Systematic Modifications of a Simple Tolan: Another Category of Viscosity Sensor
摘要:
The first tolan derivative-based viscosity sensor (5d) has been synthesized, and its fluorescence intensity and lifetime increase when the viscosity of the solvent increases in methanol glycerol mixtures. Phthalide (5d) was selected among structurally diverse tolan derivatives through systematic modifications of a simple tolan. To test 5d as a viscosity sensor, fluorescence lifetime imaging (FLIM) images of HeLa cells were obtained upon treatment with 5 irM of 5d to map the viscosity of the HeLa cells.

compounds were investigated. Significant differences in the quantum efficiency and radiativedecay constant for the ICT-based emission of the two compounds verified that the structuralgeometryaround the o-carborane unit was a decisive factor in controlling the efficiency of the ICT-based radiativedecay in o-carboranyl luminophores.
