A zinc-based metal organic framework and method of making is described. The zinc-based metal organic framework is in the form of an interpenetrating diamondoid framework where each Zn.sup.2+ ion center is linked with four other Zn.sup.2+ ion centers in a distorted tetrahedral geometry. The linking occurs through diamine and dicarboxylic acid linkers. The zinc-based metal organic framework may be deposited on a transparent conducting film and used as a photoelectrode for photoelectrochemical water splitting.

The present invention relates to a one-step process for preparation of “in-situ” or “ex-situ” self-organized and electrically conducting polymer nanocomposites using thermally initiated polymerization of a halogenated 3,4-ethylenedioxythiophene monomer or its derivatives. This approach does not require additional polymerization initiators or catalysts, produce gaseous products that are naturally removed without affecting the polymer matrix, and do not leave by-product contaminants. It is demonstrated that self-polymerization of halogenated 3,4-ethylenedioxythiophene monomer is not affected by the presence of a solid-state phase in the form of nanoparticles and results in formation of 3,4-polyethylenedioxythiophene (PEDOT) nanocomposites.
