Probing nanoscale domains of J-aggregates deposited on a mica surface

Article Abstract:

The quantitative analysis of the morphology of images indicates that the single domain of J-aggregates exhibits very uniform height and diameter distributions with polydispersty indices of 1.02 and 1.04 respectively. The two-dimensional nanostructure in which J-aggregates of 1,1',3,3'-tetraethyl-5,5',6,6'-tetrachlorobenzimidazolocarbocyanine (TTBC) could be arranged in a monolayer is described.

Controlled formation of the two-dimensional TTBC J-aggregates in an aqueous solution

Article Abstract:

Convincing evidence is provided on the controlled formation of the two-dimensional J-aggregates that are assembled in the herringbone morphology. The results have shown that 1,1',3,3'-tetraethyl-5,5',6,6'-tetrachlorobenzimidazolocarbocyanine (TTBC) and sodium hydroxide concentrations play a remarkable role in tuning the optical properties of TTBC aggregates.

A density functional theory study on the adsorption of chlorobenzene on the Si(111)-7 x 7 surface

Article Abstract:

The adsorption of chlorobenzene (ClPh) on the Si(111)-7 x 7 is investigated with the B3LYP density functional method. The adsorption of ClPh on the Si(111)-7 X 7 surface will first form mono-sigma binding states that are very instable.
