Figure 3. Schematic representation of two different hexagonal arrangements in mesostructured inorganic / surfactant composites the hydrophobic chains are drawn as straight lines for simplicity, (a) The normal structure with a fully-connected inorganic network (dark area), (b) Inverse surfactant assemblies with single domains of the inorganic material enclosed in the centres. In the latter case the hydrophobic surfactant chains are allowed more space for their distribution, leading to a smaller d spacing. In this picture they are also interpenetrating each other.

A rack-like arrangement schematically represented by 160, would be formed by the complexation of several metal ions to rigid, linear sequences of binding sites. Thus, binding of bipy or phen units to 155 and to its extended tri- and tetratopic analogues present in 157 and in 158 via metal ions of tetrahedral coordination such as Cu(l) and Ag(l) should yield rack structures of type 160. With the bipy or phen unit included in a macrocycle, inorganic rotaxane-type structures (see also Section 9.6) such as 159 have been obtained [9.97a]. A linear sequence of connected terpy sites such as 161 yields racks with individual terpy units and metal ions of octahedral coordination [9.97b].

Up to now, only two one-dimensional zirconium phosphates have been reported. One is [enH2][Zr(HP04)3] [16], and the other is zirconium phosphate fluoride [enH2]i.5[Zr(P04)(HP04)F2] [13] with double-stranded chains. The simple models of one-dimensional chain inorganic polymers are shown schematically in Figure 2. ZrPO-3 has a chain- structure similar to the one-dimensional aluminum phosphate, [A1P208H]2 [29].

As a result of these factors, the universal paradigm for inorganic solar cells, the p-n junction, cannot be adapted for organic semiconductors. The contrast with inorganic semiconductors is shown schematically in Fig. 7.2. The alternative of a metal-semi-conductor-metal device structure, where photocurrent is directed by the difference in work function between the two metals, also cannot be used because the electric field created by available asymmetric contact materials is insufficient to separate the singlet exciton into electron and hole polarons. Therefore, alternative device architectures are needed.
