Abstract:In blended hybrid systems distinct micro-or nanostructured materials can be formed by phase separation. Network structures of particles or rods in a polymer matrix can be developed via self-assembly. We use this blending approach to compare active materials for application in solar cell devices. Blends were fabricated from either poly(hexylthiophene) P3HT or poly(triphenylamine) PTPA mixed with nanocrystalline TiO 2 rods. In this manner, we compare two different hole conducting polymers in their performance in photovoltaic devices, while experimental conditions are kept identical. We find that the choice of solvent and photovoltaic characterization conducted in inert atmosphere is of importance for blends prepared from P3HT/TiO 2 blends, but not for PTPA/TiO 2 blends. Even though prepared with the same TiO 2 rods, solar cells prepared from PTPA blends showed an enhanced efficiency when measured under ambient conditions. Furthermore, the PTPA/TiO 2 showed higher long-term stability. OPEN ACCESSEnergies 2010, 3 302

“…The final example concerns polymeric photovoltaics (for recent reviews, see [431][432][433][434][435]) where block copolymeric self-assembly turns out to be interesting due to the enhanced amount of available interfaces [436][437][438][439][440][441][442][443][444][445].…”

“…Polymerization via reversible addition-fragmentation chain transfer (RAFT) can be only readily mediated using xanthates or dithiocarbamate as the chains transfer agent [16,[18][19][20][21] or nitroxide-mediated polymerization (NMP) [22] and by atom transfer radical polymerization (ATRP) [23,24]. Several attempts for synthesis of vinyl polymers having triphenylamine as pendant groups, using controlled radical polymerization (NMP [25][26][27][28] and RAFT [29][30][31][32]) or living anionic route [33][34][35][36][37][38][39][40] have been recently reported. However, the controlled radical polymerization of triphenylamine-based (meth) acrylate monomers was less studied until now, only a paper revealing the group transfer polymerization of 4-(dimethylamino)benzyl methacrylate was published [41].…”

Abstract. benzyl methacrylate] with well-defined molecular weight and low polydispersity was prepared by atom transfer radical polymerization (ATRP) using 4-(diphenylamino) benzyl 2-bromo-2-methyl-propanoate as initiator and CuBr/2,2!-bipyridine as catalytic complex. Electrochemical behavior and optical properties of the polymers were investigated by cyclic voltammetry and UV-Vis and fluorescence spectroscopy. Cyclic votammetric studies revealed that the redox processes were accompanied by dimerization of triphenylamine pendant groups. The initial polymer was postmodified, in solution or bulk, by electrochemical oxidation leading to a crosslinked and insoluble network with electrochromic properties, accompanied by strong color changes with high coloration efficiency. The crosslinking reaction took place between triphenylamine groups through para free positions leading to tetraphenylbenzidine bridges. The structure of polymers was confirmed by Fourier transform infrared (FT-IR) spectroscopy and 1 H and 13 C-nuclear magnetic resonance spectroscopy. Morphology studies of the cross-linked film have evidenced a smooth and continuous aspect without any pinholes or defects.
