Transitionary materials

All materials in the "ladder" of technology levels
that lie above nature/bioderived foldamers like:

• Structural DNA nanotechnology
• De-novo protein engineering

and below gemstones materials that can only be
piezomechanosynthesized in PPV like diamondoid crystolecules.

Examples

Organics beyond foldamers:

• Highly polycyclic small molecules

Metalorganics:

• Metal organic frameworks

Minearals that like to behave like atomically precise molecules. Kinda like natural crystolecules:

• Polyoxymetalates

In water (abiotic) mechanosynthesizable gemstones including biominerals and other minerals:

• ceria – as it has good lattice scaled stiffness
• Sulfides and oxides: pyrite, periclase
• Iron oxides: magnetite, magnesite
• Oxoacid salts of calcium: apatite (phosphate), calcite & aragonite (carbonates), gypsum (soft sulfate),
• Some Mohs scale defining aluminosilicate oxidic minerals: 6 orthoclase, 7 quartz, 8 topaz, 9 sapphire
• More complex minerals with nice cubic structure: spinels, garnets, perovskites, ...

In non-aquaeous solution mechanosynthesizable gemstones:

• ... ???
