摘要	Star poly(lactic acid) was successfully synthesized via bulk ring opening polymerization of lactide using meso-tetra(p-aminophenyl) porphyrin (TAPP) as initiator and stannous octanoate (Sn(Oct)(2)) as catalyst under vacuum. Molecular structure of the four armed poly (lactic acid) was characterized via H-1-NMR and FTIR. It was confirmed that the star poly(lactic acid) was comprised with four-armed polymer chain and a tin porphyrin core. The molecular weight was also studied via GPC and H-1-NMR, and molecular weight distribution was also characterized (M-w/M-n = 1.97). Both star poly (lactic acid) film and linear poly (lactic acid) film were prepared using solution-casting method. Structural analysis via X-ray diffraction indicates that the star poly(lactic acid) films display the orthorhombic alpha-crystalline form, while linear poly(lactic acid) films display amorphous structure. The photoelectron study of the functional poly(lactic acid) via UV-Vis absorption spectra reveals that the star poly(lactic acid) displays photoelectric property of tin porphyrin.
