“…These macromolecular systems show high resistance to combustion and unique two-dimensional structures. More recently, polypyrrole fi lms containing closoand nido-carboranes [2,14] or cobaltabisdicarbollide anions [15][16][17] were reported and were shown to have higher electrochemical stability than unsubstituted polypyrrole. Our rationale for using 3-substituted *Correspondence to: M. Graça H.

“…N,N 0 -diphenyl-N,N 0 -bis(3-methylphenyl)-1, 1 0 -diphenyl-4, 4 0 -diamine (TPD), 1,3,5-tris(N-phenylbenzimidazol-2-yl)benzene (TPBI), 4-(dicyanomethylene)-2-t-butyl-6-(1,1,7,7-tetramethyljulolidyl-9-enyl)-4H-pyran (DCJTB) were prepared by general methods and purified by train sublimation before use. Compound 5,6-Bis-[4-(naphthalene-1-yl-phenyl-amino)-phenyl]-pyrazine-2,3-dicarbonitrile (BNPPDC) was prepared similarly to the method described in the literature with slight modification [14,15].…”

“…A mixture of N-Phenyl-1-naphthylamine (2.41 g, 11 mmol), (a) (2.20 g, 5 mmol), sodium t-butoxide (1.58 g, 16.5 mmol), Pd(dba) 2 (0. 25 g, 0.44 mmol), (t-Bu) 3 P (0.13 g, 0.66 mmol), and toluene (15 ml) was heated at 80 1C for 12 h [15]. After cooling the mixture was treated with water and extracted into diethyl ether.…”

“…Considering that nucleophilicity is a problem, anions with high charge delocalization could improve the overoxidation resistance of the COPs [14]. We recently [15] have defined the practical charge density of the doping anions (ρ c ), as ρ c = q/N p , where ρ c = practical charge density, q = charge, and N p = practical number of atoms among which the charge is formally dissipated. In this sense, ρ c (Cl -) = 1/1, [20] that shields the polymer from the nucleophilic attack by OH - [21].…”
