On the Role of Single Regiodefects and Polydispersity in Regioregular Poly(3-hexylthiophene): Defect Distribution, Synthesis of Defect-Free Chains, and a Simple Model for the Determination of Crystallinity

TL;DR: This work shows that the most commonly used synthetic protocol for the synthesis of P3HT, the living Kumada catalyst transfer polycondensation (KCTP) with Ni(dppp)Cl(2) as the catalyst, leads to regioregular chains with one single tail-to-tail defect distributed over the whole chain, in contrast to the hitherto assumed exclusive location at the chain end.
Journal ArticleDOI
1H multiple-quantum nuclear magnetic resonance investigations of molecular order distributions in poly(dimethylsiloxane) networks: Evidence for a linear mixing law in bimodal systems
Kay Saalwächter,Pascal Ziegler,Olivier Spyckerelle,Bassel Haidar,Alain Vidal,Jens-Uwe Sommer +5 more
TL;DR: In this article, a robust pulse sequence characterized by a well-defined doublequantum Hamiltonian along with a specific normalization approach is used to obtain double-quantum build-up curves.
Journal ArticleDOI
Properties of Dendrimers with Flexible Spacer-Chains: A Monte Carlo Study
TL;DR: In this paper, the properties of starburst dendrimers with flexible spacers in good solvent using Monte Carlo simulations based on the bond fluctuation model by systematic variation of the generation number G and spacer length S were investigated.
Book
Polymer crystallization : observations, concepts and interpretations
Günter Reiter,Jens-Uwe Sommer +1 more
TL;DR: In this article, a generic model for growth and morphogenesis of polymers in two dimensions is presented, with a coarse-grained model based on a DSC approach, and the effects of flow-induced Crystallization are investigated.
Journal ArticleDOI
Nanoscale brushes: how to build a smart surface coating.
TL;DR: It is demonstrated that the combination of a high grafting density, an inflated end-group size, and a high degree of monodispersity is a condition for an optimal functionality of the switch.
