Optical properties of polymethine molecules incorporated into a macroscopic set of parallel nanotubes
The structural properties of polymethine molecules incorporated into nanofibers of chrysotile asbestos have been studied by absorption-spectroscopy methods. These experiments have shown that, in chrysotile nanotubes, monomeric, all-trans- and cis-isomers, dimers and J aggregates can be observed. Upon incorporation of a dye from weakly concentrated solutions, monomeric forms of polymethine molecules, extended chromophores of which are oriented along parallel asbestos nanotubes, are predominantly observed. The hybrid material under investigation may be of interest for applied problems.
