Solvent and substituent effect on electronic spectra of N-(4-substitutedphenyl)-2,3-diphenylpropanamides
Апстракт
The UV absorption spectra (200-400 nm) of eleven N-(4-substituted phenyl)-2,3-diphenyl-propanamides 1 have been recorded in fourteen solvents of different polarity. A simple Hammett equation was used to study the effects of substituents on the UV spectra of compounds 1. The effects of solvent polarity and hydrogen bonding on the absorption spectra are interpreted by means of linear solvation energy relationships. The results show that the solvent effect on UV absorption spectra of the investigated amides are very complex and strongly depends on the nature of the substituents of the phenyl ring.
