Patent ID: 7635762

Claim:
A metal ion coordinating component of a luminescent metal ion complex comprising: (i) a solid support covalently bonded to a non-nucleic acid spacer; (ii) a nucleobase covalently bonded to said non-nucleic acid spacer, wherein said nucleobase comprises a nitrogenous base; (iii) a linker covalently bonded to said nitrogenous base, wherein said linker has the formula: wherein, R 1 , R 2 , R 3 , and R 4 are individually selected from the group consisting of hydrogen, halogen, —OH, substituted or unsubstituted alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl, and OR 5 , wherein R 5 is selected from hydrogen and substituted or unsubstituted alkyl; Q 1 and Q 2 are individually selected from the group consisting of a bond, substituted or unsubstituted alkyl, and substituted or unsubstituted heteroalkyl; x and z are individually selected from the integers 0 to 100; and y is selected from the integers 1 to 100; (iv) a metal ion coordinating moiety covalently bonded to said linker to form said metal ion coordinating component.
