Diphenylfumaronitrile-based alternating copolymer (DPFN-DPPF) combined with a furan-substituted diketopyrrolopyrrole-fused aromatic conjugated building block is reported. DPFN-DPPF exhibits a band-gap of 1.53 eV with a lower highest occupied molecular orbital (HOMO) value of 5.50 eV. A bottom-contact bottom-gate organic thin-film transistor device fabricated using DPFN-DPPF thin film exhibits a hole mobility of 0.20 cm2 V−1 s−1 in air.

A series of half-titanocene analogs is synthesized and used for the synthesis of syndiotactic poly(styrene) (st-PS). High-molecular-weight st-PS with values up to 1 400 000 g mol−1 (polydispersity index (PDI) = 1.38) is prepared with activities up to 5000 kgst-PS molcat−1 h−1.

Four novel well-defined polyethylene-bound antioxidants with distinct secondary structures, which show higher thermal stabilities and reasonably high antioxidant efficiencies compared with the commercial antioxidant Irganox1076, are synthesized via transesterification reactions between methyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate and hydroxyl-terminated polyethylenes.
- Michler's Ketone as an Interesting Scaffold for the Design of High-Performance Dyes in Photoinitiating Systems Upon Visible Light
Haifaa Mokbel, Frédéric Dumur, Bernadette Graff, Cédric R. Mayer, Didier Gigmes, Joumana Toufaily, Tayssir Hamieh, Jean-Pierre Fouassier and Jacques Lalevée
Article first published online: 4 MAR 2014 | DOI: 10.1002/macp.201300779
Four new push–pull dyes derived from Michler's ketones are presented. These dyes are based on a donor–π–acceptor (D–π–A) structure and exhibit a tunable character according to the electron-withdrawing ability of the acceptor used. The new proposed structures can be used in high-performance photoinitiating systems.
- Surface-Initiated RAFT Polymerization of Clay Nanoparticles with Polystyrene: New Insights Using MALDI-TOF MS and 1H NMR
Helen Chirowodza, Patrice C. Hartmann and Harald Pasch
Article first published online: 4 MAR 2014 | DOI: 10.1002/macp.201400013
Reversible addition-fragmentation chain transfer (RAFT)-mediated grafting of polystyrene from clay is investigated using advanced analytical methods. The chain-end structures of the grafted polymer grown from the clay surface and the free polymer chains are investigated. Information on the grafted and nongrafted macromolecules provides additional new insight into the polymerization mechanism.
