OSC devices, especially OLEDs, often consist of multiple layers comprising one or more species of organic molecules. The unique properties of each molecular species and their interaction determine charge transport in OSCs\u2014a key factor for device performance. The small charge carrier mobility of OSCs compared to inorganic semiconductors remains a major limitation of OSC device performance. Virtual design can support experimental R&amp;amp;D towards accelerated R&amp;amp;D of OSC compounds with improved charge transport. Here we benchmark a <jats:italic>de novo<\/jats:italic> multiscale workflow to compute the charge carrier mobility solely on the basis of the molecular structure: We generate virtual models of OSC thin films with atomistic resolution, compute the electronic structure of molecules in the thin films using a quantum embedding procedure and simulate charge transport with kinetic Monte-Carlo protocol. We show that for 15 common amorphous OSC the computed zero-field and field-dependent mobility are in good agreement with experimental data, proving this approach to be an effective virtual design tool for OSC materials and devices.<\/jats:p>","DOI":"10.3389\/fchem.2021.801589","type":"journal-article","created":{"date-parts":[[2021,12,24]],"date-time":"2021-12-24T05:00:39Z","timestamp":1640322039000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":14,"title":["De Novo Calculation of the Charge Carrier Mobility in Amorphous Small Molecule Organic Semiconductors"],"prefix":"10.3389","volume":"9","author":[{"given":"Simon","family":"Kaiser","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tobias","family":"Neumann","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Franz","family":"Symalla","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tobias","family":"Schl\u00f6der","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Artem","family":"Fediai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pascal","family":"Friederich","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wolfgang","family":"Wenzel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2021,12,24]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"165","DOI":"10.1016\/0009-2614(89)85118-8","article-title":"Electronic Structure Calculations on Workstation Computers: The Program System Turbomole","volume":"162","author":"Ahlrichs","year":"1989","journal-title":"Chem.
