      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.
