Photophysical Property Investigation of Nanometer Porphyrin Oligomer

Abstract:

In this paper, ω-bromopropylporphyrin ether was firstly synthesized using 1,3-dibromopropane as bridge-linked group and 5-(4-hydroxyphenyl)-10,15,20-triphenylporphyrin (H₂MHTPP) as the matrix. The resulting compound was then reacted with 5,15-di(4- hydroxyphenyl)-10,20-diphenyl porphyrin (trans-H2DHDPP) to give a new title nanometer porphyrin oligomer. Characterization were made by the methods of elemental analysis, UV-vis, IR, ¹H NMR and XRD. Has studied the crystalline ,the fluorescence property and the heat-stable property of porphyrin monomer and porphyrin oligomer. The research discovered that the crystalline,the fluorescence property and the heat-stable property can have the very big change along with the porphyrin peripheral substitution groups as well as the oligomer formation. And the function of difference kinds of solvent and the porphyrin molecular structure symmetry also can have the very tremendous influence to the crystalline,the fluorescence property and the heat-stable property.
