Graphical Abstract

Abstract

Organic electronics is an emerging field of research with interdisciplinary approaches. The primary aims of the current organic electronics research are centred around combating the obstacles faced by existing silicon-based semiconductors in microelectronics, resolving the energy crisis, and realizing flexible and wearable micro-detection device. Currently, tremendous progress has been made in the field of organic optoelectronics. The performance of these materials, however, are still inferior to their inorganic counterparts, thus limiting their practical applications.

We are primarily involved in research works pertaining to π-conjugated materials and their applications in photoelectric conversion. In the field of organic photovoltaics, aggregated structure is precisely adjusted, and the charge transmission performance is improved through modifications in the topological structure of the perylene diimide multichromophore, achieving the highest power conversion efficiency of perylene diimide-based nonfullerene acceptor material. In the field of perovskite photovoltaics, the short life and high cost of perovskite solar cells is addressed through the design of a spiro-ring system substituted by thiophene terminal groups. A series of cheap, stable and efficient small molecule charge transport materials have thus been successfully developed, achieving the record high power conversion efficiency and thermal stability for small molecule charge transport materials. We also seek to use the newly self-proposed concept of πOF (non-covalent π-Stacked Organic Framework) to create a novel multifunctional supramolecular organic porous crystal material system. Its application in organic electronics will also be explored to further new breakthroughs in the device performance and stability.
