Effect of polycyclosilane microstructure on thermal properties
Magnesium bromide (MgBr2) as a catalyst for living cationic polymerization and ring-expansion cationic polymerization
Magnesium bromide (MgBr2) was found to be an effective catalyst for the ring-expansion cationic polymerizations of isobutyl vinyl ether (IBVE) initiated by a “cyclic” hemiacetal ester (HAE) bond-based initiator leading to the syntheses of cyclic poly(IBVE)s.
Sequence-regulated vinyl polymers via iterative atom transfer radical additions and acyclic diene metathesis polymerization
Iterative ATRAs and ADMET polymerization enabled the synthesis of sequence-regulated vinyl polymers without statistical distribution of monomer compositions and sequences.
Facile C–H iodination of electron deficient benzodithiophene-S,S-tetraoxide for the development of n-type polymers
A C–H iodination reaction of the electron-poor building block, benzo[1,2-b:4,5-b0]-dithiophene-1,1,5,5-tetraoxide has been reported. This facile functionalization has led to the development of two novel n-type donor–acceptor conjugated polymers.
Sequence-defined L-glutamamide oligomers with pendant supramolecular motifs via iterative synthesis and orthogonal post-functionalization
One of the great challenges in polymer chemistry is to achieve discrete and sequence-defined synthetic polymers that fold in defined conformations and form well-defined three-dimensional structured particles.
Analysis of cyclic polymer purity by size exclusion chromatography: a model system
Because cyclic polymers have intriguing physical properties, considerable synthetic strategies have been developed to create a wide variety of cyclic architectures.
Stereocontrolled, multi-functional sequence-defined oligomers through automated synthesis
In this work, stereocontrolled sequence-defined oligomers were prepared using an automated thiolactone-based platform that allows post-synthesis functionalisation.
Discrete multifunctional sequence-defined oligomers with controlled chirality
New synthetic strategy leading to discrete poly(triazole-urethane) oligomers with a large range of functional side groups, programmable stereochemistry and sequentiality.
About this collection
This special issue, Molecularly Defined Polymers: Synthesis and Function, Guest Edited by Professor Filip Du Prez (Ghent University), Professor Jeremiah Johnson (MIT) and Professor Elizabeth Elacqua (Penn State University), presents the latest developments in the synthesis and applications of polymers with controlled, defined and/or precise molecular-scale structures. New strategies for the synthesis of synthetic polymers with molecularly defined structures promise to enable a new era of functional materials.
Examples include methods to control atomic connectivity (i.e. sequence control/definition), three-dimensional functional group presentation (i.e. stereochemistry/tacticity), conformation (e.g. secondary or higher-order structure) and combinations of these features in synthetic polymers. These features can impact specific functions such as mechanical properties, self-assembly, information storage or interactions with biological systems.
