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 ]]> Organosilicon compounds as fluorescent chemosensors for fluoride anion recognition https://commons.ufh.ac.za/vital/access/manager/Repository/vital:7241 Wed 08 May 2024 15:32:24 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 08 May 2024 15:31:06 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 08 May 2024 15:30:39 SAST ]]> MCD spectroscopy and TD-DFT calculations of a naphthalene-ring-bridged coplanar binuclear phthalocyanine dimer https://commons.ufh.ac.za/vital/access/manager/Repository/vital:49998 Wed 08 May 2024 15:29:37 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 Wed 08 May 2024 15:26:18 SAST ]]> Organosilicon compounds as fluorescent chemosensors for fluoride anion recognition https://commons.ufh.ac.za/vital/access/manager/Repository/vital:50938 Wed 08 May 2024 15:25:37 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 08 May 2024 15:24:11 SAST ]]> Synthesis, Characterization, and Electronic Structures of Porphyrins Fused with Polycyclic Aromatic Ring Systems https://commons.ufh.ac.za/vital/access/manager/Repository/vital:50827 Wed 08 May 2024 15:22:03 SAST ]]> Optically active BODIPYs https://commons.ufh.ac.za/vital/access/manager/Repository/vital:50833 Wed 08 May 2024 15:18:44 SAST ]]> Aggregation control of robust water-soluble zinc (II) phthalocyanine-based photosensitizers https://commons.ufh.ac.za/vital/access/manager/Repository/vital:50757 Wed 08 May 2024 15:16:32 SAST ]]> Photophysical and optical limiting properties of a novel distyryl-BODIPY with fused crown ether moieties https://commons.ufh.ac.za/vital/access/manager/Repository/vital:50749 Wed 08 May 2024 15:13:53 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 08 May 2024 15:12:33 SAST ]]> Flexible Metal–Porphyrin Dimers (M= MnIIICl, CoII, NiII, CuII) https://commons.ufh.ac.za/vital/access/manager/Repository/vital:50754 Wed 08 May 2024 15:10:04 SAST ]]> Photophysical properties of a novel styryl-BODIPY with a fused crown ether moiety https://commons.ufh.ac.za/vital/access/manager/Repository/vital:44736 Wed 08 May 2024 15:03:07 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 ]]> 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 ]]> 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.
