Excitonic channels from bio-inspired templated supramolecular assembly of J-aggregate nanowirest

Frank Nüesch, Jakob Heier, Surendra Babu Anantharaman

Supramolecular assemblies with controlled morphology are of paramount importance for energy transport in organic semiconductors. Despite considerable freedom in molecular design, the preparation of dyes that form one dimensional J-aggregates is challenging ...

Physical vapour deposition of cyanine salts and their first application in organic electronic devices

Frank Nüesch, Jakob Heier, Antonia Neels, Léo Duchêne, Donatas Gesevicius

A symmetrical trimethine indocyanine dye chromophore was modified with the bistriflylimide anion to study the changes in Coulomb interactions, thermal stability and the volatility of the organic salt. The bulky bistriflylimide anion minimizes electrostatic ...

Superweak Coordinating Anion as Superstrong Enhancer of Cyanine Organic Semiconductor Properties

Frank Nüesch, Jakob Heier, Antonia Neels, Donatas Gesevicius

The superweak tetrakis(nonafluoro-tert-butoxy)aluminate coordinating anion was employed to introduce pseudo-gas-phase conditions to the 2-[5-(1,3-dihydro-1,3,3-trimethyl-2H-indol-2-ylidene)-1,3-pentadien-1-yl]-1,3,3-trimethyl-3H-indolium chromophore. The r ...

Light Scattering Enhancement at the Absorption Edge in Dewetting Droplets of Cyanine Dyes

Frank Nüesch, Jakob Heier, Florent Alexandre Boudoire

Diffraction properties of thin films of dewetted cyanine dye droplets are investigated and related to the complex refractive index. Strong changes in the index of refraction are often found near the absorption edge of organic dyes. Within a small window of ...
