Moreover, all the documentation is now updated and available at a dedicated website, where tutorials, templates and additional tools can be downloaded together with the code, hence making JOYCE3.0 a well-documented and user-friendly tool for accurate QMD-FF generation of varied materials. The aim of this paper is therefore three-fold: i) review and rationalize in a Figure : Structure of the molecular targets considered in the present work. From a) to g): I: triperyleno [3,3,3] propellane, II: poly(2,7-pyrenylene), III: n-tetradecane, IV: ethylene terephtalate, V: 11cis retinal protonated Schiff base (rPSB11), VI: N',N"-propylenebis(salicylaldiminato)nickel(II) ([Ni(salpn)]) complex, VII: dithiophene. In all cases, cyan, white, red, blue, brown and yellow spheres are employed for Carbon, Hydrogen, Oxygen, Nitrogen, Nichel and Sulfur atoms, respectively.
