- Design, synthesis and biological activity of sphingosine kinase 2 selective inhibitors
-
Sphingosine kinase (SphK) has emerged as an attractive target for cancer therapeutics due to its role in cell survival. SphK phosphorylates sphingosine to form sphingosine 1-phosphate (S1P), which has been implicated in cancer growth and survival. SphK ex

- ORGANIC ELECTROLUMINESCENT DEVICE AND DISPLAY MEDIUM
-
An organic electroluminescent device includes: a pair of electrodes including a positive electrode and a negative electrode, at least one of the electrodes being transparent or semi-transparent; and an organic compound layer including one or more layers interposed between the pair of electrodes, at least one layer included in the organic compound layer containing one or more compounds represented by the following formula (I): in formula (I), R1s each independently representing a linear alkyl, linear alkoxy, branched alkyl, or branched alkoxy group having from 3 to 20 carbon atoms; and R2s each independently representing a hydrogen atom, a linear alkyl group having from 1 to 20 carbon atoms, a linear alkoxy group having from 1 to 20 carbon atoms, a branched alkyl group having from 3 to 20 carbon atoms, or a branched alkoxy group having from 3 to 20 carbon atoms.

A thiazolothiazole derivative is represented by the following Formula (I). In Formula (I), each R1 independently represents a straight chain alkyl group having 3 to 20 carbon atoms, a straight chain alkoxy group having 3 to 20 carbon atoms, a branched alkyl group having 3 to 20 carbon atoms, or a branched alkoxy group having 3 to 20 carbon atoms; and each R2 independently represents a hydrogen atom, a straight chain alkyl group having 1 to 20 carbon atoms, a straight chain alkoxy group having 1 to 20 carbon atoms, a branched alkyl group having 3 to 20 carbon atoms, or a branched alkoxy group having 3 to 20 carbon atoms.

- A deeper insight into the dithiocarbamate precursor route: Synthesis of soluble poly(thienylene vinylene) derivatives for photovoltaic applications
-
The synthesis of, two new poly(thienylene vinylene) derivatives is described, i.e. poly(3-octyl-2,5-thienylene vinylene) (O-PTV) and poly(bis[octylphenyl-2,5-thienylene vinylene]) (BOP-PTV). Both polymers have been prepared via the dithiocarbamate (DTC) precursor route. The polymerization protocol of the monomer toward the precursor polymer has been optimized by the use of different bases, leading to improved reproducibility of the polymerization step. Processability has been guaranteed by the introduction of alkyl side chains. Finally the precursor polymers were converted toward conjugated polymers and they were fully characterized by UV/vis, IR, GPC, and cyclic voltammetry. Bulk heterojunction solar cells with PCBM as acceptor showed promising power conversion efficiencies of 0.80% for BOP-PTV and 0.92% for O-PTV.

- Self-assembled fluorescent hexaazatriphenylenes that act as a light-harvesting antenna
-
In this paper we report the self-assembling nature of fluorescent hexaazatriphenylenes (HATs) 6a-d with six alkyl/alkoxy-chain-containing biphenyl groups and their application to light-harvesting antennae. In a nonpolar solvent and the film state, the HAT
