Advances in BODIPY Derivatives for Antibacterial Phototherapy

open access: yesAngewandte Chemie, EarlyView.
This review systematically summarizes the design strategies and structure‐activity relationships of BODIPY‐based antibacterial phototherapy, covering molecular engineering of small‐molecule photosensitizers and nanoplatforms, bacterial targeting and carrier design, and discussing the challenges and future perspectives associated with clinical ...

The occurrence of rapidly reversible non-photochemical quenching of chlorophyll a fluorescence in cyanobacteria

open access: yes, 2005
Cyanobacteria have previously been considered to differ fundamentally from plants and algae in their regulation of light harvesting. We show here that in fact the ecologically important marine prochlorophyte, Prochlorococcus, is capable of forming ...

Gold(III) Semiquinone Complexes: Synthesis, Structure, and Application in Photocatalysis

open access: yesAngewandte Chemie, EarlyView.
Au(III) catecholate complexes engage into electron donor acceptor (EDA) interactions with aryldiazonium salts, enabling single‐electron transfer under green light irradiation. Ligand‐centered one‐electron oxidation to stable semi‐quinone complexes provides a new platform for standalone Au(III) photoredox catalysis, as substantiated by the C–H arylation

Effects of shading on leaf physiology and morphology in the ‘Yinhong’ grape plants

open access: yesRevista Brasileira de Fruticultura, 2018
Shading is a practical measure to reduce the heat stress to grape trees in the summer. However, inappropriate shading will cause the reduction in leaf photosynthesis and consequently the retardation of growth for the plants or the loss of fruit yield and

Phosphoryl Radicals from Trivalent Iminyl Phosphines: A Photocatalytic Approach to N‐Phosphoryl Azetidines

open access: yesAngewandte Chemie, EarlyView.
Photochemically generated phosphoryl radicals from iminyl phosphines enable strain‐release addition to azabicyclobutanes, providing access to elusive N‐phosphoryl azetidines. Combined experimental, computational, and EPR studies reveal an unconventional water‐assisted photoredox pathway.

Color‐Pure Organic Luminophores: Characteristics, Definitions, Physical Basis and Fundamental Design Principles

open access: yesAngewandte Chemie, EarlyView.
Color‐pure all‐organic emitters, i.e., with narrow spectral characteristics, are intensively studied for high‐definition organic LEDs and multi‐color bioimaging. In order to guide targeted materials design, this educative review discusses spectral characteristics, proper definitions and units, and the physical basis of spectral broadening, to distill ...

The impact of organic selenium on the growth and physiological traits of Salvia miltiorrhiza Bunge. seedlings

open access: yesPlant, Soil and Environment
This study examined the impact of selenomethionine (SeMet) on the growth and physiological traits of Salvia miltiorrhiza seedlings. Application of SeMet significantly improved the photosynthetic performance by reducing stomatal limitation value (Ls) and ...

Non-photochemical quenching of P. tricornutum.

open access: yes, 2014
The changes in non-photochemical quenching of P. tricornutum cells grown under the LC (390 ppmv, pH 8.18) and HC (1000 ppmv, pH 7.82) and then both acclimated to different light levels (60, 200 and 460 µmol m−2 s−1) for 25–36 generations under high ...

Photochemical efficiency of PSII and photoprotective pigments in seedlings and adults of two Proteaceae with different shade tolerance from the Chilean temperate rain forest Eficiencia fotoquímica del PSII y pigmentos fotoprotectores en plántulas y adultos de dos Proteáceas con diferente tolerancia a la sombra del bosque lluvioso templado chileno

open access: yesRevista Chilena de Historia Natural, 2009
The seasonal variation in energy quenching parameters of photosystem II and photoprotective pigments were studied in seedlings and adults of two Proteaceae: a shade-intolerant species (Embotrium coccineum J.R. et G. Forster) and a shade-tolerant species (
