This aromatic regioisomer-driven strategy has been used with a cholesterol-based gelator to prepare hollow self-assembled organic nanotubes (S-ONTs) with inside and outside diameters of ca. 35 and 140 nm, respectively. Electron microscopy imaging and theoretical calculations were employed to rationalize the formation mechanism of these S-ONTs. From the three possible regioisomers, only the ortho-disubstituted cholesteryl-based gelator showed the optimal angle and distance between substituents to afford the formation of the cyclic assemblies required for nanotube growth by assembling 30–40 units of the gelator. This study opens fascinating opportunities to expand the synthesis of controllable and unique microstructures by modulating geometrical parameters through aromatic regioisomers. 000095637 536__ $$9info:eu-repo/grantAgreement/ES/DGA-FSE/E07-20R$$9info:eu-repo/grantAgreement/ES/MCIU/RED2018-102471-T$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/CTQ2017-88091-P 000095637 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000095637 590__ $$a2.863$$b2020 000095637 591__ $$aCHEMISTRY, MULTIDISCIPLINARY$$b95 / 178 = 0.534$$c2020$$dQ3$$eT2 000095637 592__ $$a0.801$$b2020 000095637 593__ $$aChemistry (miscellaneous)$$c2020$$dQ1 000095637 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000095637 700__ $$0(orcid)0000-0002-5244-9569$$aPérez Herrera, Raquel$$uUniversidad de Zaragoza 000095637 700__ $$aDíaz Díaz, D. 000095637 7102_ $$12013$$2765$$aUniversidad de Zaragoza$$bDpto.
