AI Technical Summary
Existing stimulus-responsive covalent organic framework (COF) materials are still limited in multi-mode detection, especially lacking materials that can produce tunable fluorescence responses to solvent environment, viscosity changes and external pressure. Moreover, existing materials are difficult to achieve dynamic conformational changes while maintaining framework crystallinity and structural stability.
By introducing aldehyde building blocks of the vibration-induced emission (VIE) active unit DPAC structure and reacting them with tetrahedral amino monomers, a covalent organic framework material with an ordered three-dimensional structure is constructed. This maintains the crystallinity and structural stability of the framework while retaining the ability to adjust dynamic conformation, thus achieving a tunable fluorescence response to external stimuli.
It achieves a significant fluorescence response to various external stimuli such as solvent environment, viscosity changes and external pressure, and exhibits adjustable changes in emission intensity, emission wavelength and/or emission color, thus expanding the application of COF in intelligent light-emitting detection and sensing materials.
