isolated by decomposition of the productcomplex. The incorporation of two oxygen atoms from H(2)O(2) into the ligand was confirmed by isotope labeling studies using H(2)(18)O(2). The pathway of the unusual double hydroxylation was investigated by preparing the two isomeric phenolic derivatives of L, namely 3,5-bis([bis[2-(1-methyl-1H-benzimidazol-2-yl)ethyl]amino]methyl)phenol (6) and 2,6-bis([bis[2-(1-
Novel triazole dendritic molecules bearing dimethyl isophthalate surface group are synthesized. The enhancement of triazole and carboxylate groups in the dendritic structures significantly alter the absorption, electrochemical and DSSCs behaviors. With dendritic additive DSSCs cell exhibited higher Voc values and power conversion efficiency (η) in I−/I3−redox couple under simulated AM 1.5 at 40 mW cm−2.

Fréchet-type dendrimers with hole-transporting diphenylamine as surface group and electron-transporting triazole moiety as building block have been synthesized by convergent synthetic strategy through ‘click chemistry’ methodology. First generation dendrimer exhibits longer relaxation time, higher quantum yield in the fluorescence spectrum, and better thermal stability than the zero and second generation
