The photodynamic activity of water insoluble porphyrins improved when encapsulated into the micelles. Novel asymmetrical phthalocyanines were also synthesised for nonlinear optics (NLO) studies in solution and thin films.]]> Wed 12 May 2021 16:05:57 SAST ]]> Evaluation of metallophthalocyanine functionalized photocatalytic asymmetric polymer membranes for pollution control and antimicrobial activity https://commons.ru.ac.za/vital/access/manager/Repository/vital:42052 Wed 12 May 2021 14:30:41 SAST ]]> Photocatalysis of 4-chloro and 4-nonylphenols using novel symmetric phthalocyanines and asymmetric porphyrin supported on polyacrylonitrite nanofibres https://commons.ru.ac.za/vital/access/manager/Repository/vital:41163 Wed 12 May 2021 13:49:36 SAST ]]> Dual and targeted photodynamic therapy ablation of bacterial and cancer cells using phthalocyanines and porphyrins in the presence of carbon-based nanomaterials https://commons.ru.ac.za/vital/access/manager/Repository/vital:65804 S0 excitation energies. The small deviation observed between the calculated and experimental spectra arises from the solvent effect. The excitation energies observed in these UV-Vis spectra mostly originated from electron promotion between the highest occupied molecular orbital (HOMO) for the less intense band and the HOMO-1 for the most intense band of the ground states to the lower unoccupied molecular orbital (LUMO) of the excited states.]]> Fri 17 May 2024 16:29:44 SAST ]]>
