Inorganic–Organic Hybrid Surfactant Crystals: Structural Aspects and Functions
نویسنده
چکیده
Hybrid single crystals consisting of an organic surfactant and an inorganic moiety are promising functional materials. Layered crystals composed from alternate inorganic and surfactant layers are obtained by the template effect of long alkyl chain moiety. The composition, crystal packing, and molecular arrangement of the hybrid single crystals are controllable by changing the inorganic constituent and the surfactant molecular structure. The types of hybrid surfactant single crystals are twofold: (i) crystals consisting of discrete inorganic cation coordinated by ligands having amphiphilic moiety; and (ii) crystals comprising a surfactant cation and a discrete inorganic anion including polyoxometalate (POM) oxide clusters. The POM-surfactant hybrid single crystals are rather rare, and therefore promising as unprecedented functional materials. Their structural variation and functional properties are discussed.

Controllable Layered Structures in Polyoxomolybdate-Surfactant Hybrid Crystals
Inorganic-organic hybrid crystals containing α-octamolybdate (Mo8) or hexamolybdate (Mo6) were isolated by using hexadecyltrimethylammonium (C16) surfactant. The packing mode of the inorganic layers depended on a difference in the polyoxomolybdate molecular structure. The structure for both crystals consisted of alternate stacking of C16 organic bilayers and polyoxomolybdate inorganic layers wi...

Inorganic-organic hybrid crystals were successfully obtained as single crystals by using polyoxotungstate anion and cationic dodecylpyridazinium (C12pda) and dodecylpyridinium (C12py) surfactants. The decatungstate (W10) anion was used as the inorganic component, and the crystal structures were compared. In the crystal comprising C12pda (C12pda-W10), the heterocyclic moiety directly interacted ...

A polyoxomolybdate inorganic-organic hybrid crystal was synthesized with deprotonatable ionic-liquid surfactant. 1-dodecylimidazolium cation was employed for its synthesis. The hybrid crystal contained δ-type octamolybdate (Mo₈) isomer, and possessed alternate stacking of Mo₈ monolayers and interdigitated surfactant bilayers. The crystal structure was compared with polyoxomolybdate hybrid cryst...
