  We propose a new environment for information encoding and transmission via a
novel type of molecular Quantum Dot Cellular Automata (QCA) wire, composed of a
single row of head-to-tail interacting 2-dots molecular switches. While most of
the research in the field refers to dots-bearing molecules bound on some type
of surface, forming a bidimensional array of square cells capable of performing
QCA typical functions, we propose here to embed the information bearing
elements within the channels of a microporous matrix. In this way molecules
would self-assemble in a row as a consequence of adsorption inside the pores of
the material, forming an encased wire, with the crystalline environment giving
stability and protection to the structure. DFT calculations on a diferrocenyl
carborane, previously proposed and synthesized in the literature, were
performed both in vacuum and inside the channels of zeolite ITQ-51, indicating
that information encoding and trasmission is possible within the nanoconfined
environment.
