- •
The emission maxima of derivatives of 2-(2′-hydroxyphenyl)imidazo[1,2-a]pyridine depends on the strength of the hydrogen bond.
- •
Improved predictions of the fluorescence characteristics can be achieved using the QTAIM approach.
- •
Easily calculated HOMA indexes based just on geometry make it possible to predict the emission wavelength of 2-(2′-hydroxyphenyl)imidazo[1,2-a]pyridine derivatives.
