Outline of Final Research Achievements

A novel fluorescence (FL) sensory system orchestrated by self-assembly was offered: namely, the difference in the guest structural information at a molecular level directs distinct self-assembly modes (J-type or H-type) of newly developed FL chemosensors and consequently leads to the FL outputs characteristic of the initial guest information. This macroscopic expression of the initial microscopic difference in the guest structures exemplifies the emergent property of self-assembly for the application to the FL sensing, which is distinguishable from the conventional one based on molecular recognition through lock-and-key-type 1:1 binding. This study does emphasize that precise translation of guest structural information into FL output can be realized through the emergent property of self-assembly, and accordingly highlights self-assembly as a sensory system for molecular recognition.
