Comprehensive Summary Block copolymers have aroused much interest, and their application has been rapidly expanded. In recent years, our group has committed to exploring synthesis and self-assembly of block copolymers. We have designed and synthesized several new thermo-responsive polymers and photo-responsive polymers by living/controlled radical polymerization (LCRP) and investigated their stimuli-responsive properties. Aiming at convenient and efficient synthesis of block copolymer nano-assemblies, we have developed several methods based on polymerization-induced self-assembly (PISA). Herein, we give a short summary of our research in these years. The aim of this account is to stimulate innovative synthesis strategies of block copolymer nano-assemblies, and promote more scientific research cooperation to face the exciting opportunities and challenges encountered in block copolymers. What is the most favorite and original chemistry developed in your research group? Thermo-responsive polymers based on dialkylamine groups may be the such thing. It is found that the dialkylamine groups especially the diethylamine group act the predominant role to the thermo-response, and based on this finding several new thermo-responsive polymers and stimuli-responsive block copolymer nano-assemblies have been synthesized. How do you get into this specific field? Could you please share some experiences with our readers? Since 2004 I got Ph.D. degree in polymer chemistry and physics from Nankai University, I began my research mainly on polymer chemistry till now. I think it the most important to focus on a topic useful in science or in practical application, which helps to maintain interest continuously. How do you supervise your students? It is a good way to discuss with students timely and deeply. What is the most important personality for scientific research? Hard work and keen interest. What are your hobbies? What's your favorite book(s)? I like flower farming and fishing. When I retire, I think I will be a good farmer. Who influences you mostly in your life? My parents. They are simple, kind hearted and hardworking.
