Au@SiO2 nanoparticles coupling co-sensitizers for synergic efficiency enhancement of dye sensitized solar cells

21-11-2012 | Haoran Li; Wei Hong; Feiyang Cai; Qi Tang; Yang Yan; Xiaobin Hu; Binyuan Zhao; Di Zhang; Zhou Xu, Journal of Materials Chemistry, 2012

A new configuration of a co-sensitized DSSC was proposed, in which different dye molecules are deposited onto the electrodes layer-by-layer, with Au@SiO2 nanoparticles uniformly distributed in the electrodes. Au@SiO2 nanoparticles coupled with dye pairs were proven to have a synergic effect: not ...

Near-infrared photoluminescence from molecular crystals containing tellurium

21-11-2012 | Hong-Tao Sun; Yoshio Sakka; Naoto Shirahata; Minoru Fujii; Tetsu Yonezawa, Journal of Materials Chemistry, 2012

We report the observation of near-infrared photoluminescence from Te4(Ga2Cl7)2 and Te4(Al2Cl7)2 molecular crystals containing Te42+ polycations. The experimental and theoretical results clearly revealed that the Te42+ polycation is a smart near-infrared emitter with characteristic emission peaks ...

Pyrene-directed growth of nanoporous benzimidazole-linked nanofibers and their application to selective CO2 capture and separation

15-11-2012 | Mohammad Gulam Rabbani; Ali Kemal Sekizkardes; Oussama M. El-Kadri; Bilal R. Kaafarani; Hani M. El-Kaderi, Journal of Materials Chemistry, 2012

A pyrene-based benzimidazole-linked polymer (BILP-10) has been synthesized by the co-condensation of 1,3,6,8-tetrakis(4-formylphenyl)pyrene and 1,2,4,5-benzenetetramine tetrahydrochloride in dimethylformamide. The use of pyrene as a molecular building unit leads to the formation of self-assembled ...

Lipophilic and cationic triphenylphosphonium grafted linear polyethylenimine polymers for efficient gene delivery to mammalian cells

15-11-2012 | R. Bansal; S. K. Tripathi; K. C. Gupta; P. Kumar, Journal of Materials Chemistry, 2012

Synthetic chemical vectors have recently provided a versatile and robust platform for the safe and efficient delivery of exogenous genes. Here, for the first time, a small series of N-butyltriphenylphosphonium bromide-grafted-linear polyethylenimine (BTP-g-lP) polymers (N–P hybrid polymers) have ...

Charge separation dynamics in a narrow band gap polymer–PbS nanocrystal blend for efficient hybrid solar cells

15-11-2012 | Claudia Piliego; Marianna Manca; Renee Kroon; Maksym Yarema; Krisztina Szendrei; Mats R. Andersson; Wolfgang Heiss; ..., Journal of Materials Chemistry, 2012

We have demonstrated efficient hybrid solar cells based on lead sulfide (PbS) nanocrystals and a narrow band gap polymer, poly[{2,5-bis(2-hexyldecyl)-2,3,5,6-tetrahydro-3,6-dioxopyrrolo[3,4-c]pyrrole-1,4-diyl}-alt-{[2,2′-(1,4-phenylene)bis-thiophene]-5,5′-diyl}], (PDPPTPT). An opportune mixing of ...

Synthesis of high-charge capacity triarylamine–thiophene redox electrodes using electrochemical copolymerization

15-11-2012 | Jeremy T. Kearns; Mark E. Roberts, Journal of Materials Chemistry, 2012

Growing interest in electric transportation and renewable energy generation places a high burden on the development of new materials and devices capable of storing and delivering energy at high rates. We have previously shown that efficient, reversible redox couples can be incorporated in ...

Vacuum thermally evaporated polymeric zinc acrylate as an organic interlayer of organic/inorganic multilayer passivation for flexible organic thin-film transistors

07-11-2012 | Won Min Yun; Jaeyoung Jang; Sooji Nam; Yong Jin Jeong; Lae Ho Kim; Seyeol Park; Sang Joon Seo; Chan Eon Park, Journal of Materials Chemistry, 2012

Polymeric zinc acrylate (pZA) was introduced as an organic interlayer for the inorganic/organic multilayer passivation of flexible organic thin film transistors (OTFTs). The pZA film was deposited by thermally evaporating a zinc diacrylate (ZDA) monomer under high vacuum ...

Low-cost materials for boron adsorption from water

06-11-2012 | Cristina Sanfeliu; Ramón Martínez-Máñez; Félix Sancenón; Juan Soto; Victoria Puchol; Pedro Amorós; M. Dolores Marcos, Journal of Materials Chemistry, 2012

Knowing the affinity of boron aqueous species for cis-diol organic groups, five different hybrid materials have been prepared by anchoring glucose groups onto the surface of silica matrices with a different surface topology: UVM-7 bimodal mesoporous silica, UVM-11 unimodal non-templated ...
