Symmetry breaking fluctuations split the porphyrin Q bands [PDF]
arXivPorphyrins offer a malleable and cost-efficient platform to sculpt bioinspired technologies with tunable charge transfer, energy conversion, and photocatalytic properties. Yet, despite decades of research, the physical mechanisms that determine their electronic spectra remain elusive. Even for metal-free porphyrins, no consensus exists on the origin of

Advanced Science, EarlyView.The synthesis of a range of squaraine dyes is reported with maximum absorption in solution above 1100 nm. Near‐infrared sensitive organic photomultiplication photodetectors are developed. Photomultiplication occurs via squaraine hole trap‐induced injection of electrons from the external circuit.

Electrochemistry and spectroelectrochemistry of iron porphyrins in the presence of nitrite [PDF]
, 2001 The reaction of nitrite with ferric and ferrous porphyrins was examined using visible, infrared and NMR spectroscopy. Solutions of either ferric or ferrous porphyrin were stable in the presence of nitrite, with only complexation reactions being observed.
