Polyarylamine dendrimer

Hall et al. [139] produced a low-molar-mass series of polyarylamine dendrimers by using a protection/deprotection scheme involving the protected, branch cell reagent 2,4-dinitrofluorobenzene. Using various anilines as initiator cores, the... 

Hall and Polis 7 prepared a series of polyarylamines using an aromatic nucleophilic substitution-reduction sequence (Scheme 4.20). Hence, 2,4-dinitrofluorobenzene 66 was treated with />-diaminobenzene to afford tetranitro 67, which was reduced to give the corresponding first generation, diamine 68. Repetition of this sequence afforded the second generation tetradecaamine 69. These starburst polyarylamines were complexed with iodine to form semiconducting materials and were the first dendrimers to be examined by cyclic voltammetry.
