We report the synthesis of two isomeric Pt(II) complexes ligated by doubly deprotonated 1,1′-bis(<i>o</i>-carborane) (<b>bc</b>). This work provides a potential route to fine-tune the electronic properties of luminescent metal complexes by virtue of vertex-differentiated coordination chemistry of carborane-based ligands.

Macrocyclic Cavity

The protonation constants of two series of tetraazamacrocyclic ligands with acetate and methylphosphonate pendant arms, as well as their stability constants with Cu2+, La3+, Sm3+, and Ho3+, were determined. All the values were determined in aqueous solution at 298.0 K and 0.10 mol dm–3 in N(CH3)4NO3. In the first series, the effect of both types of pendant arms was observed by appending them in the same macrocyclic backbone, a 14-membered tetraazamacrocycle containing pyridine (ac3py14, p2py14, and p3py14). In the second series, two effects were taken into account, the increase of the cavity size of the macrocycle, from 12- to 14-membered, and the appending of acetate (dota, trita, and teta) or methylphosphonate (dotp, tritp, and tetp) arms. The ligands containing methylphosphonate arms have higher thermodynamic stability compared to the corresponding ones with acetate arms, especially in the series of compounds containing pyridine, even upon correction of the different basicity values of the ligands. On the other hand, the ligands with smaller macrocyclic cavity size, namely, dota and dotp, exhibit the largest values of stability constants. In contrast, ac3py14 presents low stability constants with lanthanides. An interpretation of these features based on the known adopted arrangement of dota and teta when free or coordinated with lanthanides is evaluated.

A review is given of the latest contribution of the author’s research group to the coordination chemistry of Schiff base polyaza macrocycles and acyclic salicylaldimines. Focus is placed on the effectiveness of lanthanides in supramolecular self-assembly of the components leading to the formation of compounds with unusual properties and structures.Key words: Schiff base macrocycles, salicylaldimines, lanthanides, self-assembly, template synthesis.
