Heterocyclic structures applied as efficient molecular probes for the investigation of chemically important interactions in the liquid phase

 Heterocyclic molecular probes were applied for the investigation chemically significant effects of the liquid phase to solute materials. A brief historic overview of the estimation of solvent effects is reported as well as most recent developments. The familiar three-dimensional concepts of solvent–solute interactions were upgraded to two-dimensional effects similar to surfaces where heterocyclic structures with compensating dipoles give basic insights in processes on the molecular level.
