2-Diformylmethylene-1,3-diselenole was prepared and condensed with dithiolium phoshoniumbromides and dithiolium phosphonates in the presence of base to give dendralene-type vinylogs ofTTF bearing a 1,3-diselenole moiety. The electrochemistry of these dendrimers was studied. SEEPRmeasurements were also carried out. Calculations were carried out on the radical cations andcorrelated with the EPR values.
