摘要

L is a linker selected from a group featuring —(CH2)s—, —[(CH2)m—O]p—(CH2)m—, —NR10-(CH2)s—, —O—(CH2)s—, —S—(CH2)s—, —NR10-C(O)—(CH2)s—, —NR10-C(O)—O—(CH2)s—, —NR10-C(O)—NR11-(CH2)s— or —SO2—NR10-(CH2)s—, wherein R10 and R11 are each independently hydrogen, alkyl and alkoxy-alkyl (—[(CH2)m—O]p—CH3), ω-sulfoalkyl (—(CH2)r—SO3), m represents the numbers of 2-5, p, r and s each independently represent the number of 1-10.
