Dr. Yi Yan, was born in Huozhou, Shanxi province in 1983. I got my Bachelor degree of Chemistry from the College of Chemistry of Jilin University in 2006, then I pursued my PhD degree in the state key laboratory of supramolecular structure and materials, and got my PhD in polymer chemistry and physics in 2011. My PhD thesis is: dynamic self-assembly of polyoxometalate-based supramolecular complexes. I started my postdoctoral research in the Department of Chemistry, Queen''''''''s University, Canada from 2011, mainly focus on the synthesis of novel macrocyclic structure and its stimulus response binding of alkaline earth metal ions;since Nov. 2012, I started postdoctoral research on metal-contained polymer and function at the Department of Chemistry and Biochemistry of University of South Carolina at Columbia. In May 2015, he was appointed as a full professor at School of Science, Northwestern Polytechnical Univetsity.
