Metal Influence in Porphyrine Structure on Kinetic of Electrodeposition and Morphology of Hydroxyphenylporphyrins Based Films

“…In order to degas or oxygenate solutions before the electrochemical measurements, argon or oxygen was bubbled through the capillary tube for 30 min. In earlier paper we have shown that in DMSO media the more effective electrochemical deposition of polyporphyrin films was obtained under activation by oxygen [31,32]. Therefore, in this paper the polyporphyrin films deposition included cycling of the working electrode potential in the oxygenated solutions (to activate the deposition process), then cycling in degassed solutions (to stabilize the resulting film).…”

In Situ Catalytic Reaction for Solving the Aggregation of Hydrophobic Photosensitizers in Tumor

“…4−8 The aggregation of photosensitizers could enhance the transfer of electrons produced by photosensitizers under illumination and further increase the production of superoxide anions (O 2 − ). 9,10 The O 2 − has low or less toxicity to tumor cells because it could be eliminated by superoxide dismutase (SOD). 11−15 Meanwhile, the aggregation of photosensitizers could also increase nonradiative transitions of photosensitizers (relaxation vibration, internal transitions, and intersystem transitions), and their absorbed light energy is released in the form of heat.…”
