Two strong quadruple hydrogen-bonded units (ureidopyrimidine and pyrimidinedione) have been used to assemble Newkome-type dendrimers and ferrocene, respectively, in this work. Generation-dependent dimerization was observed in the dendrimers' case, and strong electronic communciation was found between the two ferrocene centers via hydrogen bonding. Solvents also play a role in the ability of dimerization through ureidopyriminidine units. Evidence from electrochemical data confirmed that the electronic communication happened between two ferrocene centers in the dimers.
