“…21,22 Grant group have reported a diruthenium(II) complex of 12-tetrathia-crown-4 (12S4), {[Ru(12S4)] 2 (μ-bpy)}, linked with 4,4-bipyridyl (bpy). 21 We have reported several dumbbell-type disilver(I) complexes of oxathiamacrocycles linked with different diamine spacers such as dabco (1,4-diazabicyclo[2,2,2]octane, bpy, bpp (1,4-bis(4pyridyl)piperazine). 22 The preparations of the dumbbell-type macrocyclic complexes with inorganic linkers are serendipitous because they are associated with the cluster formations which are hardly predictable.…”

A 20-membered NOS-macrocycle (L) and a 40-membered NOS-macrocycle (L) were employed as a [1:1] and a [2:2] cyclization product, respectively, for the preparation of diverse types of supramolecular complexes including a cascade complex. Six complexes (1-6) of the smaller macrocycle L including discrete to continuous forms, mono- to heteronuclear, and endo- to exo- and endo/exocoordination were prepared and their coordination modes were discussed systemically. First, the reaction of L with CuI in the presence of trifluoroacetic acid afforded an exocyclic 1-D coordination polymer {[(μ-CuI)(HL)](CFCOO)} (1). Meanwhile, the reaction of L with Cu(ClO)·6HO afforded a typical endocyclic mononuclear complex [Cu(L)](ClO)·HO (2). In the reactions of L with CdX (X = Br and I), isostructural sandwich-type complexes [Cd(L)Br] (3) and [Cd(L)I] (4) were isolated. The treatment of L with Hg(ClO) also afforded a sandwich-type complex [Hg(L)](ClO) (5). One-pot reaction of L with a mixture of HgI and CdI afforded a dumbbell-type heteronuclear complex {[Cd(L)](μ-HgI)}[HgI] (6), in which the Cd(II) ion occupies the macrocyclic cavity. Further, such two endocyclic Cd(II) complex units are bridged by a square-type (μ-HgI) cluster remaining another same cluster separately. The comparative NMR data exhibited a higher affinity of Cd(II) over Hg(II) toward L, in the parallel to the situation occurred in the solid state. Meanwhile, complexations of the extra-large macrocycle L is more challenging to afford some interesting dimercury(II) coordination products including a cascade complex. In solution, the dimercury(II) perchlorato complex of L as a metalloligand shows a preferential binding of dabco (1,4-diazabicyclo[2,2,2]octane), but its dimercury(II) iodo complex has a much smaller affinity for dabco. In order to explain these results, the solid dimercury(II) complexes with different anions [Hg(L)X] (7: X = I, 8: X = ClO) were prepared and characterized. Further, the dimercury(II) perchlorato complex 8 reacts with dabco to forms a cascade complex [Hg(L)(μ-dabco)(ClO)](ClO)·2DMF·2ether (9), exhibiting its formation being metal-driven and coordinated anion-regulated. The observed cascade complexation both in solution and solid states is an example of the adaptive guest binding.

A series of 12 dinuclear complexes [Ln2Cl6(μ‐4,4′‐bipy)(py)6], Ln=Y, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, (1–12, respectively) was synthesized by an anhydrous solvothermal reaction in pyridine. The complexes contain a 4,4′‐bipyridine bridge and exhibit a coordination sphere closely related to luminescent lanthanide MOFs based on LnCl3 and 4,4‐bipyridine. The dinuclear complexes therefore function as a molecular model system to provide a better understanding of the luminescence mechanisms in the Ln‐N‐MOFs ${\hbox{}{{\hfill 2\atop \hfill \infty }}}$[Ln2Cl6(4,4′‐bipy)3]⋅2(4,4′‐bipy). Accordingly, the luminescence properties of the complexes with Ln=Y, Sm, Eu, Gd, Tb, Dy, (1, 4–8) were determined, showing an antenna effect through a ligand–metal energy transfer. The highest efficiency of luminescence is observed for the terbium‐based compound 7 displaying a high quantum yield (QY of 86 %). Excitation with UV light reveals typical emission colors of lanthanide‐dependent intra 4f–4f‐transition emissions in the visible range (TbIII: green, EuIII: red, SmIII: salmon red, DyIII: yellow). For the GdIII‐ and YIII‐containing compounds 6 and 1, blue emission based on triplet phosphorescence is observed. Furthermore, ligand‐to‐metal charge‐transfer (LMCT) states, based on the interaction of Cl− with EuIII, were observed for the EuIII compound 5 including energy‐transfer processes to the EuIII ion. Altogether, the model complexes give further insights into the luminescence of the related MOFs, for example, rationalization of Ln‐independent quantum yields in the related MOFs.
