Inorganic–Organic Hybrid Surfactant Crystals: Structural Aspects and Functions

“…Metal halide infinite layers and chalcogenide molecular clusters comprise heavier and more polarizable atoms (S, Cl, Se, Br, and I), and exhibit characteristic electronic property owing to their polymeric structures such as semiconductivity [13,16,[82][83][84][85][91][92][93][94] or photoluminescence [13,16,85,90]. Surfactant hybrid crystals composed from these metal halide and chalcogenide polymeric anions can be applicable to dye-sensitized solar cells [95,96] and electronic devices [97].…”

“…These inorganic monolayers The polymeric anions realize more integrated metal ions confined in the two-dimensional inorganic layer, and are expected to emerge specific electronic properties [10][11][12][13][14]16]. The metal halides tend to form a perovskite-type infinite two-dimensional layered structure [13], which consists of a polymeric metal halide layer such as [PbI 4 ] 2´( Figure 5) Figure 5), and are hybridized to form layered single crystals [81][82][83][84][85]. Such molecular cluster-surfactant hybrid single crystals are much more unconventional materials.…”

Noncovalent supramolecular assembly of hexagonally ordered mesoscale Prussian blue analogue

“…No X-ray reflections from the mesostructure in a low angle region were observed. In fact, the significant role of different bridging metal ions for the formation of highly ordered mesostructures has often been observed [15][16][17]. We speculate that subtle variation of the coordination environments of different metal ions with [Fe(CN) 6 ] 3À ion greatly affects the structural orderliness of the final mesostructures.…”

“…Since then this approach has been used to prepare a wide range of mesoporous oxides [3][4][5][6]. This route has been further extended to the synthesis of nonoxidic mesostructured materials based on the assembly of tetrahedral building blocks such as metal chalcogenide complexes [7][8][9][10][11][12][13][14] and octahedral hexarhenium chalcogenide cluster anions [15][16][17] with various linking transition metal cations. More importantly, MacLachlan et al used alkyl pyrazinium surfactants which can coordinate to mononuclear octahedral complex anion [Fe(CN) 5 NH 3 ] 3À to make a kinetically stable micellar assembly in the presence of various linking metal ions including Fe 3+ , Cu 1+/2+ , Mn 2+ , Ni 2+ , Zn 2+ , Gd 3+ , and Er 3+ [18].…”

[Re6(μ3-Se)8]2+ Core-Containing Cluster Complexes with Isonicotinic Acid: Synthesis, Structural Characterization, and Hydrogen-Bonded Assemblies

“…Several of these compounds utilize [Re 6 (l 3 -Se) 8 (CN) 6 ] 4-as a linker to build polymeric arrays with direct coordination to secondary metal ions [15][16][17][18][19][20][21][22][23]. Other efforts involve incorporating cluster systems into polymers [24], nanoparticles [25], self-assembly structures [26][27][28], and surfaces [29], all for the purpose of integrating the red/nearinfrared luminescence and redox properties of the cluster for functional materials. Multi-cluster supramolecular assemblies have also been constructed by using cluster complexes with ligands capable of hydrogen bonding as building blocks [30][31][32][33], and ligands such as isonicotinamide and 3,5-pyridinedicarboxylic acid have been used in such studies [34][35][36].…”
