Reversible Optical Patterns from the Photoisomerization and Thermal Relaxation of Cyclosiloxane-Based AIEgens |
| 초록 |
A cyclosiloxane-based photoisomerizable AIEgen (CSPA) was newly synthesized for reversibly switchable optical patterns. The photoisomerization of CSPA in bulk easily occurs due to flexible cyclosiloxane and enough alkyl chains. The isomerization from trans to cis form induces phase transition to isotropic, which results in changes in optical properties. Reverse isomerization of CSPA can occur by thermal annealing above 200 ℃. As a result, reversible optical patterns are successfully demonstrated by reversible isomerization behaviors of CSPA.
