Origin of aromatic character in porphyrinoid systems

Timothy D. Lash2011-11-01Journal of Porphyrins and Phthalocyanines

The aromatic nature of porphyrins is commonly attributed to the presence of an [18]annulene substructure. However, this viewpoint has been disputed. Drawing on a range of examples of carbaporphyrinoid systems from the author's own studies, the [18]annulene model is shown to be a self-consistent and insightful approach…

Antibonding Plasmon Modes in Colloidal Gold Nanorod Clusters

Marek Grzelczak、Stefano A. Mezzasalma、Weihai Ni 等 10 位作者2011-11-01Langmuir

The optical response of nanoplasmonic colloids in disperse phase is strictly related to their shape. However, upon self-assembly, new optical features, for example, bonding or antibonding modes, emerge as a result of the mutual orientations of nanoparticles. The geometry of the final assemblies often determines which…

Uniaxial to biaxial nematic phase transition in a bent-core thermotropic liquid crystal by polarising microscopy

Stephen J. Picken、Theo J. Dingemans、Louis A. Madsen 等 5 位作者2011-11-01Liquid Crystals

Polarising optical microscopy (POM) shows evidence for a reversible uniaxial nematic (NU) to biaxial nematic (NB) phase transition in a quiescent melt of bent-core mesogens (BCM). A second superimposed Schlieren texture, attributed to a second director field, grows into the NU phase on lowering the temperature and dis…

Effect of ball milling and post treatment on crystal defects and transport properties of Bi2(Se,Te)3 compounds

Sin-Shien Lin、Chien‐Neng Liao2011-11-01Journal of Applied Physics

Ionized point defects that act as electron donors or acceptors can strongly affect thermoelectric transport properties of bismuth telluride compounds. These crystal imperfections including antisite defects and vacancies can be generated or annihilated during material processing. Here, we reported the effect of ball mi…

Development and evaluation of pH-responsive single-walled carbon nanotube-doxorubicin complexes in cancer cells

Jinping Cheng、Gu、Jin 等 5 位作者2011-11-01International Journal of Nanomedicine

Single-walled carbon nanotubes (SWNTs) have been identified as an efficient drug carrier. Here a controlled drug-delivery system based on SWNTs coated with doxorubicin (DOX) through hydrazone bonds was developed, because the hydrazone bond is more sensitive to tumor microenvironments than other covalent linkers. The S…
