Zhang, Yan;Li, Yuhao;Su, Chengyong;Barboiu, Mihail research published 《 Dynameric Frameworks with Aggregation-Induced Emission for Selective Detection of Adenosine Triphosphate》, the research content is summarized as follows. Luminogenic materials with aggregation-induced emission (AIE) have attracted considerable interest for applications. If these systems aggregate, the free rotation of their scaffold is restricted, and as a consequence the photoluminescence increases. Herein, the first exptl. observation of a “dynameric effect” on AIE is described. A comparison is made of the AIE of mol. and dynameric sensors that exhibit non-linear turn-on switching of fluorescence upon their interaction with ATP (ATP). Confirmation was obtained from the enhanced ATP detection with multivalent dynameric networks compared with a mol. sensor. The dynamic, reversible behavior of the imine linkages is critical to produce this enhancement, as a static, imine-reduced, polymeric sensor showed decreased AIE activity. The dynameric frameworks showed selectivity for ATP over ADP, and adenosine monophosphate over guanosine triphosphate or cytidine triphosphate. Together, these results will accelerate the systematic discovery of efficient adaptive biomimetic sensors.
