Issue Date: | 2016 | Source: | MACROMOLECULES, 49(17), p. 6411-6419 | Abstract: | Although controlled polymerization procedures for conjugated polymers have considerable advantages with respect to molar mass and end group control, the material scope has been very limited, in particular considering block copolymers and donor–acceptor type all-conjugated polymers, imposing considerable challenges upon the synthetic polymer community. In this work, a push–pull monomer consisting of a thiophene (donor) and a pyridine (acceptor) unit is synthesized and subsequently polymerized via Kumada catalyst-transfer polymerization using a nickel catalyst (GRIM polymerization). In this way, an alternating donor–acceptor copolymer is obtained via a chain-growth mechanism. Furthermore, an all-conjugated block copolymer containing a poly(3-hexylthiophene) block and the alternating copolymer is successfully prepared in a one-pot procedure as well. The diblock structure is confirmed by comparison of the thermal, electrochemical, and spectroscopic properties of the block copolymer and its constituting polymer parts. | Document URI: | http://hdl.handle.net/1942/23008 | ISSN: | 0024-9297 | e-ISSN: | 1520-5835 | DOI: | 10.1021/acs.macromol.6b01389 | ISI #: | 000383318300028 | Rights: | © 2016 American Chemical Society | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2017 |
