Compositions and methods for single-step multipurpose surface functionalization

A compound of formula (I), or a salt or solvate thereof:

• wherein:
• L is a linker of formula *-X-(Y)ml-Z-, wherein * is the bond between X and the carbon marked as **, wherein:
• X is a bond (null), —C(═O)—, —C(═O)NH—, —C(═O)N(C6—10 aryl)—, —C(═O)N(C2—10 alkenyl)—, or —C(═O)N(C1—10 alkyl)—, wherein the C6-10 aryl is optionally substituted by at least one substituent independently selected from the group consisting of halogen, —R′, —OR′, and —C(═O)OR′;
• each occurrence of Y is independently selected from the group consisting of —CHZCH2O—, —OCH2CH2—, and —CH2CH2—, wherein each CH2 is independently optionally substituted with 1 or 2 CH3 groups;
• Z is —(CH2)m2—, wherein each CH2 is optionally independently substituted with 1 or 2 CH3 groups;
• each occurrence of R′ is independently hydrogen, C2-5 alkenyl, or C1-5 alkyl;
• m1 is 0, 1,2,3,4, 5, 6, 7, 8, 9, or 10;
• m2 is 0, 1, 2, 3, 4, or 5;
• with the proviso that L is not —C(═O)NHCH2—.
