Halogen bonds in 2D supramolecular self-assembly of organic semiconductors
Gutzler, Rico, Fu, Chaoying, Dadvand, Afshin, Hua, Yun, MacLeod, Jennifer M., Rosei, Federico, & Perepichka, Dmitrii F. (2012) Halogen bonds in 2D supramolecular self-assembly of organic semiconductors. Nanoscale, 4(19), pp. 5965-5971.
Weak interactions between bromine, sulphur, and hydrogen are shown to stabilize 2D supramolecular monolayers at the liquid–solid interface. Three different thiophene-based semiconducting organic molecules assemble into close-packed ultrathin ordered layers. A combination of scanning tunneling microscopy (STM) and density functional theory (DFT) elucidates the interactions within the monolayer. Electrostatic interactions are identified as the driving force for intermolecular Br⋯Br and Br⋯H bonding. We find that the S⋯S interactions of the 2D supramolecular layers correlate with the hole mobilities of thin film transistors of the same materials.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
