Using the density functional theory (DFT) method, the adsorption process of the \u03c0-systems on the investigated 2D sheets in the parallel configuration was observed to have proceeded more favorably than those in the vertical configuration. According to the observations of the Bader charge transfer analysis, the \u03c0-system\u2219\u2219\u2219sB complexes were generally recorded with the largest contributions of charge transfer, followed by the \u03c0-system\u2219\u2219\u2219\u03b212 and \u2219\u2219\u2219GN complexes. The band structures of the pure sheets signaled the metallic and semiconductor characters of the sB\/\u03b212 and GN surfaces, respectively. In the parallel configuration, the adsorption of both BNZ and HFB showed more valence and conduction bands compared to the adsorption in the vertical configuration, revealing the prominent preferentiality of the anterior configuration. The density-of-states (DOSs) results also affirmed that the adsorption process of the BNZ and HFB on the surface of the investigated 2D sheets increased their electrical properties. In all instances, the sB and \u03b212 surfaces demonstrated higher adsorptivity towards the BNZ and HFB than the GN analog. The findings of this work could make a significant contribution to the deep understanding of the adsorption behavior of aromatic \u03c0-systems toward 2D nanomaterials, leading, in turn, to their development of a wide range of applications.<\/jats:p>","DOI":"10.3390\/nano12061028","type":"journal-article","created":{"date-parts":[[2022,3,21]],"date-time":"2022-03-21T21:48:42Z","timestamp":1647899322000},"page":"1028","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Borophene and Pristine Graphene 2D Sheets as Potential Surfaces for the Adsorption of Electron-Rich and Electron-Deficient \u03c0-Systems: A Comparative DFT Study"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4819-2040","authenticated-orcid":false,"given":"Mahmoud A.
