Front Cover: Zinc metal coordination of a 9H-carbazole bearing terpyridines at the 3- and 6-positions produces a pentamer that shows excitation-wavelength-dependent emission in solution, and order in the solid state due to H-bonding. Complexation of the corresponding 9-alkylcarbazole derivatives produces a mixture of oligomers with a totally different behavior. Further details can be found in the article by Y. Gao, T. He, P. Hu, T. M. Koh, H. Sun, and A. C. Grimsdale* on page 753.

Thermoresponsive microgels with controlled, varying internal polymer-network heterogeneity exhibit very similar macroscopic equilibrium swelling and deswelling, in quantitative agreement with mean-field predictions, independent of their internal nanometer-scale homogeneity or heterogeneity.
- A Novel SiO2-Supported Cr–V Bimetallic Catalyst Making Polyethylene and Ethylene/1-Hexene Copolymers with Bimodal Molecular Weight Distribution

A novel SiO2-supported Cr–V bimetallic catalyst for ethylene polymerization and ethylene/1-hexene copolymerization is systematically investigated. It is found that the addition of V species in the S-2 catalyst is an effective way to increase the ethylene polymerization yield, obtain bimodal molecular-weight-distribution (MWD) copolymers, and improve the short-chain branch distribution (SCBD) of the high-density polyethylene (HDPE) products.
