1. A sensor for detecting an analyte comprising a polymer, wherein said polymer comprises one or more residues of a luminescent dye, and wherein the luminescent dye is a photostable porphyrin dye and has excitation and emission spectra in the NIR optical window of a mammalian skin
wherein the luminescent dye is a compound having formula:wherein M is H, Pd, Zn, Pt, Gd or Yb;
each R1 is same or different and, independently, C(O)X—(CH2)n—YC(O)C(R4)CH2 or C(O)X—(CH2CH2O)mCH2CH2—YC(O)C(R4)CH2; R2 is C(O)X—(CH2)n—YC(O)C(R4)CH2, C(O)X—(CH2CH2O)mCH2CH2—YC(O)C(R4)CH2; R2 and R3 are fused, in each case, to form a cycloalkenyl, aryl, or heteroaryl group; X is O or NR5; Y is O; R5 and R4 are independently H or C1-C4 alkyl; each R6 is same or different and, independently, H or F; n is 1-10; and m is 1-300. |
