M. Abe et al., A FLUORESCENT HOST - DIRECT MONITORING OF MULTIPLE HYDROGEN-BONDING INTERACTION BY THE SPECIFIC FLUORESCENCE OF THE AROMATIC AMIDE UNIT, Chemistry Letters, (9), 1993, pp. 1541-1544
The host 1 having aromatic amide structure exhibits an anomalous fluor
escence with a large Stokes shift at around 500 nm, and multiple hydro
gen-bonding interaction of the host 1 with uracil derivatives is direc
tly monitored by increase of this fluorescence intensity when the amid
e bond rotation is affected by the association.
