“Click-fluors”: Modular Fluorescent Saccharide Sensors Based on a 1,2,3-Triazole Ring

A carbohydrate sensing “click-fluor” is reported which
displays a nontypical binding preference with sample saccharides. That a fluorescent sensor is generated as a result
of triazole formation (click reaction), rather than simply
bringing the sensor and reporter units together via a triazole
linkage, and the potential applicability of the wide range of
easily accessible acetylene units means a simple strategy for
the development of modular fluorescent sensor arrays for
rapid screening of target saccharides will be available.
