Objectives
General NotesThe propyhrin film crosslinked last time lost all color. Appears as if not porphyrin remains on the film. Need to use UV-vis to confirm Film preparationAll films followed the general protocol of glutaraldehye and porphyrine film preparation. Films containing additional HCl had two drops of HCl added to the reaction mixture and were allowed to stir until the reaction mixture was a uniform green color. HCl was added after both glutaraldehyde and porphyrine
