One-pot synthesis of bromo-tetracyanoazulenequinodimethanes and conducting properties of their charge transfer complexes with tetrathiotetracene

Bromo-tetracyanoazulenequinodimethanes have been synthesized by the one-pot reaction of 1,3,5-tribromoazulene with tetracyanoethylene oxide. These electron acceptors formed corresponding charge transfer complexes with tetrathiotetracene, some of which were shown to have conducting ability.
