Ultrafast Photoinduced Electron Transfer in Spiro-type Donor- Acceptor Systems

Perpendicular orientation of the electron donor in relation to the acceptor in the ground state seems to contribute significantly to high rate constants of the photoinduced intramolecular electron transfer (PET) in electron donor-acceptor (DA) type molecules [1]. A very interesting class of molecules in this respect are systems build around a spiro-type carbon atom, separating mutually orthogon...

A mechanically interlocked bundle.

The prototype of an artificial molecular machine consisting of a trisammonium tricationic component interlocked with a tris(crown ether) component to form a molecular bundle with averaged C(3v) symmetry has been designed and synthesized. The system is based on noncovalent interactions, which include 1) N(+)-H...O hydrogen bonds; 2) C-H...O interactions between the CH(2)NH(2) (+)CH(2) protons on...

Photoinduced Electron Transfer in Ionic Media

Title of Document: PHOTOINDUCED ELECTRON TRANSFER IN IONIC MEDIA Rebecca Cristine Vieira, Doctor of Philosophy, 2008 Directed By: Dr. Daniel E. Falvey, Department of Chemistry and Biochemistry The goal of this research was to explore the use of room temperature ionic liquids (RTILs) and ionic liquids crystals (ILCs) as reaction media for photoinduced electron transfer (PET) processes. Photoindu...

Photoinduced Electron Transfer in Langmuir-blodgett Films

Photoinduced electron transfer from an excited donor molecule (oxacyanine) to an acceptor molecule (viologen) located at the same interface in monolayer assemblies has been studied by measuring steady state fluorescence quenching and the excited state decay of the donor molecule. Donor and acceptor molecules are incorporated in matrix monolayers of arachidic acid and methyl arachidate, with a m...
