文摘

•: Opal-like array of polystyrene (PS) microspheres is synthesized by self-assembly.
•: This periodic PS array is used as a rapid sensor for methanol and ethanol.
•: Solvents are detected by routes of reflection coordinates in chromaticity diagram.
•: They are also detected directly by naked eye based on change in color of sensor.
•: The color change is irreversible for methanol but reversible for ethanol.
