The incorporation of the MWCNTs on the surface of the TiO2 film (MOCPc–MWCNT systems) gave higher photocurrent density than the bare MOCPc complexes. Also, from the EIS results, the MOCPc–MWCNT hybrids gave faster charge transport kinetics (approximately three times faster) compared to the bare MOCPc complexes. The electron lifetime was slightly longer (ca. 6 ms) at the ZnOCPc systems than at the (OH)2SiOCPc system (ca. 4 ms) meaning that the presence of the MWCNTs on the surface of the TiO2 film did not show any significant improvement on preventing charge recombination process.]]> Wed 12 May 2021 16:21:16 SAST ]]> Facile synthesis, spectroscopic and electrochemical properties, and theoretical calculations of porphyrin dimers with a bridging amide-bonded xanthene moiety https://commons.ufh.ac.za/vital/access/manager/Repository/vital:7292 Wed 12 May 2021 16:09:03 SAST ]]> Organosilicon compounds as fluorescent chemosensors for fluoride anion recognition https://commons.ufh.ac.za/vital/access/manager/Repository/vital:50938 Wed 11 May 2022 21:15:05 SAST ]]> Facile synthesis, spectroscopic and electrochemical properties, and theoretical calculations of porphyrin dimers with a bridging amide-bonded xanthene moiety https://commons.ufh.ac.za/vital/access/manager/Repository/vital:50935 Wed 11 May 2022 20:47:34 SAST ]]> Effect of peripheral fused ring substitution on the optical spectroscopy and electronic structure of metal phthalocyanine complexes https://commons.ufh.ac.za/vital/access/manager/Repository/vital:53620 Wed 10 Apr 2024 15:21:21 SAST ]]> Physicochemical and photodynamic antimicrobial chemotherapy activity of morpholine-substituted phthalocyanines: Effect of point of substitution and central metal https://commons.ufh.ac.za/vital/access/manager/Repository/vital:44652 Wed 06 Oct 2021 09:23:57 SAST ]]> Optical limiting properties of 2, 6-dibromo-3, 5-distyrylBODIPY dyes at 532 nm https://commons.ufh.ac.za/vital/access/manager/Repository/vital:44991 Wed 03 Nov 2021 10:58:48 SAST ]]> Electrocatalytic behavior of cobalt phthalocyanine complexes immobilized on glassy carbon electrode towards the reduction of dicrotophos pesticide https://commons.ufh.ac.za/vital/access/manager/Repository/vital:51409 Tue 24 May 2022 23:11:37 SAST ]]> Flexible Metal–Porphyrin Dimers (M= MnIIICl, CoII, NiII, CuII) https://commons.ufh.ac.za/vital/access/manager/Repository/vital:50754 Tue 24 May 2022 15:19:37 SAST ]]> Optically active BODIPYs https://commons.ufh.ac.za/vital/access/manager/Repository/vital:50833 Tue 24 May 2022 14:46:06 SAST ]]> Synthesis and Photophysical Investigation of Tetraazaporphyrin Substituted with Aggregation‐Induced Emission (AIE) Active Moieties https://commons.ufh.ac.za/vital/access/manager/Repository/vital:45346 Tue 23 Nov 2021 11:56:07 SAST ]]> Synthesis and photophysical studies of asymmetric zinc phthalocyanine–magnetic nanoparticle conjugates https://commons.ufh.ac.za/vital/access/manager/Repository/vital:50036 Tue 18 Jul 2023 21:31:02 SAST ]]> Physicochemical properties of water soluble unsymmetrical phthalocyanine-folic acid conjugates https://commons.ufh.ac.za/vital/access/manager/Repository/vital:50071 Tue 18 Jul 2023 21:31:00 SAST ]]> Carbon nanotube-enhanced photoelectrochemical properties of metallo-octacarboxyphthalocyanines https://commons.ufh.ac.za/vital/access/manager/Repository/vital:50953 (OH)2SiOCPc.
