A collaborative research team, led by NSRRC scientist Dr. Wei-Tsung Chuang and user Prof. Yeo-Wan Chiang in Materials and Optoelectronic Science at National Sun Yat-Sen University, used TLS 23A1 and TLS 01C2 of the NSRRC to conduct research on bioinspired artificial optical crystal materials. Their latest findings were published in Journal of Materials Chemistry C and were highlighted with an illustration on the inside front cover of the issue.
Helical nanostructures are fascinating subjects in physical, chemical and biological fields, but the fabrication of three-dimensional helical structural templates of metamaterials at submicron scale is still a tricky issue. Their structures are too large to be made by molecular synthesis, and also too time-consuming to process by top-down approaches. On the other hand, the bottom-up strategy offered by self-assembly block copolymers requires synthesis of ultrahigh molecular weight with monodispersion in chiral blocks, and the control of twisting power of helices is a big challenge.
