Enediyne units can also be substructures in molecules de- signed to serve as precursors to two-dimensional carbon networks.3 Very often, substances of this type are made up of tetraethynylethene building blocks.4 Carbon networks prepared from this type of molecules would have distinc- tive physical properties; selective substitution of the mo- nomeric starting materials with cyclic aliphatic or aromat- ic saturated or polyunsaturated groups could probably sig- nificantly ...
