Liquid crystals bearing extended ?-conjugated units function as organic semiconductors and liquid crystalline have been studied for their applications in light-emitting diodes, field-effect transistors, solar cells. However, studies on electronic functionalities chiral crystal phases limited so far. Electronic charge carrier transport has confirmed nematic smectic C phases. In the phase, consis...

Ultrasmall gold nanoparticles with a metallic core diameter of 2 nm were surface-conjugated peptides that selectively target epitopes on the surface WW domain model protein hPin1 (hPin1-WW). The binding to was accomplished via thiol group terminal cysteine. particles analyzed by NMR spectroscopy, high-resolution transmission electron microscopy, and differential centrifugal sedimentation. loadi...

BACKGROUND Staphylococcal protein A (SPA) is a cell wall component of Staphylococcus aureus that binds to different IgG subclasses of human and several animal species. This bacterial protein can be used as an antibody detector in various immunological assays or as an isolation reagent for the purification of antibody molecules via immuno-chromatography procedures. OBJECTIVES Molecular cloning...

Intermolecular interactions of the cyclic conjugated molecule (DBA) with hydrogen, nitrogen and carbon dioxide molecules were evaluated by high level ab initio calculations.

We show that adding chlorine atoms to conjugated cores is a general, effective route toward the design of n-type air-stable organic semiconductors. We find this to be true for acenes, phthalocyanines, and perylene tetracarboxylic diimide (PDI)-based molecules. This general finding opens new avenues in the design and synthesis of organic semiconductors. We compared a series of fluoro- and chloro...

Pyrrole-based π-conjugated anion-responsive molecules bearing an anionic moiety form self-complementary dimers, which exhibit self-sorting behaviours depending on the substituted positions of anionic sites.

Non-chiral metal nanoparticles conjugated with chiral oligonucleotide molecules demonstrated a circular dichroism (CD) at the plasmonic wavelengths due to aggregation effects.

Most dicyclopenta-fused polyacenes are predicted to be moderately aromatic and diatropic, although they have no (4n + 2)-site conjugated circuits. We applied our graph theory of aromaticity and magnetotropicity to these molecules and found that these anomalous properties arise from a set of non-conjugated circuits, which contribute collectively to aromaticity and diatropicity. This result indic...

Using a perturbative approach to simple model systems, we derive useful propensity rules for inelastic electron tunneling spectroscopy (IETS) of molecular wire junctions. We examine the circumstances under which this spectroscopy (that has no rigorous selection rules) obeys well defined propensity rules based on the molecular symmetry and on the topology of the molecule in the junction. Focusin...
