What is claimed is: 1. A compound having the following structure (IA): or a stereoisomer, pharmaceutically acceptable salt or tautomer thereof, wherein: M is, at each occurrence, independently a biologically active moiety selected from an non-steroidal anti-inflammatory drug (NSAID), a kinase inhibitor, an anthracycline, an epidermal growth factor receptor (EGFR) inhibitor, an alkylating agent, and an anti-cancer drug, or a fluorescent dye, provided at least one occurrence of M is not a fluorescent dye; L 1 and L 2 are, at each occurrence, independently an alkylene, heteroalkylene, or heteroatomic linker, wherein the heteroatomic linker is one or more heteroatoms; L 4 is, at each occurrence, independently an alkylene or heteroalkylene, or absent; L 5 is, at each occurrence, independently an alkylene or absent; L 6 is, at each occurrence, independently a linker comprising an amide bond, an ester bond, a disulfide bond, a double bond, a triple bond, an ether bond, a ketone, a diol, a cyano, a nitro or combinations thereof; L 7 and L 8 are, at each occurrence, independently an alkylene, alkenylene, alkynylene, heteroalkylene, heteroalkenylene or heteroalkynylene linker; R 1 is, at each occurrence, independently H, alkyl or alkoxy; R 2 is —OP(═R a )(R b )R c ; R 3 is, at each occurrence, independently OH, —OP(═R a )(R b )R c , Q or has the following structure: R a is O or S; R b is OH, SH, O − , S − , OR d or SR d ; R c is OH, SH, O − , S − , OR d , OL′, SR d , alkyl, alkoxy, heteroalkyl, heteroalkoxy, alkylether, alkoxyalkylether, phosphate, thiophosphate, phosphoalkyl, thiophosphoalkyl, phosphoalkylether or thiophosphoalkylether; R d is a counter ion; R 4 is, at each occurrence, independently OH, SH, O − , S − , OR d or SR d ; R 5 is, at each occurrence, independently oxo, thioxo or absent; Q is, at each occurrence, independently a moiety having one of the following structures: wherein: each X is independently a halogen; and EWG is an electron withdrawing group; L′ is, at each occurrence, independently a linker comprising a covalent bond to Q, a targeting moiety, a linker comprising a covalent bond to a targeting moiety, a linker comprising a covalent bond to a solid support, a linker comprising a covalent bond to a solid support residue, a linker comprising a covalent bond to a nucleoside or a linker comprising a covalent bond to a further compound of structure (IA), wherein the targeting moiety is an antibody or cell surface receptor antagonist; L 2 ′ is, at each occurrence, independently a direct bond, an optional alkylene, alkenylene, alkynylene, heteroalkylene, heteroalkenylene, heteroalkynylene or heteroatomic linker; L 3 is, at each occurrence, independently an alkylene, alkenylene, alkynylene, heteroalkylene, heteroalkenylene, heteroalkynylene linker, or absent; n is, at each occurrence, independently an integer of one or greater; m is, at each occurrence, independently an integer of one or greater; p is, at each occurrence, independently an integer of one to ten; and q is, at each occurrence, independently an integer of zero or greater; wherein R 2 or at least one of occurrence of R 3 has the following structure: 2. The compound of claim 1 , wherein at least one occurrence of R 3 has the following structure: wherein: L 2 ′ is a direct bond. 3. The compound of claim 1 , wherein L 3 is a heteroalkylene linker. 4. The compound of claim 1 , wherein m is, at each occurrence, independently an integer from 1 to 25. 5. The compound of claim 1 , wherein n is, at each occurrence, independently an integer from 1 to 10. 6. The compound of claim 1 , wherein R 3 is each independently OH or —OP(═R a )(R b )R c . 7. The compound of claim 1 , wherein R 3 is Q. 8. The compound of claim 1 , wherein R 3 is each independently —OP(═R a )(R b )R c . 9. The compound of claim 8 , wherein R c is OL′. 10. The compound of claim 9 , wherein L′ is a targeting moiety or a linker to a targeting moiety. 11. The compound of claim 1 , wherein R 2 or R 3 has one of the following structures: 12. The compound of claim 1 , wherein M is, at each occurrence, independently an anti-cancer drug, and the targeting moiety is an antibody specific for a tumor cell antigen. 13. The compound of claim 1 , wherein the compound has one of the following structures: wherein N′ or I′ is M, wherein N′ has the following structure: wherein I′ has the following structure: wherein dT is a deoxythymidine (dT) group and has the following structure: wherein: R is H. 14.
