The ability to control photoinduced charge transfer within molecules represents a major challenge requiring precise control of the relative positioning and orientation of donor and acceptor groups. Here we show that such photoinduced charge transfer... Read More about Selective photoinduced charge separation in perylenediimide-pillar[5]arene rotaxanes.

Synthesis and characterisation of rylene diimide dimers using molecular handcuffs (2019)
Journal Article
Yang, L., Langer, P., Davies, E. S., Baldoni, M., Wickham, K., Besley, N. A., Besley, E., & Champness, N. R. (2019). Synthesis and characterisation of rylene diimide dimers using molecular handcuffs. Chemical Science, 10(13), 3723-3732. https://doi.org/10.1039/c9sc00167k

A strategy for positioning, and loosely connecting, molecules in close proximity using mechanically interlocked handcuffs is described. The strategy is demonstrated using rylene diimides, creating dimeric structures in which two components are linked...

Perylene diimides (PDIs) are promising candidates for n-type semiconductor materials and, thus, for use in organic electronics. Thionation of the imide moiety provides an efficient strategy to control the donor−acceptor gap of these types of compounds...

The application of metal-organic framework (MOF) materials in electrochemical and electrochromic devices remain rare. One of the main reasons for this is the inability to readily access their detailed electrochemistry. The inherent insolubility of th...
