Optically Tunable Secret Ink by Kinetic Control of Polymorphic Superstructure |
| 초록 |
To fabricate the encryption materials with instantaneous handling of both transparency and luminescence, a monopyrene molecule with dendritic alkyl chains (MPMD) was newly designed and synthesized. As a result of the fundamental phase transition behavior by thermal and optical analysis and the microscopic structure analysis by 2D WAXD and TEM, it is identified that MPMD has polymorphic superstructures. These superstructures are regulated by the competition between π−π interaction and H-bonding. There are impressive changes in optical properties of MPMD due to the kinetic control of polymorphic superstructure. The visibility and luminescent intensity of MPMD can be tuned by external stimuli and processing methods. Optically tunable materials with transparency and luminescence caused by kinetic control of polymorphic superstructure can be an efficient way for developing secret ink.
