AI Article Synopsis
- Researchers used 1-Hexyne monomers in a confined 1D metal-organic framework (Cu(BDC)) to create conductive polymer layers through an electropolymerization process.
- A layer-by-layer method enabled them to deposit the framework on patterned electrodes, allowing for real-time measurement of electrical conductivity without removing the polymer film.
- They confirmed successful polymerization with mass spectroscopy and found that the conductivity increased by 8 orders of magnitude, with DFT calculations suggesting that electron hopping between oligomers limits final conductivity.
Article Abstract
1-Hexyne monomers were potentiostatically electropolymerized upon confinement in 1D channels of a surface-mounted metal-organic framework Cu(BDC) (SURMOF-2). A layer-by-layer deposition method allowed for SURMOF depostition on substrates with prepatterned electrodes, making it possible to characterize electrical conductivity in situ, i.e., without having to delaminate the conductive polymer thin film. Successful polymerization was evidenced by mass spectroscopy, and the electrical measurements demonstrated an increase of the electrical conductivity of the MOF material by 8 orders of magnitude. Extensive DFT calculations revealed that the final conductivity is limited by electron hopping between the conductive oligomers.
