Structural color has attracted significant attention due to its durability,environmental friendliness,and high saturation.Chiral structural colors,in particular,hold great promise for advanced optical control due to their tunable polarization properties,making them ideal for next-generation optical devices.Blue-phase liquid crystals(BPLC),with their unique three-dimensional chiral structures and dynamically adjustable structural colors,have drawn considerable interest from researchers.This review summarizes the patterning strategies,responsiveness,and applications of BPLC,beginning with an overview of their concept and fundamental properties.The review first introduces the basic principles and properties of BPLC,highlighting the methods to expand their temperature range,such as polymer-polymer stabilization,molecular tuning,and inorganic material doping.Next,it explores patterning techniques for BPLC and the multiple responsive behaviors of these patterns.Key preparation methods including chemical substrate patterning,mask-based techniques,inkjet printing,direct writing and laser cutting are discussed.The responsiveness of the patterns is discussed in terms of the optical property changes and pattern transformations induced by various external stimuli,including electrical,optical,thermal,mechanical,and solvent or vapor exposure.Finally,the article discusses the optical applications of BPLC in areas such as information transmission,lasers,and sensors,while also addressing current challenges in BPLC patterning and potential future research directions.
