Fluorination can be used to tune optoelectronic properties at the mol. level. A series of oligophenyls with various difluorinations of the Ph rings has been synthesized, crystalized, structurally resolved and computationally analyzed for charge mobility. We find that difluorination of the Ph rings at para positions leads to oligophenyls that are stacked in sym. overlap with significantly enhanced hole mobility as well as the highest electron mobility of the mols. considered. Other difluorinations lead to relatively shifted mol. units in the π-stacked crystal and therefore to lower mobilities. The selectively fluorinated oligophenyls were synthesized using the Suzuki-Miyaura cross coupling reaction. The structures of the products were characterized by X-ray diffraction (XRD), 1H, 13C, 19F NMR spectroscopy and gas chromatog. (GC)/mass spectroscopy (MS) measurements. Computational anal. of the materials based on state-of-the-art tools are used to predict their charge transport properties in the crystal phase. In short, we establish a mol. design approach based on fluorination of oligophenyls to achieve enhanced hole mobilities and relatively high electron mobilities. In the experiment, the researchers used many compounds, for example, 1,2-Difluoro-3-iodobenzene (cas: 64248-57-3Recommanded Product: 64248-57-3).
1,2-Difluoro-3-iodobenzene (cas: 64248-57-3) belongs to iodide derivatives. Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles. Polyiodoorganic compounds are sometimes employed as X-ray contrast agents, in fluoroscopy, a type of medical imaging. This application exploits the X-ray absorbing ability of the heavy iodine nucleus.Recommanded Product: 64248-57-3
