Review demonstrates photochromic switching and cyclization properties in diarylethenes, highlighting their potential for rewritable optical memories and nanoscale molecular devices.

Key Points

To review the design, photochromic mechanisms, and functional properties of diarylethene derivatives for use in optical data storage and molecular electronics.
Analyzed photoinduced reversible cyclization and cycloreversion reactions of diarylethene derivatives upon light irradiation.
Evaluated structural factors controlling thermal stability, absorption spectra changes, quantum yields, and fatigue resistance across repeated switching cycles.
Diarylethenes with heterocyclic aryl rings exhibit thermally irreversible photochromism, preserving both open-ring and closed-ring isomers across wide temperature ranges.
Structural modifications suppress unwanted conformation states, enabling high photocyclization quantum yields and durability exceeding thousands of switching cycles without degradation.
