- Synthesis and Optoelectronic Properties of Novel Polyamides with 2-Naphthyldiphenylamine Units
Sheng-Huei Hsiao and Su-Jung Yeh
Article first published online: 12 MAR 2014 | DOI: 10.1002/macp.201400002
The synthesis and characterization of new redox-active polyamides containing N,N′-di-2-naphthyl-N,N′-diphenyl-1,4-phenylenediamine segments is described. All the polyamides have good solubility in many polar aprotic solvents and can be cast into flexible and strong films. In addition to high Tg and high thermal stability, the polymers also reveal interesting electrochromic characteristics with multi-electrochromic behavior (highly transmissive-to-green and then to-blue switching).

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.
- Stereospecific Styrene Polymerization by Methylalumoxane-Activated Ti (IV) N-Trimethylsilylamido Complexes Bearing the N-Biphenyl or N-(6-(2-(Diethylboryl)phenyl)-Pyrid-2-yl) Motif

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.
- Synthesis and Properties of Polyethylene-Bound Antioxidants

Article first published online: 5 MAR 2014 | DOI: 10.1002/macp.201300749
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.
