We have synthesized a zwitterion-like molecule 1 having an N,N,N-tridentate ligand site for metal complexation. Compound 1 exhibited negative solvatochromism of the intramolecular charge-transfer (ICT) band in its UV–visible absorption spectrum for different polarity of solvents. Its anion radical (1−•) was generated from both electrical and chemical reduction of the p-naphthoquinone moiety.

We have synthesized a donor-type ligand 1a–1f containing a 1,3-dithiol ring as the donor site and an N,N,N-tridentate ligand for metal complexation. In the crystal phase, the planar 1a molecules stack along the b axis in the “head-to-tail” fashion. The FeII complex 2 shows typical paramagnetic behavior.

Fused donor-acceptor triads composed of two tetrathiafulvalenes (TTFs) and benzoquinone (BQ; 1) or naphthoquinone (NQ; 2) were successfully synthesized. X-ray structure analysis of the bis(n-butylthio) derivative revealed that the molecules are stacked in a head-to-tail manner. The bis(n-hexylthio)-1 exhibited six-pairs of one-electron transfer waves in the cyclic voltammogram, corresponding to the
