Theses, Dissertations and Culminating Projects
Two new fluorescent photoinduced electron transfer (PET) proton sensors based on anthracene and pyrazoline chromophores have been prepared. The anthracene sensor was prepared through alkylation of 2-pyridylcarbinol with 9-chloromethylanthracene and the pyrazoline sensor was prepared through an aldol condensation of 4- carboxybenzaldehyde and acetylpyridine followed by reaction with phenylhydrazine. The fluorescence of these sensors is modulated by the initiation or quenching of a PET process between the chromophore and a receptor due to protonation. The synthesis, characterization and proton binding studies of the new sensors are reported in this thesis.
