Synthesis and Characterization of Donor−Acceptor Chromophores for Unidirectional Electron Transfer

A series of electron-transfer chromophores containing a donor and acceptor linked by an alkyl spacer were synthesized, and their electronic spectra were investigated. By inclusion with amylose, the supramolecularly encapsulated chromophores exhibit enhanced fluorescence quenching with discrete dista...

description	A series of electron-transfer chromophores containing a donor and acceptor linked by an alkyl spacer were synthesized, and their electronic spectra were investigated. By inclusion with amylose, the supramolecularly encapsulated chromophores exhibit enhanced fluorescence quenching with discrete distance dependence and acquire the ability to sustain self-assemblies of a densely packed supramolecular array on a SiOH/Si substrate.
