Preparation and Characterization of a π-Conjugated Donor-Accepter-type Ligand Molecule with Redox Abilities
We have synthesized a zwitterion-like molecule <B>1</B> having an <I>N</I>,<I>N</I>,<I>N</I>-tridentate ligand site for metal complexation. Compound <B>1</B> exhibited negative solvatochromism of the intramolecular charge-transfer (ICT) band in its UV–visible absorption spectrum for different polarity of solvents. Its anion radical (<B>1</B><SUP>−•</SUP>) was generated from both electrical and chemical reduction of the <I>p</I>-naphthoquinone moiety.
