Donor-Acceptor Block Copolymers for Charge Separation at Nanostructured Interfaces
… was used as hole conductor in combination with perylene bisimide as dye and electron conductor. First, a soluble perylene bisimide monomer had to be synthesized. This was achieved by an unsymmetrical synthesis starting from the perylene-3,4:9,10-tetracarboxylic bisanhydride. For the solubility a …

A Showcase of Functional Fluorous Materials and Their Applications
… photophysical properties of “fluorofluorescent” perylene bisimides, where fluoro- refers to both fluorine and fluorescence. These perylene bisimides were utilized to realize the concept of a fluorofluorescent solar concentrator. In Chapter 3, we report the synthesis and photophysical properties …

Luminescent organic materials and their application in solar technologies
… surrogate absorbers for a minority amount of the perylene bisimide Lumogen F Red 305. We developed a small LSC wherein a mixture of the two polymers act as both the host layer and antennae for a 1.5 wt% loading of Lumogen F Red 305. A Monte Carlo simulation predicts the LSC to possess high edge …

Electrical characterization of large-area donor-acceptor molecular junctions
… four Langmuir-Blodgett films studied, three had perylene bisimide as the common acceptor with the donors, pyrene, ferrocene, and tetramethyl-p-phenylenediamine. The fourth Langmuir-Blodgett film is an iron complex. The large extinction coefficient of the three perylene monolayer films make them …
