Abstract
The absorption bands characteristic of the solid molecular complexes of tetracyanoethylene are attributed to the charge transfer interaction between tetracyanoethylene and donor molecules. In the complexes with polycyclic aromatic hydrocarbons the energy gap associated with the semiconductivity agrees well with the energy of the charge transfer excitation in the crystalline state, while the former is much smaller than the later in the complexes with polymethylbenzenes and azulene.Keywords
