초록
Photo-/electroactive donor-acceptor (D-A) chromophores were synthesized and investigated for energy- and electron-transfer (ET/eT) properties, for which the chromophores are supramolecularly integrated by encapsulation with helical amylose, rendering the chromophores aggregation-free and rigidified along the helical axis and thus, a remarkably enhanced fluorescence intensity. Fluorescence quenching studies indicated that the helical encapsulation gives the ET/eT a clear D-A distance dependence unlike with the encapsulation-free counterparts, being reflected in their florescence decay profile. Another notable difference is that the helical supramolecule of the chromophores forms a perpendicularly oriented self-assembly. Transport behavior in the solid state will be also discussed.
