Magnetic-Directed Assembly from Janus Building Blocks to Multiplex Molecular-Analogue Photonic Crystal Structures
The predictable assembly of colloidal particles into a programmable superstructure is a challenging and vital task in chemistry and materials science. In this work, we develop an available magnetic-directed assembly strategy to construct a series of molecular-analogue photonic crystal cluster particles involving dot, line, triangle, tetrahedron, and triangular bipyramid configurations from solid-liquid Janus building blocks. These versatile multiplex molecular-analogue structural clusters containing photonic band gap, fluorescent, and magnetic information can open a new promising access to a variety of robust hierarchical microstructural particle materials.
