Photosynthetic microorganisms, such as algae, are sources of bioproducts. Because they require only sunlight, water, and carbon dioxide to grow, have potential for future mitigation CO2 emissions. However, inefficient growth these organisms remains an issue realizing emission reductions, primarily in terms photosynthetic efficiency, photoinhibition, photolimitation. Here, we show how use light ...

A perylene bisimide dye bearing amide functionalities at the imide positions derived from amino acid l-alanine and a dialkoxy-substituted benzyl amine self-assembles into tightly bound dimers by π-π-stacking and hydrogen bonding in chloroform. In less polar or unpolar solvents like toluene and methylcyclohexane, and in their mixtures, these dimers further self-assemble into extended oligomeric ...

We introduce a new family of stable high-mobility organic π-type semiconductors based on the electron-rich 10,15dihydro-5H-diindolo[3,2-a:3',2'-c]carbazole (triindole) extended π-conjugated system. This platform tends to form columnar stacks of the aromatic cores maximizing π-orbital overlap between adjacent molecules, thus paving the way for the one-dimensional migration of charge carriers alo...

Organic π-conjugated materials have been widely used for a variety of nonlinear optical (NLO) applications. Molecules with negative real components Re(γ) of the third-order polarizability, which leads to nonlinear refraction in macroscopic systems, have important benefits for several NLO applications. However, few organic systems studied to date have negative Re(γ) in the long wavelength limit,...

We measure electronic conductance through single conjugated molecules bonded to Au metal electrodes with direct Au-C covalent bonds using the scanning tunneling microscope based break-junction technique. We start with molecules terminated with trimethyltin end groups that cleave off in situ, resulting in formation of a direct covalent σ bond between the carbon backbone and the gold metal electr...

A dinuclear cobalt complex with a doubly N-confused hexaphyrin, Co2DNCH, showed high catalytic activity for electrochemical hydrogen reduction due to the wide π-conjugated system of DNCH.

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 cl...

Electroactive one-dimensional (1D) nano-objects possess inherent unidirectional charge and energy transport capabilities along with anisotropic absorption and emission of light, which are of great advantage for the development of nanometer-scale electronics and optoelectronics. In particular, molecular nanowires formed by self-assembly of π-conjugated molecules attract increasing attention for ...
