Synthesis of Alkyl Chain Spacer in A-D-A n-type dominant Semiconductors |
| 초록 |
Although the effects of alkyl chain spacers have been intensively studied for p-type conjugated polymers with a donor (D)– acceptor (A) repeating unit, few studies have examined their effects for n-type polymers with an A–D–A architecture having two different acceptors in the repeating unit. Due to the strong electron deficiency and trans-planar conformation, DPPBTz-based polymer semiconductors exhibit n-type dominant electrical properties with high electron mobility up to 1.87 cm2 V-1s-1. Systematic study on the photophysical properties, thin-film microstructures, and electrical properties of the DPPBTz polymers reveals that, upon modification of the branching position, A–D–A n-type dominant semiconductors behave differently compared with D–A p-type dominant semiconductors, due to their relatively weaker intermolecular interactions, making the C1 spacer more efficient for electron transport. |
