Unveiling the Key Templates in the Self-Assembly of Gigantic Molybdenum Blue Wheels

Autor: Leroy Cronin, De-Liang Long, Nancy Watfa, Qi Zheng, Robert Pow, Weimin Xuan

Template synthesis is a powerful and useful approach to build a variety of functional materials and complicated supramolecular systems. Systematic study on how templates structurally evolve from basic building blocks and then affect the templated sel
