Photoactive Functional Soft Materials (Preparation, Properties, and Applications) || A Photoresponsive Multi-Bilayered Film for a Tunable Photonic Crystal

摘要： Over the last half‐century, advances in science based on the evolution of semiconductor physics and transistor electronics have greatly influenced the development of our lives. The key to this was the ability to design crystalline materials that tailor the conduction properties of electrons to suit diverse applications. More recently, the optical communication revolution has shifted the frontier in high‐speed, multiplex, and wide‐bandwidth information processing from electrons to photons, a shift that demands a new kind of synthetic soft material to mold the gigabits. To address this need, recent research has suggested a way to tailor the propagation of light much like that of electrons, via the creation of periodic optical media dubbed photonic crystals (PCs).
