Molecular Tubes for Lipid Sensing: Tube Conformations Control Analyte Selectivity and Fluorescent Response
摘要:
Two fluorescent sensors for lipids have been prepared and tested for detection of a number of hydrophobic compounds of varying shape and size. The data suggest that the two sensors have a different mode of fluorescent response. Yet, the two sensors are only different in the bridging group one having a flexible amide and one having a rigid allyl bridge. The fluorescence data are explained based on a difference in conformation of the two sensors in aqueous solution.
isomers of the naphthotubes with four carboxylate groups were found to be assigned incorrectly in our earlier publication. Further evidence is provided here for the new assignment. The implications of this new structural assignment for the conclusions drawn in the earlier works are discussed as well.
