In this report, a vastly improved method for the synthesis of [2.2.3]-triazacryptand (TAC), an excellent K+-selective cryptand, is disclosed, which provides a shorter synthetic route with > fivefold higher overall yield. On the basis of the improved synthesis, a TAC-BODIPY conjugate was developed for K+ sensing. TAC-BODIPY is a fluorescence turn-on K+ sensor exhibiting high selectivity toward K+ over other biologically relevant metal cations. Cell imaging studies are presented and demonstrate that TAC-BODIPY is suitable for dynamic K+ sensing in live cells.
