Electronic Spectra and Electronic Structures of Aminoanthracenes

Electronic Spectra and Electronic Structures of Some Antimicrobials Derived from Proflavine

“…The second longest wavelength band of an arylamine originates from an essentially ring-localized transition and is relatively unaffected by protonation of the amino group (8). The second longest wavelength band of an arylamine originates from an essentially ring-localized transition and is relatively unaffected by protonation of the amino group (8).…”

“…The longest wavelength absorption bands of arylamines may be thought to originate from the transfer of electronic charge from the amino group to the vacant r*-orbitals of the aromatic ring as a result of the interaction of the ground-state molecular electronic distribution with the electric vector of the exciting light (8). In the ground state, the aromatic ring is weakly conjugated with the amino group; but in the excited state the amino group is more extensively conjugated with the aromatic ring, resulting in stabilization of the excited state relative to the ground state.…”

Binding of N-Substituted Anthracenecarboxamides to Double-Stranded DNA: An Electronic Spectral Study

“…As a result, the lLa band loses vibrational structure and moves to longer wavelengths relative to its position in anthracene while the 'Lb band retains structure and is only slightly affected (11)(12)(13). As a result, the lLa band loses vibrational structure and moves to longer wavelengths relative to its position in anthracene while the 'Lb band retains structure and is only slightly affected (11)(12)(13).…”

Maintaining of the Green Fluorescence Emission of 9-Aminoanthracene for Bioimaging Applications

“…10,11 Polymers constructed with 1-amino and 9AA units are also found to emit green fluorescence similar to their monomers, 12 whose absorption spectra have been compared to those of 2-aminoanthracenes. 13,14…”
