Electronic Structure of an Iron-Porphyrin Derivative on Au(111) [PDF]
J. Phys.: Condens. Matter 31, 044002 (2019), 2018 Surface-bound porphyrins are promising candidates for molecular switches, electronics and spintronics. Here, we studied the structural and the electronic properties of Fe-tetra-pyridil-porphyrin adsorbed on Au(111) in the monolayer regime. We combined scanning tunneling microscopy/spectroscopy, ultraviolet photoemission, and two-photon photoemission to

Wafer-scale synthesis of monolayer two-dimensional porphyrin polymers for hybrid superlattices
Science, 2019 Single-layer porphyrin polymerization Two-dimensional polymers can be made as monolayer sheets through controlled synthesis at an interface. However, it is often difficult to create intact sheets over large areas that can be transferred onto substrates ...

Signature of gate-tunable magnetism in graphene grafted with Pt-porphyrins [PDF]
Phys. Rev. B 93, 045403 (2016), 2013 Inducing magnetism in graphene holds great promises, such as controlling the exchange interaction with a gate electrode and generating exotic magnetic phases. Coating graphene with magnetic molecules or atoms has so far mostly lead to decreased graphene mobility.

Porphyrin photosensitizers in photodynamic therapy and its applications
OncoTarget, 2017 In 1841, the extraction of hematoporphyrin from dried blood by removing iron marked the birth of the photosensitizer. The last twenty years has witnessed extensive research in the application of photodynamic therapy (PDT) in tumor-bearing (or other ...

The effect of porphyrins on normal and transformed mouse cell lines in the presence of visible light
Brazilian Journal of Medical and Biological Research, 2001 Photodynamic therapy consists of the uptake of a photosensitizing dye, often a porphyrin, by tumor tissue and subsequent irradiation of the tumor with visible light of an appropriate wavelength matched to the absorption spectrum of the photosensitizing ...
