Energy transfer proceeds in orthogonal dyads in contrast to Förster’s theory and cannot be prohibited even by rigid interconnecting cage compounds such as cubane or diamantane.

Be our guest! Carboxy- and amino-substituted molecular nanodiamonds (adamantane, diamantane, and triamantane) are excellent guest molecules for β- and γ-cyclodextrin due to their hydrophobicity and symmetry. Additionally, these high-affinity guest molecules are used as non-covalent anchor molecules for the selective self-assembly of cyclodextrin vesicles (see scheme; ConA=concanavalin A).
adamantane- and diamantane-based guests containing one ammonium group formed stable 1 : 1 complexes with β-CD, whereas only the diamantane derivative interacted with γ-CD. The thermodynamics of the binding processes was characterized in detail by means of ITC and the origin of the enthalpic and entropic contributions was discussed. Structural features of the complexes were deduced from the data gathered
We report the synthesis of diamondoid nitro derivatives via the selective oxidation of the corresponding amines using m-chloroperbenzoic acid in 1,2-dichloroethane as solvent.
The amino derivatives of diamantane and triamantane, representing close topological analogues of the neuroprotective drug Memantine®, were prepared via amination of the respective carboxylic acids or alcohols. amines - diols - drugs - hydrocarbons - medicinal chemistry
