Conclusions
-
1.
The absorption spectra of triplet exciplexes with localized excitation contain charge transfer bands, but these bands are not found for triplet exciplexes with complete charge transfer. This behavior is a consequence of the significant differences in the equilibrium conformations of such exciplexes.
-
2.
The absorption spectra of polar triplet exciplexes of quinones with secondary aromatic amines feature a hypsochromic shift of the absorption band of the radical-anion part due to strong hydrogen bonding between the radical-ions within the exciplex.
