Dye sensitized solar cell action of Sn(IV)tetrakis(4-pyridyl) porphyrins as a function of axial ligation and pyridine protonation

Three-Dimensional van der Waals Heterostructure-Based Nanocages as Supersensitive 3-Hydroxy-2-butanone Gas Sensors at Room Temperature

“…The unique sensing performance could be designed through the axial connection of the porphyrin ring and central metal oxide, which allowed for being applied in such hi-tech applications as gas sensors. 15 Therefore, composite materials with a high specific area and modifiable function were still highly sought after for developing high-performance room-temperature gas sensors. 16 In this work, a strategy based on 3D nanoporous tetra-4-aminophenyl porphyrin-based covalent organic frameworks@SnO 2 @multiwalled carbon nanotubes (TAPP-COFs@ SnO 2 @MWCNTs) nanocage structural sensing materials as supersensitive gas sensors for detecting 3H-2B, built with van der Waals heterostructure-based composite nanotubes, was demonstrated.…”

“…They were able to regulate the electron density without changing the molecular structure and stability. The unique sensing performance could be designed through the axial connection of the porphyrin ring and central metal oxide, which allowed for being applied in such hi-tech applications as gas sensors .
