Abstract
Disclosed herein are coated gemstones, coatings for gemstones, methods of coating gemstones, and methods of using coatings on gemstones to avoid blemishes on gemstones. In some embodiments, diamonds are functionalized with anchor molecules that bind hydrophilic cyclodextrin molecules to confer hydrophilicity on the diamond. In some embodiments, the diamonds resist dirt and grime build-up.
Claims19
A coated gemstone comprising a coating and a gemstone, the coated gemstone represented by Formula I:
- where
- G represents the gemstone and the coating comprises -A(-X)m;
- A is an anchor moiety covalently bonded to G;
- X is a guest moiety covalently bonded to A;
- m is an integer between 1 and 5;
- and
- wherein the coated gemstone is configured to resist the accumulation of oil and dirt on the surface of the gemstone when functionalized with the host,
- wherein the gemstone is a diamond and -A(-X)m is represented by the following structure:
- where indicates a bond to G.
A coated, soil-resistant gemstone comprising an anchor irreversibly linked to the gemstone and a binding agent, wherein the anchor comprises a pendant binding portion that reversibly binds to the binding agent,
- wherein the binding agent is hydrophilic.
A coated gemstone comprising a coating and a gemstone, the coated gemstone represented by Formula I:
- where
- G represents the gemstone and the coating comprises -A(-X)m;
- A is an anchor moiety covalently bonded to G;
- X is a guest moiety covalently bonded to A;
- m is an integer between 1 and 5;
- and
- wherein the coated gemstone is configured to resist the accumulation of oil and dirt on the surface of the gemstone when functionalized with the host,
- wherein, A is represented by Formula AIII:
- wherein indicates a bond to G;
- R5, R6, R7, R8, R9, R10, R11, and R12 are independently selected from —H, C1 to C6 alkyl optionally substituted with halogen or hydroxy, C1 to C6 alkenyl optionally substituted with halogen or hydroxy, C1 to C6 alkynyl optionally substituted with halogen or hydroxy, C1 to C6 alkoxy, hydroxyl, halogen, C1 to C6 haloalkyl, C1 to C6 haloalkoxy, a mono-substituted amine(C1 to C6 alkyl), a di-substituted amine(C1 to C6 alkyl), a diamino-group, a polyamino, a diether-group, and a polyether;
- and
- X is a guest moiety represented the following structure:
- where * represents a bond to A;
- and
- t is an integer from 0 to 5.
