A novel polymer is developed and used as underlying interlayer to improve donor polymer/acceptor material blend morphology of active layer in polymer solar cells (PSCs). The polymer poly{N-9-[1, 17-bis-(diethylphosphonate)heptadecanyl]-2, 7-carbazole-alt-5, 5-(4, 7-di-2-thienyl-2, 1, 3-benzothiadiazole)} (PCDTBT-Pho) is designed by attaching polar phosphonate moieties to the side chain of the donor polymer, poly[N-9-heptadecanyl-2, 7-carbazole-alt-5, 5-(4, 7-di-2-thienyl-2, 1, 3-benzothiadiazole)] (PCDTBT). The pendant phosphonate moieties lead to different solubility and proper surface energy of PCDTBT-Pho. As a result, in PSC devices, the underlying PCDTBT-Pho layer facilitates the formation of biscontinuous network morphology in the active layer, makes the donor polymer enriched at the anode side, and induces the donor polymer to crystallize. These improvements contribute to improved charge separation and transport, leading to short-circuit current density enhancement by 12% and power conversion efficiency enhancement by 8% of the PSC devices. Thus, the design and application of PCDTBT-Pho indicate a novel approach to optimize active layer morphology and improve photovoltaic efficiency of PSCs.

Tailoring of phase transition temperatures of columnar liquid crystals by side chain variation is often associated with an undesired change in the mesophase type and/or geometry. To overcome this problem phenoxy-terminated side chains rather than alkyl si

The synthesis and pharmacological analyses of a number of pyrazolo[3,4-b]quinoline and benzo[b]pyrazolo[4,3-g][1,8]naphthyridine derivatives are reported. We have synthesized the diversely substituted tacrine analogues 1-6, by Friedlaender-type reaction o
Zwitterionic sulfobetaine inhibitors of squalene synthase

A substantial number of sulfobetaines (e.g., 10) have been synthesized and evaluated as inhibitors of squalene synthase (SS) on the basis of the idea that their zwitterionic structure would have properties conducive both to binding in the active site and to passage through cell membranes. When the simple sulfobetaine moiety is incorporated into compounds containing hydrophobic portions like those in farnesyl diphosphate (1) or presqualene diphosphate (2), inhibition of SS in a rat liver microsomal assay was indeed observed. For example, farnesylated sulfobetaine 10 has IC50 = 10 μM and aromatic derivative 35 has IC50 = 2 μM for SS inhibition. A wide variety of structural modifications, exemplified by compounds 43, 52, 76, 85, 91, 99, 111, and 115, was investigated. Unfortunately, no inhibitors in the submicromolar range were discovered, and exploration of a different type of zwitterion seems necessary if this appealing approach to inhibition of SS is going to provide a potential antihypercholesterolemic agent.

The mechanism of the photo-induced homolysis of aryl halides
Davidson, R.Stephen,Goodin, Jonathan W.,Kemp, Graham
, p. 2911 - 2914 (2007/10/02)
Irradiation of the ω-(4-halophenoxy)alkyl bromides (Ia,b n=10) in methanol usually leads to preferential cleavage of the aryl-halogen bond and data is presented supporting the conclusion that this occurs from the first excited single state.
