Sažetak
Diamondoids are cage-like molecules that are highly stable and rigid, with a structure resembling the diamond crystal lattice. However, they have one significant advantage over diamond –diamondoids possess great capability for derivatization.1, 2 Diamondoids differ in size and higher homologues can exist as different isomers but the smallest diamondoid is adamantane. Due to their remarkable features, diamondoids and their derivatives can find uses in many fields such as medicine, 3 material science, 2 nanotechnology, 4, 5 supramolecular chemistry, etc.6, 7Recent investigation has shown that diamondoid derivatives can be applied in nanotechnology as scaffolds for formation of nanowires only one metal atom wide.4 These diamantane derivatives can be anchored to metal surfaces by on-surface reactions and are capable of holding single metal atoms in place at defined distances. The result is a precise spatial control and formation of nanowires, which has important implications for electronic device down-sizing.On the other hand, cationic diamondoid derivatives have the ability to form ultra-stable host-guest inclusion complexes, which have a potential as drug delivery vehicles.6, 7 For example, the permethylated diamantane diammonium salt binds to cucurbit[7]uril host with an attomolar dissociation constant, making it a non-covalent system capable of rivalling the very stable avidin-biotin affinity pair ubiquitous in nature.6 Design of such high-binding biomolecular receptors contributes to the development of synthetic systems whose functions meet and exceed their biological counterparts.7
