Effect of potassium intercalation on the electronic and vibrational properties of benzylic amide [2]catenane films

The appearance of gap states in benzylic amide catenane thin films following potassium intercalation was investigated by electron energy loss spectroscopy and quantum chemical calculations. Both theory and experience find an excitation energy for transitions into these new states of ∼2 eV. The chara...

Description
Summary:The appearance of gap states in benzylic amide catenane thin films following potassium intercalation was investigated by electron energy loss spectroscopy and quantum chemical calculations. Both theory and experience find an excitation energy for transitions into these new states of ∼2 eV. The characteristics of these states are discussed.
