“…These nanohybrids have promising applications in solar cells [9], photocatalytic oxidations [10], photo-generation of reactive oxygen species (ROS) [11], microbial photodynamic therapy for biomedical [12], and food applications [13]. MP-CNT hybrids also showed good performance in electrocatalysis for an oxygen reduction reaction (ORR) [14] and CO 2 reduction reaction (CO 2 RR) [15], and in electroanalysis as bio-analyte sensors [16]. In the context of redox catalysis, MP-CNT hybrids showed efficient environmental pollutant oxidations [17] or as catalytic antioxidants, tailoring catalase/dismutase mimics [18].…”

To unveil and shape the molecular connectivity in (metallo)porphyrin–carbon nanotube hybrids are of main relevance for the multiple medicinal, photoelectronic, catalytic, and photocatalytic applications of these materials. Multi-walled carbon nanotubes (MWCNTs) were modified through 1,3-dipolar cycloaddition reactions with azomethine ylides generated in situ and carrying pentafluorophenyl groups, followed by immobilization of the β-amino-tetraphenylporphyrinate Zn(II). The functionalities were confirmed via XPS and FTIR, whereas Raman spectroscopy showed disruptions on the graphitic carbon nanotube surface upon both steps. The functionalization extension, measured via TGA mass loss and corroborated via XPS, was 0.2 mmol·g−1. Photophysical studies attest to the presence of the different porphyrin–carbon nanotube connectivity in the nanohybrid. Significantly different emission spectra and fluorescence anisotropy of 0.15–0.3 were observed upon variation of excitation wavelength. Vis-NIR absorption and flash photolysis experiments showed energy/charge transfer in the photoactivated nanohybrid. Moreover, evidence was found for direct reaction of amino groups with a carbon nanotube surface in the presence of molecular dipoles such as the zwitterionic sarcosine amino acid.

In situ growth of a cobalt porphyrin-based covalent organic framework on multi-walled carbon nanotubes for ultrasensitive real-time monitoring of living cell-released nitric oxide

Abstract: Due to the synergy of atomic-level periodic structural features of COF-366-Co and high conductivity of MWCNTs, a MWCNTs@COF-366-Co electrochemical biosensor has been successfully used to sensitively monitor NO released from HUVECs.
