Abstract:
Extending quantum effects beyond the nanoscale has been a long-standing goal of chemists and physicists. Graphene has provided one very successful avenue, and porphyrin nanostructures have been another. To date, large porphyrin nanostructures have only been realized as onedimensional tapes or rings. In Nat. Commun. 2023, 14, 6308, we described the synthesis of sheets of porphene 1, a 2-D material made of porphyrin macrocycles. If DFT predictions of metalloporphene properties are right, if our ability to reversibly insert metal ions into porphene can be perfected, if we can produce patterns lithographically or by ink printing, and if we can make and stack distinct single crystalline metalloporphene monolayer domains of sufficient size with sufficiently accurate registry, it will be possible to construct flexible monolithic electronic, photonic, and spintronic circuitry analogous to that currently available in silicon with an ultimate resolution of 0.84 nm.
