When many of the currently largest chemical companies were founded about 150 years ago,
textile dyes constituted their first products. Interestingly, while most of the utilized colorants …

In this review, we discuss investigations of electronic excitation energy transfer in
conjugated organic materials at the bulk and single molecule level and applications of …

The molecular exciton model has received its mostextensive development and application in
the field ofmolecular crystals1• 2• More recently, numerous applications to non-crystalline …

In the last decade emerging single‐molecule fluorescence‐spectroscopy tools have been
developed and adapted to analyze individual molecules under various conditions. Single …

Abstract π‐conjugated polymers find a range of applications in electronic devices. These
materials are generally highly disordered in terms of chain length and chain conformation …

π-Stacked perylenediimides (PDIs) have strong electronic communication between the
individual molecules and show great promise as organic electronic materials for …

Conjugated polymers offer potential for many diverse applications, but we still lack a
fundamental microscopic understanding of their electronic structure. Elementary …

The blinking behavior of perylene diïmide molecules is investigated at the single‐molecule
level. We observe long‐time scale blinking of individual multi‐chromophoric complexes …

We exploit the strong excitonic coupling in a superradiant trimer molecule to distinguish
between long-lived collective dark states and photobleaching events. The population and …

We report on a novel design for the fabrication of ultrabright bowtie nanoaperture antenna
(BNA) probes to breach the intrinsic trade-off between power transmission and field …
