Effects of Molecular Weight on Microstructure and Carrier Transport in a Semicrystalline Poly(thieno)thiophene

Kevin Sivula, Andrea Gasperini

The ultimate control over chain self-assembly is key to unravel and optimize the relationship between film microstructure and charge carrier mobility in solution processable conjugated polymer semiconductors. Here we employ preparatory size exclusion chrom ...

Comparative Study on the In Vitro Cytotoxicity of Linear, Dendritic, and Hyperbranched Polylysine Analogues

Harm-Anton Klok, Florian Maria Wurm, David Hacker, Lucia Baldi Unser, Zuzana Kadlecova

Lysine-based polycations are widely used as nonviral carriers for gene delivery. This manuscript reports the results of a comparative study on the in vitro cytotoxicity of a library of three structural polylysine variants, namely, linear polylysine (LPL), ...

Functional, Hyperbranched Polyesters Via Baylis-Hillman Polymerization

Harm-Anton Klok, Frederik Roman Wurm, Sanhao Ji

Hyperbranched polyesters are among the most common hyperbranched polymers. One of the interesting features of hyperbranched polyesters is that they contain unreacted hydroxyl and carboxylic acid groups at the linear and terminal structural units, which can ...

Polymerization of the new double-charged monomer bis-1,3(N,N,N trimethylammonium dicyanamide)-2-propylmethacrylate and ionic conductivity of the novel polyelectrolytes

Jutta Christine Wandrey

The achievement of high ionic conductivity in single-ion conducting polymer electrolytes is one of the important aims for various electrochemical devices including modern lithium batteries. One way to enhance the ionic conductivity in polyelectrolyte syste ...

Exploring the Scope of the Baylis-Hillman Reaction for the Synthesis of Side-Chain Functional Polyesters

Harm-Anton Klok, Sanhao Ji

The BaylisHillman reaction provides a protective-group-free strategy to heterobifunctional polyesters, which can be further modified via various post-polymerization modification reactions. This contribution explores the BaylisHillman polymerization of 1,3- ...

Synthesis of Pyridyl Disulfide-Functionalized Nanoparticles for Conjugating Thiol-Containing Small Molecules, Peptides, and Proteins

Jeffrey Alan Hubbell

Previously we reported emulsion polymerization of propylene sulfide with Pluronic F127 as an emulsifier, yielding nanoparticles (NPs) in the 25 nm size range. Immunologically functional NPs were prepared by adding an antigen Pluronic conjugate to the polym ...

Synthesis of Functional Polydepsipeptides via Direct Ring-Opening Polymerization and Post-Polymerization Modification

Harm-Anton Klok, Nadja Franz

This contribution explores different strategies for the synthesis of side chain functional polydepsipeptides. First, the ring-opening polymerization of side chain functional morpholine-2,5-diones is revisited and the optimized reaction conditions used for ...
