Preparation of Integrated Coumarin/Cyanine Systems within an Interlayer of Phyllosilicate and Fluorescence Resonance Energy Transfer
Source abstract
Abstract
Coumarin and cyanine are integrated into solid-state two-dimensional nanospace. The construction of the integrated systems is achieved by utilizing the coumarin/phyllosilicate hybrid with a covalent bond between the coumarin and phyllosilicate moieties, as a host hybrid. Fluorescence resonance energy transfer occurs from the excited coumarin moiety to cyanine.

30. The DOC molecules in the DOC/hectorite composite fluoresce when the DOC/hectorite composite is pumped at 480 nm (seeSupporting Information).

32. When the concentration of DOC increases and the molar ratio of DOC to coumarin moiety become greater than 1, the difference between the average D−A distance with and without considering the energy transfer across the two-dimensional surfaces will become significant.
33. It is also well known thatEcan be given as a function ofrfor a single pair of a donor and an acceptor:(15)E=R06/(R06+r6), whereR0is the Förster distance andris the distance between the donor and the acceptor.
34. The energy transfer can be considered to occur to both theE- andZ-isomers from the coumarin moiety because of spectral overlap (absorption and emission spectra), whereas only theE-isomer can fluoresce intensly.
