

When I was a kid, I wanted to be a scientist, as I enjoy new discoveries and challenges.

I published my first academic article in 2015 during my PhD studies in Nature Communications. This article demonstrates interesting and unpredictable N-centered radical addition to alkyne-initiated cascade transformations realizing animative muti-functionalization of alkynes.

The most challenging work about my research is to realize efficient asymmetric induction in NHC-catalyzed radical–radical cross-couplings.

In my spare time, I enjoy reading online novels.

My favorite science fiction novel is The Three-Body Problem.

The person who has had the greatest influence on my research career is my M.S. and Ph.D. supervisor Prof. Qian Zhang (Northeast Normal University). She was passionate about scientific research and was very inspiring.

The most important qualities of a role model are honesty, patience, and responsibility.

The most important thing I have learned is that opportunities are for those who are prepared.

I advise my students to keep enthusiasm and individual thinking about their research.

I lose track of time when discussing research progress and prospects with students.

  Advances in circularly polarized electroluminescence based on chiral TADF-active materials  

 

This review summarizes the development status of chiral TADF-active materials with CPEL, covering chiral perturbed TADF molecules, intrinsically chiral TADF molecules, and TADFsensitized fluorescent enantiomers.

My research interests

Key words: organic synthesis, circularly polarized luminescence, organic light-emitting diodes
Meng Li’s research focuses on developing chiral optoelectronic materials for photoelectric conversion devices. He is also interested in understanding the structure–activity relationship between chiral molecules and their circularly polarized luminescence properties, as well as developing circularly polarized organic light-emitting diodes for display device of low power consumption. 

10 Facts about me

My favourite published academic article is the one on circularly polarized electroluminescence (CPEL) materials in Angew. Chem. Int. Ed. in 2018. In this work, we created a new system of CPEL materials based on chiral thermally activated delayed fluorescence (TADF) materials, providing an original research idea to solve the key problem of low device efficiency in the field of CPEL materials.

The academic group that helped me most is the Youth Innovation Promotion Association CAS. The members of this academic group are all outstanding young scientists under the age of 35 in CAS. They are active in various academic fields, and are ready to help others. Becoming a member of the group has greatly helped my scientific research.

The most important questions to be asked/answered in my research field include: (1) How to design and construct chiral luminescent materials with large asymmetry factor and high efficiency? (2) How to realize the transfer, amplification and regulation of chiral optoelectronic properties with multi-level chiral structures? (3) How to realize the creation of high-performance circularly polarized light emitting devices?

The most challenging work about my research is the application of chiral luminescent materials. I think this will require interdisciplinary collaborations between different academic fields, partnerships with industrial stakeholders, etc.

If I were not a scientist, I would be a secondary school teacher.

In my spare time, I enjoy reading biographical novels and playing Chinese chess.

One piece of career-related wisdom I would like to share with other early career scientists: be passionate about your research, and keep your curiosity.

The next big goal of my research is to improve the asymmetry factor of circularly polarized electroluminescence of chiral TADF-active materials.

My favourite book is Journey to the West.

My favourite time of the day is on the way to work in the morning. At that time, I am full of expectations for the whole day’s experiments.
