Disclosed herein is a novel method for preparing cyclophanes, comprising forming a disulfide cyclophane by contacting a linker moiety which includes two or more thiol groups, with a metal salt and an oxidant. The disulfide cyclophane is then desulfurized to form a thiacyclophane comprising thioether bridges. This thiacyclophane optionally may be further desulfurized to form an unsaturated hydrocarbon cyclophane, which can then be reduced to form a saturated hydrocarbon cyclophane. The various cyclophanes can be synthesized in a ring form, such as a dimer, trimer or tetramer etc., or they can be synthesized in a tetrahedral or larger structure. Also disclosed are novel cyclophanes formed by the disclosed method.

Cu2+ salts are presented as an alternative to previously reported pnictogen additives in the self-assembly of 23 different thiacyclophanes. This process allows for further tuning of library equilibrium mixtures: for instance, by altering additive types and concentrations, trimeric macrocycles are amplified. These trimeric disulfides can then be covalently trapped to form 2 novel thioethers, highlighting

The synthesis of [2.2](4,4′) benzophenono (2,6) naphthalenophane (1), the parent member of a series of stacked sensitizer-acceptor cyclophanes, is reported along with its x-ray structure and the absorption and emission spectra.
to a simple access to triple-layered [2.2][2.2]paracyclophane. Its structure was elucidated by X-ray crystallographic analysis. The outer naphthalene rings are bent into a boat form and the inner naphthalene ring is bent into a twist form. These naphthalenes are stacked in layers within van der Waals contact. Therefore, there is a strong transannular π-electronic interaction between them, which brings
