Abstract
Energies of the first charge-transfer bands of complexes of heterocyclic pyridinium-like cations with various electron donors (the iodide ion, benzenoid hydrocarbons) yield linear correlations with the HMO energies of the lowest unoccupied π-molecular orbitals (LUMO) of the heterocyclic acceptors. The experimental chargetransfer band maxima were taken from the literature. Charge-transfer band maxima for the complexes of the 2,4,6-trimethylpyrylium cation with several electrons donors (diethylamine, N,N-dimethylaniline, pyridine N–oxide, anthracene) have been determined and compared with the analogous data for the tropylium cation.
