We will hold an international symposium on the synthesis of structurally controlled 3D materials and their applications. We invite Prof. Pil Jin Yoo of Sungkyunkwan Univ. Korea who has won 2020 The SCEJ Award for Outstanding Asian Researcher and Engineer for the keynote speech of this symposium. We also invite domestic and foreign researchers working on the synthesis of organic polymer and organic-inorganic-highbred materials to discuss about the synthesis of structural control materials such as thin films, particles, zeolites, MOF, and the latest research trends in their application to energy devices, electronics, optical materials and so on.
