“…The overall aromatic system is nearly planar with a dihedral angle of 8.0(3)° between the catechol and the central pyridine ring [C7‐C8‐C18‐C19]. Similar results were obtained for (4‐pyridyl)acetylene‐substituted benzo[18]crown‐6 29. The spacer triple bond [C16‐C17] is 1.191(8) Å long, whereas the adjacent [C8C16] and [C17C18] bond lengths are 1.442(8) and 1.435(8) Å, in line with conjugation.…”

Coordination-driven self-assembly of differently shaped di- to hexavalent crown-ether host molecules is described. A series of [21]crown-7- and [24]crown-8-substituted bipyridine and terpyridine ligands was synthetized in a "toolbox" approach. Subsequent coordination to 3d transition metal and ruthenium(II) ions provides an easy and fast access to host assemblies with variable valency and pre-defined orientations of the crown-ether moieties. Preliminary isothermal calorimetry (ITC) titrations provided promising results, which indicated the host complexes under study to be suitable for the future investigation of multivalent and cooperative binding. The hosts described herein will also be suitable for the construction of various multiply threaded mechanically interlocked molecules.

The author’s data (2000-2022) on synthesis methods, reactivity and applied aspects of aryl- and hetarylacetylenes were summarized. The specificity of alkynylarenes (hetarenes) associated with the activation of the triple bond by acceptor groups were noted. Particular attention was paid to fundamentally important new reactions of heterocyclization and complete soft cleavage of the triple bond. The prospects for the use of alkynylarenes and -hetarenes and their modification products were reflected. The results of screening of the synthesized compounds were presented.
