Investigation of Light-harvest Material:Synthesis and Characterization of Nanometer Porphyrin Trimer

ω-Bromopropylporphyrin ether synthesized from the raction of 1,3-dibromopropane as the bridge-linked reagent and 5-(4-hydroxyphenyl)-10,15,20-triphenylporphyrin (H2MHTPP) as the matrix reacts with 5, 15-di(4- hydroxyphenyl)-10, 20-diphenyl porphyrin(trans-H2DHDPP) to give the title nanometer porphyrin trimer. The characterization was carried out by means of elemental analyses, UV-Vis, IR, 1H NMR and XRD.
