Poly (ethylene oxide) tethered trans-porphyrin: Synthesis, self-assembly with fullerene (C60) and DNA binding studies

We report here, the synthesis and morphological investigation of ABA type PEGylated trans-porphyrin, P-(PEO)2. These porphyrinic moieties self-assembled into spheres of uniform diameter when their DMF solution was dialyzed into water. Furthermore, the addition of C60 to P-(PEO)2 caused morphological change of worm like lateral aggregates. The aggregates were further studied for DNA attachment using change in their electrochemical properties.266
