Strained Porphyrin Tape-Cycloparaphenylene Hybrid Nanorings [PDF]
, 2022 V-shaped porphyrin dimers, with masked para-phenylene bridges, undergo efficient oxidative coupling to form meso-meso linked cyclic porphyrin oligomers. Reductive aromatization unmasks the para-phenylenes, increasing the strain.

Advanced Healthcare Materials, EarlyView.Under NIR irradiation, PTCPP generates ROS to eliminate MRSA biofilms and promote M1 macrophage polarization for phagocytosis. After bacterial clearance, the material is phagocytosed by macrophages, shifting their polarization to M2 phenotype via metabolic reprogramming, which synergistically enhances anti‐infection therapy and wound healing.

Advanced Healthcare Materials, EarlyView.Three‐dimensional bioprinting transforms breast cancer modeling from simple constructs into spatially organized, multicellular, perfused, and patient‐derived platforms. This review shows how bioinks, cellular composition, architecture, and flow govern tumor behavior and drug response, while revealing why complexity alone is insufficient without ...

Obstruction of photoinduced electron transfer from excited porphyrin to graphene oxide: a fluorescence turn-on sensing platform for iron (III) ions. [PDF]
PLoS ONE, 2012 A comparative research of the assembly of different porphyrin molecules on graphene oxide (GO) and reduced graphene oxide (RGO) was carried out, respectively. Despite the cationic porphyrin molecules can be assembled onto the surfaces of graphene sheets,

, 2005 Corroles, porphyrin analogues, are the center of a rapidly growing field of research. By virtue of a missing meso-carbon, corroles retain the aromaticity of porphyrins, but become tribasic ligands in place of the dibasic porphyrin.
