Fluorodynamers displaying tunable fluorescence on constitutional exchanges in solution and at solid film-solution interface.

Fluorodynamers displaying tunable fluorescence on constitutional exchanges in solution and at solid film-solution interface. Chemistry. 2020 Mar 27;: Authors: Si M, Zhu W, Zhang Y, Barboiu M, Chen J Abstract Dynamic covalent polymers -the dynamers- are adaptive materials that offer timely variant adaptive macroscopic organization across extended scales. In the current study, imine exchange reactions and fluorescence transfer can occur at the interfaces between various solutions and solid state dynameric films. The fluorescence quenching upon imine formations for designed fluorogen was successfully demonstrated, and this tunable fluorescence was further used to study the re-composition of a solid film. Moreover, the dynamic covalent films also exhibited responsiveness to competing amines and acid/base conditions, both in solutions and solid film-solution interface. This work can provide more insights into interface dynamic chemistry and hold great potentials for further applications in optical and biomedical materials.
