Self-assembled coordination complexes from various palladium(II) components and bidentate or polydentate ligands

Anticancer Potencies of PtII‐ and PdII‐linked M2L4 Coordination Capsules with Improved Selectivity

“…[13] In contrast to commonM 2 L 4 cages with large openings, [14] the capsules provide as pherical cavity fully surrounded by multiple anthracene panels. The isolated cavity, with ad iameter of~1nma nd av olume of~600 3 ,c an accommodate variouso rganic molecules (e.g.,c yclophane, pyrene, and triphenylene) through mainly hydrophobic effects.…”

Polycationic‐Shelled Capsular and Tubular Nanostructures and Their Anionic–Guest Binding Properties

“…e) Electrostatic potential maps (front view)o fd icationic bisacridinium ligand 1 (left) and neutral bisanthracene ligand 1' (right). [1,15] In addition, we for the first time demonstratedt he high utility of the acridinium ring, which is aw ell-known and readily accessiblec ompound, [6] for the preparation of various polycationic-shelled nanoarchitectures. [10] As compared with neutral bisantharcenel igand 1', [7d] the new ligand shows higher solubility (> 4mm)i nw ater despite the lack of pendanth ydrophilic groups.…”

“…[12,13] The structure of 2 is quite similart ot hat of 2' except for the exteriorf unctional groups. [1,15] In addition, we for the first time demonstratedt he high utility of the acridinium ring, which is aw ell-known and readily accessiblec ompound, [6] for the preparation of various polycationic-shelled nanoarchitectures. In the crystal structure, two molecules of 1 are connected by two square-planar Pd II ions in a trans fashion to generateatubular structure with four acridiniumr ings (Figure 3b).…”

[14] Thanks to the facile synthesis of non-substituted M 2 L 4 capsule 2 (three steps from simple dibromoarene), the anisotropic expansion of the spherical capsule was accomplished by using an elongated bisacridinium ligand (4;F igure 3d).…”

Structural Diversity of Metallosupramolecular Assemblies Based on the Bent Bridging Ligand 4,4′-Dithiodipyridine

“…Metallosupramolecular chemistry also offers the promise of novel materials with interesting properties. Discrete metallosupramolecular assemblies, e.g., metallamacrocycles, box and cage compounds, have been used, for example, as receptors and reaction containers [5][6][7][8][9][10]. Potential applications in catalysis, gas-storage, separation, sensing, magnetism, optics and electrochemistry have often been mentioned in connection with coordination polymers [11][12][13][14][15][16][17].…”
