As an emerging soft 3D photonic material, blue phase liquid crystals have attracted growing attention and research. They can self-assemble into a 3D photonic nanostructure with periodic cubic lattices and has excellent optical properties. Such as no birefringence, fast response speed and selective reflection. Stimulus-responsive 3D nanostructures and dynamic control of their photonic band gap in the visible spectrum are one of the most interesting fields in blue phase research, especially the research on photo-responsive blue phase liquid crystals have received extensive attention. Compared with other stimulus-responsive liquid crystals, it has excellent characteristics such as remote controllability, accuracy and transientness. This paper mainly reviews the discovery and structural characteristics of blue phase liquid crystals, and introduces in detail the research advances and application status of photo-responsive blue phase liquid crystals at home and abroad in recent years.
