A subphthalocyanine-pyrene dyad: electron transfer and singlet oxygen generation
, 2018 A light harvesting subphthalocyanine-pyrene dyad has been synthesized and characterized by linking pyrene (Py) with subphthalocyanine (SubPc) at its axial position with the B-O bond through the para position of the benzene group.

Photobiochemistry and Photobiophysics, 1986 Tryptophan photosensitization was used to determine the quantum yield of singlet oxygen production by porphyrins irradiated with ultraviolet or visible light in phosphate buffer at pH 7.0. From a preliminary study of aggregation of these dyes, it was established that uroporphyrin, hematoporphyrin and deuteroporphyrin allowed to investigate the ...

Singlet Oxygen Chemistry in Water. 2. Photoexcited Sensitizer Quenching by O2 at the Water−Porous Glass Interface [PDF]
The Journal of Physical Chemistry B, 2008 Insight into the O2 quenching mechanism of a photosensitizer (static or dynamic) would be useful for the design of heterogeneous systems to control the mode of generation of 1O2 in water. Here, we describe the use of a photosensitizer, meso-tetra(N-methyl-4-pyridyl)porphine (1), which was adsorbed onto porous Vycor glass (PVG). A maximum loading of 1.1

Advanced Science, EarlyView.Engineered phage‐based trifunctional nanofibers are developed for synergistic biofilm eradication. Biofilm‐binding phages, armed with AuNPs and TCPP, serve as both warheads and scaffolds, endowing the phototherapy agents with biofilm‐anchoring ability. Upon light irradiation, AuNPs induce photothermal therapy, while TCPP generates 1O2 for photodynamic ...

Advanced Science, EarlyView.High‐throughput screening led to the identification of 67 Z‐scheme heterojunctions (comprising 2D magnetic transition metal halides and non‐magnetic transition metal chalcogenides). For CrI3/MoTe2 and CrI3/WTe2, electronic structure analysis demonstrated that synergistic crystallographic point group and built‐in electric field effects generate a ...

Advanced Science, EarlyView.Faster phenol photolysis at the air–water interface arises from two cooperative factors: a more favorable initial microenvironment for solvent‐side electron stabilization, which lowers CI access, and a more labile hydrogen‐bond network, which more readily reorganizes to stabilize the dark‐state intermediate.
