    This book provides a guide to modern developments in photographic science and their possible applications to new and exciting areas, including nano-technology, solar cells, and organic I of this book describes the state of the art . J-aggregates are a class of molecular crystals with special known optical properties as an intense, narrow absorption peak (known as J-band) that appears at low energy where the single isolated monomer unit has almost zero absorption and the ability to give delocalized excitons. These features have been thoroughly studied in the literature and are the result of the (strong) intermolecular.

The J-aggregates of amphiphilic cyanines and unsymmetrical merocyanines are formed by the LB technique which can organize molecular films to control two-dimensional arrangements.

The ternary mixed monolayer containing a merocyanine exhibited the spectral change from the monomer and the card-liked dimmer or oligomer to the J-aggregate with an.

A J-aggregate is a type of dye with an absorption band that shifts to a longer wavelength (bathochromic shift) of increasing sharpness (higher absorption coefficient) when it aggregates under the influence of a solvent or additive or concentration as a result of supramolecular self-organisation.

The dye can be characterized further by a small Stokes shift with a narrow band. J-aggregates [18]. Dramatic transformation of PIC absorption spectrum on formation of J-aggregates is seen in figure 2.

This result illustrates that the forma-tion of J-aggregates is a dynamic and concentration-dependent process, so that in aqueous solutions even at very high dye concentrations the characteristic fea-Cited by: In our previous work on J-aggregates, the coupling strength between the monomers, which we call C, was large compared to the width, called D of the monomer absorp-tion.

In the nomenclature of Simpson and Peterson [25], C/D 1 is called the strong coupling regime. In the cases considered, this also implies that, since the shift is to lower. Get this from a library.

Soil aggregates, as noted in the section on soil structure in Chapter 1, play a central role in protecting pools of carbon and nitrogen, and are derived from a variety of sources.A mechanism particularly prevalent in many tropical soils is the physical aggregation process, which occurs abiotically as a physicochemical process (Oades and Waters, ).

J-aggregates: is bathochromic shift i.e. red-shift in absorption because of pi-pi stacking of aromatic molecules, in which molecule orient in head-to-tail fashion. The J-aggregate page is an excellent addition to Wikipedia; this page is a great start. I'd be interested to see more in the coming weeks/months on the following (either added by someone else or myself, time permitting): relevance to other systems with similar physics--e.g.

An excimer in J-aggregates has been often considered as a self-trapped exciton originating from the free exciton excited on the same aggregate and relaxed through interaction with vibronic modes.

Here we show that other types of excimers due to intermolecular off-diagonal interactions can be observed in J-aggregates of thiamonomethinecyanine dyes. These excimers arise owing to free excitons.

In book: Encyclopedia of Polymer Science and Technology (pp) The optical properties of J‐aggregates are markedly distinct from those of the individual molecules forming the aggregate.

Creating a record of accumulated knowledge in photographic science, this book also provides for these new areas a guide to the knowledge and ideas that arise from synergetic interactions between photographic science and technology which have pioneered unique applications of nano-particles, J-aggregates, and dye sensitization.A method for producing special supramolecular assemblies of colorants, in particular cyanine dyes, called J aggregates consists in depositing a monolayer of dendrimers on a support and subsequently in deposing cyanines in solution for forming the organized monolayer of J aggregates.

The method can be used for producing a secondary light source for injecting light into a waveguide from a light.H- and J-aggregates formed from a nontraditional π-gelator depending on the solvent polarity for the detection of amine vapors† Jingbo Sun, a Chong Qian, a Shenzheng Xu, a Xiaoyu Jia, a Lu Zhai, a Jinyu Zhao a and Ran Lu * a.
