Structural and Photophysical Templating of Conjugated Polyelectrolytes with Single-Stranded DNA

Ursula Röthlisberger, Polydefkis Diamantis, Natalie Renuka Banerji

A promising approach to influence and control the photophysical properties of conjugated polymers is directing their molecular conformation by templating. We explore here the templating effect of single-stranded DNA oligomers (ssDNAs) on cationic polythiop ...

Topology-Driven Single-Molecule Conductance of Carbon Nanothreads

Anne-Clémence Corminboeuf, Ganna Gryn'ova

Highly conductive single-molecule junctions typically involve pi-conjugated molecular bridges, whose frontier molecular orbital energy levels can be fine-tuned to best match the Fermi level of the leads. Fully saturated wires, e.g., alkanes, are typically ...
