«Acridine – a Promising Fluorescence Probe of Non-Covalent Molecular Interactions»
Zeitschrift für Physikalische Chemie, 2013, accepted
Abstract
Fluorescence and absorption spectral parameters of acridine
have been studied in solution at room temperature in the presence of
different proton donors aiming to inspect whether or not acridine can be
used as a spectroscopic probe suitable to measure the geometry of hydrogen
bonds under different conditions. It has been shown that the
most appropriate spectral parameter is the position of fluorescence maximum
that changes heavily upon a contraction of the N…H distance.
Presumably, also the intensity of the maximum strongly depends on the
hydrogen bond geometry. These two parameters can be used to establish
two independent, mutually complementary correlations connecting
the spectral manifestations and the geometry of hydrogen bond.
