Fecha de publicación: | 2013 | Editor: | American Chemical Society | Citación: | Chemistry of Materials 25(22): 4503-4510 (2013) | Resumen: | Iodoalkynes [1,4-bis(iodoethynyl)benzene (p-BIB) and 1,3-bis(iodoethynyl) benzene (m-BIB)] have been used successfully to prepare halogen bonding complexes with a range of 4-pyridine derivatives showing liquid crystalline organizations. The trimeric halogen-bonded complexes obtained from p-BIB have a rod-like structure and exhibited high order calamitic phases (SmB and G). In contrast, m-BIB gives rise to bent-shaped structures that display SmAP-like mesophases. Furthermore it was found that the presence of three and five aromatic rings in these halogen-bonding complexes promotes calamitic mesophases while seven rings are required to stabilize bent-core mesophases. The formation of halogen bonding in the complexes was confirmed by several techniques, including FT-IR, XPS, and single crystal X-ray diffraction and the strength of the bonds was evaluated by DFT calculations © 2013 American Chemical Society. | URI: | http://hdl.handle.net/10261/117619 | DOI: | 10.1021/cm401849f | Identificadores: | doi: 10.1021/cm401849f issn: 0897-4756 e-issn: 1520-5002 |
