Unusually Long-Lived Photocharges in Helical Organic Semiconductor Nanostructures

Jürgen Brugger, Andrzej Sienkiewicz, Holger Frauenrath, Valentin Flauraud, Jan Cornelius Brauer, Liangfei Tian, Thomas Schmaltz, Regina Judith Hafner

Photocharge generation and formation of long-lived charge carriers are relevant in photosynthesis, photocatalysis, photovoltaics, and organic electronics. A better understanding of the factors that determine these processes in synthetic polymer semiconduct ...

Materials Taking a Lesson from Nature

Holger Frauenrath, Emmanuel Croisier, Liangfei Tian

Structural biomaterials with their often extraordinary properties and versatile functions are typically constructed from very limited sets of building blocks and types of supramolecular interactions. In this review we discuss how, inspired by nature's desi ...

Development of a robust supramolecular method to prepare well-defined nanofibrils from conjugated molecules

Holger Frauenrath, Roman Niklaus Marty, Liangfei Tian, Ruth Szilluweit

In order to produce materials with tailored structures and functions via supramolecular self-assembly of molecular precursors in a predictable fashion, it is necessary to develop 'supramolecular methods' based on structurally simple 'supramolecular synthon ...

Multi-Set Point Intermittent Contact (MUSIC) Mode Atomic Force Microscopy of Oligothiophene Fibrils

Holger Frauenrath, Liangfei Tian, Ruth Szilluweit

We developed MUSIC-mode atomic force microscopy (AFM) to emulate intermittent contact mode AFM without a feedback loop and in the absence of lateral forces. This single-pass approach is based On maps of amplitude-phase-distance curves and allows the height ...
