To further understand the fundamental effects related to increasing strain and differing reactivity of monomers in these types of molecules, unsymmetrical dithiols were synthesized and subjected to disulfide formation conditions with Sb(III) or Cu(I) directing agents to give a library of novel self\u2010assembled macrocycles. From these libraries, a slight preference towards narcissistic aryl\u2013aryl and alkyl\u2013alkyl disulfide linkages was observed, when other more stabilizing\/destabilizing factors (such as dihedral strain, \u03c0\u2013\u03c0 interactions, etc.) were not in play. This study shows that while this weak electronic preference biases formation of narcissistic disulfide formations at early reaction times, this bias can easily be overcome by steric or electronic stabilizing effects within the assemblies when allowed more time to equilibrate. This leads to significant amplification of one species over others. Further, an interesting preference of Sb(III)\u2010assisted assembly for narcissistic disulfide linkages was observed, which may suggest a more complicated role in antimony\u2010related cascade reactions and pnictogen\u2010thiolate\/disulfide interplay that could have relevance in associated disease states and intracellular uptake.<\/jats:p>","DOI":"10.1002\/chem.71800","type":"journal-article","created":{"date-parts":[[2026,10,16]],"date-time":"2026-10-16T04:36:10Z","timestamp":1792125370000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Cyclic
