Prof. LOH Kian Ping, Chair Professor of Materials Physics and Chemistry and Global STEM Professor of the Department of Applied Physics of PolyU (left), Dr Kathy LENG, Assistant Professor (right), and Dr Hwa Seob CHOI, Postdoctoral Research Fellow (back) of the same department, has successfully solved an age-old challenge to synthesize all-organic two-dimensional perovskites.
Prof. Loh (right) and Dr Choi (left) discovered a new method to make 2D all-organic perovskite and named it the “Choi-Loh-v phase” (CL-v).
Prof. Loh Kian Ping, Chair Professor of Materials Physics and Chemistry and Global STEM Professor of the Department of Applied Physics of PolyU, led a team in the successful synthesis and device fabrication of all-organic 2D perovskites, solving an age-old challenge.

Perovskite materials have excellent photoelectric properties that can be applied in wide-ranging fields such as solar cells, lighting and catalysis. PolyU Science research team led by Prof. Loh Kian Ping, Chair Professor of Materials Physics and Chemistry and Global STEM Professor, Dr Kathy Leng, Assistant Professor of the Department of Applied Physics, together with Dr Hwa Seob Choi, Postdoctoral Research Fellow and the first author of the research paper, have successfully synthesized a new class of 2D all-organic perovskites, signifying a breakthrough into a new field of 2D materials.
The 2D all-organic perovskites offer distinct advantages over their all-inorganic counterparts, as they are solution-processible and enable cost-effective fabrication. These developments opened up new possibilities for the creation of more efficient electronic systems and were published in the prestigious journal Science.
