Through a cycloaddition reaction, fullerene (C60) was derivatized with a novel organic compound 5-(benzo[b]thiophen-3-yl)pyridine-3-carbaldehyde to form the processable and stable 3-(benzo[b]thiophene-3yl)-5-fullero-1-methylpyrrolidinepyridine (BTFP) compound. BTFP exhibits close similarities to phenyl-C61-butyric-acid-methyl-ester (PCBM) in terms of first reduction potential values (-0.62 and ...

Delavirdine mesylate (U-90152T) is a highly specific nonnucleoside reverse transcriptase inhibitor currently under development for the treatment of AIDS. The excretion, disposition, and metabolism of delavirdine were investigated in Sprague-Dawley rats after oral administration of [14C]delavirdine mesylate at single doses ranging from 10 to 250 mg/kg and multiple doses ranging from 20 to 250 mg...

A water-soluble covalently linked C(60)-porphyrin compound-C(60)Por is reported to show enhanced DNA-cleaving activity. The highly enhanced DNA-cleaving activity is expected to be ascribed to the high water-solubility and affinity of C(60)Por to DNA, as well as to the accessibility to the charge-separated states C(60)˙(-)-Por˙(+) formed under radiation.

We investigated the role of a functional solid additive, 2,3-dihydroxypyridine (DHP), in influencing the optoelectronic, morphological, structural and photovoltaic properties of bulk-heterojunction-based polymer solar cells (BHJ PSCs) fabricated using poly(3-hexylthiophene): indene-C60 bisadduct (P3HT:IC60BA) photoactive medium. A dramatic increase in the power conversion efficiency (~20%) was ...

The review focuses current research in the rapidly developing chemistry of porphyrin-fullerene complexes, and highlights recent advances in the synthesis, properties, and potential applications of this family. An overview of the most popular methods to prepare porphyrin complexes with C60 fullerene exhibiting various types of linkage is given with the main focus on the Prato reaction and its mo...

Chitosan-grafted-poly(4-vinylpyridine) (Cs-PVP) copolymers could be synthesized under heterogeneous conditions in presence of a potassium persulfate and sodium sulfite redox system. The synthesized graft copolymer could be utilized effectively, in the form of beads, as an efficient catalyst for Michael additions of active methylenes to functionally substituted alkenes. Moreover, methyl moiety o...

6-Azafulleroid-6-deoxy-2,3-di-O-myristoylcellulose (3) was synthesized from 6-azido-6-deoxycellulose (1) by two reaction steps. The myristoylation of compound 1 with myristoyl chloride/pyridine proceeded smoothly to give 6-azido-6-deoxy-2,3-di-O-myristoylcellulose (2) in 97.0% yield. The reaction of compound 2 with fullerene (C(60)) was carried out by microwave heating to afford compound 3 in h...

Quantitative analyses of individual bile acids in biological samples are limited by the lengthy multistep preparations necessary. Using heptafluorobutyric acid anhydride in pyridine as derivatizing agent, we reduced several steps to one. Bile acids and their glycine and taurine conjugates form stable heptafluorobutyrate derivatives, climinating the need for deconjugation and preparation of meth...

A new, highly flexible porphyrin dimer was isolated in preparative scale from a dynamic disulfide library; this receptor adjusts to fit guests with a wide range of steric requirements and, whilst C60 proved to be an unsuitable template for this library, a new C60-porphyrin complex was isolated and characterised.
