Porphyrinated poly(-stearyl L-glutamate)s(PSLGs) were synthesized by the ringopening polymerization of -stearyl L-glutamate N-carboxyanhdyride(SLGNCA) with 5-(4-aminophenyl)-10

15

20-triphenylporphyrin (APTPP) and corresponding zinc and cobalt porphyrins(ZnAPTPP

CoAPTPP) as initiators.Intrinsic viscosity measurement shows that the PSLGs initiated by CoAPTPP have much higher molecular weight than that by APTPP and ZnAPTPP.UV-Vis and fluorescence spectra of the porphyrinated PSLGs exhibited typical absorptions and emissions

which are consistent with those of the corresponding porphyrin initiators.These porphyrinated PSLGs were electrospun into microfibers from chloroform solutions.Well-defined microfibers

however

were obtained only from PSLG with high intrinsic viscosity that was prepared by CoAPTPP.The fabricated porphyrinated PSLG electrospun mats emitted red fluorescence uniformly regardless of their microstructures

whereas the intensities varied with the porphyrin attached in the polymer.The fluorescence intensities of PSLG mats containing APTPP and ZnAPTPP were very strong while that of PSLG mats containing CoAPTPP were very weak due to the fluorescence quenching of cobalt porphyrin.In combination of the unique optical property of porphyrin with biocompatibility of PSLG

the porphyrinated PSLGs and electrospun mats are potential for the applications in sensory material and drug delivery system.
