Abstract
The idea of this work is to utilise natural and synthetic porphyrins as photoredox catalysts in visible light 3D printing.
Chapter 1 provides a background of the use of light in organic synthesis, polymerisation and 3D printing.
Chapter 2 assessed the ability of both zinc tetraphenylporphyrin and tetraphenylporphyrin to photo catalyse the polymerisation of methyl acrylate in blue and red light, as well as the 3D print of a TEGDMA / UDMA solution in blue light.
Chapter 3 studied the effect of functionalising tetraphenylporphyrin with electron and donating groups and assessing the effect on photocatalytic ability in visible light 3D printing.
Chapter 4 looked at increasing the conjugation of the porphyrin core by utilising the heck reaction and studying the effect on absorption properties and photocatalyctivity for the polymerisation of methyl acrylate.
Chapter 5 analyses the use of chlorophyll a and pheophytin a from spinach and chlorella sources as a photocatalyst in the polymerisation of MA and 3D printing of a TEGDMA / UDMA solution. Also, the photocatalytic ability of crude extracts of chlorella and spinach was studied for the same purpose.
Chapter 6 is a summary of the work completed in this thesis.
Chapter 7 is the experimental procedures undertaken for this thesis.
Chapter 8 is a list of references used.
