On June 2, 2026, Assoc. Prof. Zsolt Kelemen from the Budapest University of Technology and Economics in Hungary visited the Institute of New Concept Sensors and Molecular Materials at Shaanxi Normal University, and presented a report titled “Conjugation Mechanisms and Electronic Effect Regulation in Three-Dimensional Aromatic Carboranes”.

Zsolt Kelemen’s research explores the interaction mechanisms between three-dimensional carboboranes and two-dimensional aromatic systems, revealing the pivotal roles of the hyperconjugation effect and ring strain. By further expanding the carboborane system through boron-site substitution, he demonstrates how the hyperconjugation effect can be utilized to regulate boron-boron bond lengths. He was the first to achieve aggregation-induced emission in boron-site-modified systems, providing a novel approach for the design of new carboborane optoelectronic materials.

The session was moderated by Prof. Ma Jiani. More than 30 faculty members and students from the institute attended the event and engaged in a discussion with Zsolt Kailemen.
