In the afternoon of October 13, 2022, Professor Wang Xun from the Department of Chemistry of Tsinghua University was invited by Professor Huang Hui to give a lecture on " Sub-1nm Ultrathin Nanocrystals " at the University of Chinese Academy of Sciences.

As research in nanoscience continues to advance, more and more research is now focused on the bottom end of the "nanoworld": the scale of one nanometer or so or even one nanometer below, which is defined as "sub-nanometer" scale materials.

Polymeric materials are widely used because of their flexibility and good processing characteristics. However, inorganic materials tend to be hard and brittle in mechanical processing due to the composition of polar bonds, which limits the practical application of the materials to some extent. Prof. Wang Xun started with the inorganic nanowires in their previous work. They found that these inorganic nanowires have certain properties of polymer materials, so Wang Xun's group took this as a starting point and used electron microscopy to observe that the nanowires have very obvious structural flexibility, the skeleton can be bent in all directions arbitrarily, and even self-winding to form closed rings; and the dispersion of this nanowire has a polymer solution with After that, Prof. Wang Xun's group extended the system and discovered a wide range of properties of sub-nanomaterials. They then investigated two-dimensional and clustered sub-nanomaterials and found that these materials have good mechanical and electrochemical properties, greatly expanding the applications of sub-nanomaterials. After the presentation, Prof. Wang Xun received a warm applause from the students and faculty.

Selenium/tellurium-containing polymer materials have gained widespread attention in recent years due to their potential for applications in self-healing, shape memory, information storage, optical programming materials, and medical materials.

In his lecture, Prof. Huaping Xu gave a clear and organized introduction to the history of the development of selenium/tellurium-containing polymer materials. Firstly, the unique bond energy of C-Se bond determines its unique dynamic responsiveness. The team synthesized various Se containing polymer materials and found that these materials have unique dynamic responsiveness. Then atomic force microscopy was used to test the chain-breaking energy and explain why the Se containing polymer materials are dynamically responsive from the bond energy perspective. He also introduced the applications of Se/Tellurium-containing polymer materials in various fields such as self-healing, shape memory, information storage, optical programming materials, hydrophobic materials, and medical materials. Finally, Prof. Xu Huaping exchanged and discussed with the students and teachers on site, which received enthusiastic responses from them.

      Professor Pei Jian pointed out in his report that organic electronic materials, especially organic semiconductor materials, have a wide range of applications in life and industry. In order to improve the performance of organic semiconductor devices, scientists use molecular doping to control the carrier concentration of organic semiconductor devices. and the Fermi level, filling its carrier traps and improving the electrical conductivity of the material, thereby achieving a significant improvement in the performance of organic semiconductor materials. To accomplish molecular doping of organic semiconductor devices, the properties of molecular dopants are particularly critical. A variety of new n-type dopants have been designed in view of the two problems existing in the existing n-type dopants: the counter-ion becomes an impurity that hinders charge transport and the phase separation of the dopant and the semiconductor is caused by poor miscibility.

      Prof. Pei Jian introduced the research progress of his research team in designing n-type dopants through organic negative hydrogen compounds, from doping mechanism, negative hydrogen mechanism, molecular design, electron-deficient framework system, synthesis route, performance characterization and industrialization. Excellent results have been achieved in applications and other aspects, and thermally excited doping, highly miscible TAM and N-heterocyclic carbene dopants have been introduced. At the end of the report, Professor Pei Jian also briefly introduced a variety of new n-type dopants, and predicted the future development trend of this field.

      In the Q&A session of the report, the teachers and students of the National Academy of Sciences and Professor Pei Jian conducted in-depth exchanges and discussions on academic and scientific research issues such as doping mechanism characterization, design principles of n-type dopants, and development of carbene dopants. The atmosphere was warm and the lecture ended successfully with warm applause.
