- D-π-A Conjugated Molecules for Optoelectronic Applications
Tae-Dong Kim and Kwang-Sup Lee
Article first published online: 27 MAR 2015 | DOI: 10.1002/marc.201400749
This article provides a brief review of the current status of research related to D-π-A dipolar chromophores together with a description of their syntheses and several promising applications in related fields. Structure/property relationships are discussed in order to exploit the potentials by tuning the π-electron density, polarizability, and HOMO–LUMO band gap of the chromophores.
- Synthesis and Conformation of 3,6-Connected Cyclohexadiene Chains
Florian E. Golling, Amelie H. R. Koch, George Fytas and Klaus Müllen
Article first published online: 27 MAR 2015 | DOI: 10.1002/marc.201400712
The synthesis of novel 3,6-dimethoxycyclohexadiene oligomers is reported. Their structure is investigated by density functional theory calculations and dynamic light scattering measurements, confirming the formation of linear and rigid chains, which allow for the synthesis of poly(para-phenylene) derivatives.
- Aminobisphosphonate Polymers via RAFT and a Multicomponent Kabachnik–Fields Reaction

Aminobisphosphonate polymers are synthesized via reversible addition-fragmentation chain transfer polymerization and multicomponent reactions. Polymerization of a protected amine monomer results in good control over molecular weights and polydispersity indices (PDIs). The deprotected amine is reacted with a phosphite and an aldehyde to install the aminobisphosphonate moiety.
- Synthesis and Application of Nanohybrids Based on Upconverting Nanoparticles and Polymers

Lanthanide-doped upconversion-luminescent nanoparticles serve as transducer for converting near-infrared light to shorter wavelength radiation. The unique optical properties of upconversion-luminescent nanoparticles make them promising candidates for a new class of luminescence probe in widespread applications such as luminescent labeling, displays, bioimaging, bioassays, drug delivery, sensors, and anticounterfeiting. In each field, polymers play an irreplaceable role and have been proven to be very useful from synthesis to surface modifications and further functionalization for upconversion-luminescent nanoparticles. Therefore, this article will focus on upconversion-luminescent nanoparticles/polymer nanohybrids and their new interesting fruits in applications.
- Recent Advances in Gas Barrier Thin Films via Layer-by-Layer Assembly of Polymers and Platelets
Morgan A. Priolo, Kevin M. Holder, Tyler Guin and Jaime C. Grunlan
Article first published online: 19 MAR 2015 | DOI: 10.1002/marc.201500055
This Feature Article reviews multilayer thin films, deposited layer-by-layer to produce a ‘nanobrick wall’ structure that imparts high gas barrier to permeable polymer substrates. These transparent, water-based thin films exhibit a lower permeability than any other barrier thin film material.
