文摘
- •
Optical response of ketocyanine dyes has been studied in cyclodextrin's nanocavity.
- •
Dyes form dimers in media where H-bonding between solvent molecules predominates.
- •
Nature of interaction of both dyes with 尾-cyclodextrin is different.
- •
Donor–acceptor–donor configured dye forms tubular suprastructure in 尾-cyclodextrin.
