- ¿Conjugated? Copolymers from a Pechmann Dye Derivative
A. D. Thilanga Liyanage, Begoña Milián-Medina, Bei Zhang, Johannes Gierschner and Mark D. Watson

The optical properties of “donor–acceptor” copolymers of an amidated Pechman dye (APD) are dictated almost completely by the APD unit alone. Quantum chemical studies reveal the cause to be the location of APD's HOMO–LUMO gap within those of common donors, giving examples of the fifth of five general outcomes of the donor–acceptor approach.
- Confinement Effects on the Optical Properties and Chain Conformations of Poly(9,9-di-n-octylfluorene-alt-benzothiadiazole) Nanotubes

Confinement effects on the optical properties and chain conformations of poly(9,9-di-n-octylfluorene-alt-benzothiadiazole) (F8BT) nanotubes are studied. The nanotubes are fabricated by a solution wetting method using anodic aluminum oxide templates. The spectroscopy data indicate that F8BT polymer chains have less intermolecular interactions and coplanarity under the confinement effect.
- Bicolored Janus Microparticles Created by Phase Separation in Emulsion Drops
Nam Gi Min, Tae Min Choi and Shin-Hyun Kim
Version of Record online: 22 JUL 2016 | DOI: 10.1002/macp.201600265
Janus microparticles are prepared by phase separation of two immiscible polymers confined in emulsion drops. Spontaneous staining of selected compartment by dyes renders the microparticles bicolored. Magnetic nanoparticles embedded in the polymer matrix provide a net magnetic moment on the microparticles. Janus microparticles with optical and magnetic anisotropy can be potentially used as active color pigments for reflection-mode displays.
- A Biodegradable and Amphiphilic Linear-Dendritic Copolymer as a Drug Carrier Platform for Intracellular Drug Delivery
Haibo Wang, Yan Wu, Gongyan Liu, Zongliang Du and Xu Cheng
Version of Record online: 21 JUL 2016 | DOI: 10.1002/macp.201600269
A biodegradable linear-dendritic copolymer as a drug delivery platform is synthesized successfully. The polymer drug delivery system is internalized effectively by cancer cells and releases DOX rapidly at endosomal pH.
- Imaging of Polymeric Nanoparticles: Hard Challenge for Soft Objects
Paricia Renz, Maria Kokkinopoulou, Katharina Landfester and Ingo Lieberwirth

The visualization of polymeric nanoparticles by means of electron microscopy methods is an important mainstay for the characterization. Simple drop casting is a commonly used preparation method but it meanly conserves the nanoparticle morphology. Alternatively, the nanoparticles can be embedded into a matrix consisting of trehalose or ionic liquid in order to achieve a better structure conservation.
