Global Analysis of Polyfluorene via AB-Type Suzuki–Miyaura Polymerization : Empirical and Mechanistic Rationalization of…

The preparation of conjugated polymers with precisely tunable optoelectronic properties is based on modern polymerization techniques. In addition to conventional step-growth polycondensation for the underlying C–C coupling steps, the Suzuki-Miyaura catalyst-transfer polymerization (SCTP) continues to…

Pyrazine‐Functionalized Ru(II)‐Complexes as Visible‐Light Activated Photobases

Excited‐state proton transfer (ESPT) roots in significantly increased acidities or basicities of up to ca. 10 p K a units in the excited state compared to the ground state. While organic photobases are either of “single use” in the case of photobase generators or are limited functionally by their UV…

From Molecular to Polymeric Donors: Prolonged Charge Separation in Modular Photoredox-Active Ru(II) Polypyridyl-Type Triads

In this contribution, the divergent modular synthesis of photoredox-active dyads, triads and a tetrad descending from one ligand precursor is presented by combining “chemistry-on-the-ligand”, stepwise complexation and “chemistry-on-the-complex” with minimal synthetic efforts. In the final step, Pd-mediated…

Low-Pressure Preparative Size-Exclusion Chromatography : from Narrow Disperse Polymer to Monodisperse Oligomer Batches

Redox-active conjugated oligo(quinoxaline)s as potential visible light-transparent charge transport building blocks were synthesized, purified, and characterized. The Suzuki–Miyaura catalyst-transfer polymerization (SCTP) in the presence of an excess of monofunctional aryl halide led to quantitative…

Exploiting Orthogonal C–C Cross-Coupling Reactions for Chemistry-on-the-Complex: Modular Assembly of 2,6-Di(quinolin-8-yl)pyridine…

In this work, we present a concise modular assembly strategy using one universal heteroleptic 2,6-di(quinolin-8-yl)pyridine-based ruthenium(II) complex as a starting building block. Extending the concept from established ligand modifications and subsequent complexation ( classical route ), the later…

Adaptation of electrodes and printable gel polymer electrolytes for optimized fully organic batteries

Abstract Despite intensive scientific efforts on the development of organic batteries, their full potential is still not being realized. The individual components, such as electrode materials and electrolytes, are in most cases developed independently and are not adjusted to each other. In this context,…
