In this study, a new chiral α,ω-bifunctional polythiophene is synthesized and used as a nanoparticle linker molecule to synthesize the first layered conjugated polymer/nanoparticle (CP/NP) hybrid m...

The supramolecular organization of star-shaped polythiophenes was investigated in a solvent/nonsolvent system and upon cooling. Both systems yield entirely different supramolecular aggregates. Classical characterization techniques can give some insight; the exact mechanism is currently not understood. By introducing second- and third-harmonic light scattering and its combination with other optical techniques, we were able to fully investigate ...

Poly(thiophene)s have an inherently large third-order nonlinear optical (TONO) response, but applications are not straightforward due to unoptimized materials. Therefore, several structure-property relationships (molar mass, branching, regioregularity) are investigated to unravel which structural modifications give the highest TONO response. Poly(3-hexylthiophene) with different molar masses, poly[3-(2-ethylhexyl)thiophene] with different molar ...

Due to their capability of film formation and remarkable optical features, semiconductor polymers with high two-photon absorption (2PA) have been studied as potential candidates for the development of organic photonic platforms. Furthermore, there is a high demand for photonic devices operating in the near-infrared (IR) region. However, the magnitude of the nonlinear optical response of random coil polymers in the IR region is weak due to the ...
