Electron spin, the quantum of angular momentum inherent in all elementary particles, plays a pivotal role in determining the assembly or growth, as well as the multifunctional properties of matter. Zhang's research group is dedicated to advancing our understanding of the role of spin in shaping molecular framework materials, such as metal-organic frameworks (MOFs), colvalent organic framework (COFs) and spin crossover materials, and its fundamental impact on their multifunctional properties.
