The combination of Organic molecules and TiO2 surface is becoming a hot topic due to the extended use in novel photovoltaic devices. With this in mind, our group has studied several organic molecules on TiO2(110) surfaces. Thus, fullerenes, C<sub>60<\/sub>H<sub>30<\/sub>, Pentacene or PTCDI were studied by a combination of experimental and theoretical tools. Now, we expand that works in collaboration with the group of Luca Floreano (ALOISA beamline at Elettra synchrotron) by deeply characterizing Perylene, a prototypical molecule, on TiO2(110)-1&#215;1. By a combination of STM and UPS experiments together with an accurate \u201cmany-body\u201d corrected <em>ab initio<\/em> calculations we showed that the molecular coupling and adsorption configuration strongly depend on the coverage.<\/p>\n<ul>\n<li>&#8211; At low coverage, the surface-molecule interaction is dominated by van der Waals interactions. Perylene adsorb between O<sub>br<\/sub> of the TiO<sub>2<\/sub> surface with their large axis along the [001] crystallographic direction.<\/li>\n<li>&#8211; At high coverage the molecules self-organize forming large ordered domains. Under these conditions the interaction between molecules is found to be mediated by a strong side-to-side intermolecular hybridization.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><a href=\"https:\/\/wp.icmm.csic.es\/esisna\/wp-content\/uploads\/sites\/26\/2015\/04\/Perileno_ESISNA.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-2379 alignleft\" src=\"https:\/\/wp.icmm.csic.es\/esisna\/wp-content\/uploads\/sites\/26\/2015\/04\/Perileno_ESISNA.jpg\" alt=\"Perileno_ESISNA\" width=\"445\" height=\"269\" srcset=\"https:\/\/wp.icmm.csic.es\/esisna\/wp-content\/uploads\/sites\/26\/2015\/04\/Perileno_ESISNA.jpg 1156w, https:\/\/wp.icmm.csic.es\/esisna\/wp-content\/uploads\/sites\/26\/2015\/04\/Perileno_ESISNA-300x181.jpg 300w, https:\/\/wp.icmm.csic.es\/esisna\/wp-content\/uploads\/sites\/26\/2015\/04\/Perileno_ESISNA-768x464.jpg 768w, https:\/\/wp.icmm.csic.es\/esisna\/wp-content\/uploads\/sites\/26\/2015\/04\/Perileno_ESISNA-644x389.jpg 644w\" sizes=\"auto, (max-width: 445px) 100vw, 445px\" \/><\/a><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>The work has been published in <a href=\"http:\/\/pubs.acs.org\/doi\/abs\/10.1021\/acs.jpcc.5b00851\"><em>J.
