Abstract

The enormous potential of parallel computing has led to the first prototype devices being constructed. However, all the examples to date rely on complicated chemical and/or physical manipulations, and hence do not lend themselves to the kind of widespread investigation necessary to advance the field. This article presents a new paradigm for parallel computing: the use of solid, single crystalline materials as cellular automata suggesting the idea of the “Crystal Computer,” now possible due to a new class of crystalline cellular materials that undergo single-crystal-to-single-crystal (SC-SC) oxidation and reduction (REDOX) reactions. Two avenues are proposed for investigation: reversible single-crystal to single-crystal electronic transformations and solid-state spin transfer within spin-crossover complexes. Both schemes allow computation to occur in three dimensions, within cheap and easy to assemble materials and using commonplace techniques for input and readout.

Crystal Computing With Polyoxometalates

Crystals of the form [(C4H10NO)40(W72M12O268Si7)]·48H2O (M = MnIII) (1ox) self-assemble from a solution of the well-studied tungsten polyoxometalate [γ-SiW10O36]8- and a simple manganese(II) salt and hence are straightforward to prepare. The structure of these crystals comprises an infinite array of 3- and 4-connected Keggin polyanions (Long et al., 2010), where each three connected unit is surrounded by three neighboring clusters in a trigonal-planar fashion, and each 4-connected unit features four nearest neighbors located on the vertices of a distorted tetrahedron (Figure 1).
