“…[5,6] In this regard, Kunz et al have shown that the intercalation of [Ru(bpy) 3 ] 2+ (bpy = 2,2'-bipyridine) into as ynthetic clay mineral leads to the polarized emission of light. [8] Forexample,intercalation of the fluorescent stilbazolium dye N-hexadecyl-4-(3,4,5-trimethoxystyryl)-pyridinium (subsequently shortened to dye) into well-characterized Na-hec [9] at alevel whereby 38 %ofthe pristine interlayer cation (Na + ) is exchanged by dye leads to aperfectly ordered interstratified heterostructure [8] with strictly alternating layers of hydrated Na + and dye.T he formation of the heterostructures is based on the partition equilibrium between the intercalated dye and the dye in solution. [8] Surprisingly, we now succeeded in spontaneously delaminating this material into double stacks of two highly transparent, flexible silicate layers that encapsulate ac entral organic layer of oriented functional molecules.M oreover,t he large aspect ratio of these delaminated double stacks inevitably leads to perfectly textured films upon casting suspensions on flat substrates,which in turn results in apseudoepitaxial orientation of the encapsulated functional moiety.…”
