J-aggregates are fascinating fluorescent nanomaterials formed by highly ordered assembly of organic dyes with the spectroscopic properties dramatically different from that of single or disorderly assembled dye molecules. They demonstrate very narrow red-shifted absorption and emission bands, strongly increased absorbance together with the decrease of radiative lifetime, highly polarized emission and other valuable features. The mechanisms of their electronic transitions are understood by formation of delocalized excitons already on the level of several coupled monomers. Cyanine dyes are unique in forming J-aggregates over the broad spectral range, from blue to near-IR. With the aim to inspire further developments, this review is focused on the optical characteristics of J-aggregates in connection with the dye structures and on their diverse already realized and emerging applications.

“…The binding modes between small molecules and DNA mainly include electrostatic attractions, major groove binding, minor groove binding, intercalation, and inter-dye interactions.C ationic molecules can be attracted to the anionic phosphodiester groups along the DNA backbone [19] although this electrostatic interaction is generally weak. Major groove binding with the double helix is rare for small molecules.…”

Two large conjugated naphthalimide derivatives with or without three-methane-bridged thiazole orange (TO3; i.e., compounds 1 a and 2 a, respectively) were designed and synthesized. The fluorescence of the naphthalimide group in compound 1 a at λ=532 nm initially decreased and that for the TO3 group at λ=655 nm increased sequentially upon adding Salmon testes (St) DNA. In contrast, without the TO3 group, the fluorescence intensity of compound 2 a monotonously decreased in response to the addition of DNA. The non-monotonic change in the fluorescence for compound 1 a could be divided into two linear sections with two different wavelengths in the range of 0

This work critically examines attempts to model the fine structure apparent in electronic spectra of cyanine dyes and their analogues. Numerous computational studies reported over the past decade attribute the origin of sub‐bands and their relative intensities to vibronic transitions in which the relevant electronic transition is coupled, irrespective of symmetry, with a collection of vibrations. It is contended that this type of approach is not supported by experimental evidence. An argument is reiterated for a more appropriate model that adheres closely to fundamental principles and fits the data. It stipulates that essentially just one symmetric vibration, carbon–carbon bond stretching of the cyanine polymethine chain, dominates the coupling and is responsible for the observed fine structure. Furthermore, it is pointed out that the intensities of the sub‐bands are readily explained by means of the Franck–Condon principle.
