Study On Preparation And Performance Of Nonlinear Optical Polymers Matarial Containing Porphyin

Porphyrin compounds are a macrocyclic conjugated compounds which have special structure and unique properties.It have a very wide range of uses in photochemistry, medicine, materials chemistry, biochemistry, energy and other areas.so more and more Research Scholars pay attention and concern on these compounds.In this thesis, firstly, we used the classical synthesis method of porphyrin (The acid method) to synthesize a series of hydroxyethoxy phenyl porphyrins.used the acetate method to synthesize the corresponding metal hydroxyethoxy phenyl porphyrin complexes. Secondly, we used the 2-Bromo-2-methyipropionyl bromide to replace the end bit H of Hydroxyethoxy phenyl porphyrin to get the metal porphyrin initiator which can initiate atom transfer radical polymerization. Finally, used the atom transfer radical polymerization method to complete with the preparation of optical nonlinearities porphyrin polymer materials.We determined the structures of ATRP polymer and series of Hydroxyethoxy phenyl porphyrin by Infrared absorption spectrometer, UV-visible spectroscopy and nuclear magnetic resonance. We tested and analysised this new type of polymer molecular weight, molecular weight distribution and the optical limiting performance by using GPC, Z-scan and other tests. The results show that this new type of metal porphyrin polymers as nonlinear optical materials in optical limiting field has a good prospect.
