A novel n‐type dimer dopant for semiconducting polymers

Polymer International, EarlyView.
A novel molecular n‐type dopant (1) with superior capacity to dope conjugated polymers is introduced. After charge transfer the product (2) remains in the polymer. Abstract Efficient and stable doping of organic semiconductors is crucial for adjusting their electrical properties.

Adsorption of Metallocenes on Silica

Chemistry – A European Journal, 2016
AbstractThe adsorption of the metallocenes ferrocene, doubly deuterated ferrocene, cymantrene and nickelocene, as well as molybdenum hexacarbonyl, proceeds in the absence of a solvent. Large single pieces of silica gel were placed in contact with the solid metallocenes and the adsorption process was visualized on a macroscopic scale and the maximal ...

The influence of long chain branches of LLDPE on processability and physical properties

Polímeros, 2015
Two polyethylene-based on single-site metallocene catalyst (mLLDPE) were selected to characterize the effect of long chain branching (LCB) on blown film processability, optical and mechanical properties.

Das fehlende Glied der Ferrocenophan‐Chemie: Isolierung eines Carba[1]Ferrocenophans

Angewandte Chemie, Volume 138, Issue 34, 17 August 2026.
Die Synthese und Isolierung eines kristallinen Carba[1]Ferrocenophans wird berichtet. Ein einzelnes Kohlenstoffatom ist das bislang kleinste Verbrückungsmotiv, das in ein Ferrocenophan eingebaut werden konnte. Dies resultiert in einem Diederwinkel der Ebenen der Cyclopentadienylringe von 36.7°, was entsprechend die größte Abwinkelung relativ zu ...

Alargamento da distribuição de massa molar de polímeros sintetizados com catalisadores metalocênicos dual-site Broadening of molecular weight distribution of polymers synthesized by metallocene-based dual-site catalysts

Química Nova, 2008
The main topics related to the use of dual-site catalysts in the production of polymers with broad molecular weight distribution are reviewed. The polymerization using dual-site catalysts is more economical and allows to produce a higher quality product ...

The Missing Link in Ferrocenophane Chemistry: Isolation of a Carba[1]Ferrocenophane

Angewandte Chemie International Edition, Volume 65, Issue 34, 17 August 2026.
The synthesis and isolation of a crystalline carba[1]ferrocenophane is reported. A single carbon atom is the smallest bridging motif yet incorporated into a ferrocenophane, resulting in a dihedral angle between the cyclopentadienyl ring planes of 36.7°, which is the highest angular deflection from ferrocene's coplanarity observed so far.

Synthesis and Antiparasitic Activities of New Organometallic Derivatives of the Benzimidazole Anthelmintic Drugs

ChemBioChem, Volume 27, Issue 15, 14 August 2026.
Organometallic derivatization of existing drugs is a common strategy to look for new drug candidates. This work describes the derivatization of the benzimidazole anthelmintic scaffold, from the synthesis of the organometallic derivatives to the evaluation of their biological properties. It highlights a broad range of antiparasitic activities and leaves
