Abstract:The current work focuses on the investigation of two functionalized naphthyridine derivatives, namely ODIN‐EtPh and ODIN‐But, to gain insights into the hydrogen bond‐assisted H‐aggregate formation and its impact on the optical properties of ODIN molecules. By employing a combination of X‐ray and electron crystallography, Absorption and Emission spectroscopy, time resolved fluorescence and ultrafast pump‐probe spectroscopy (visible and infrared) we unravel the correlation between the structure and light‐matter … Show more
A hierarchical model describes the evolution of chiroptical spectra of C8O3 cyanines from solvated to interacting dyes in tubular aggregates, and finally in bundles. The aggregation of aggregates implies strongly amplified chiroptical responses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
