Ligands based upon 4-carboxamide-2-phenylquinoline derivatives have been synthesised with solubilising octyl hydrocarbon chains and tethered aromatic chromophores to give naphthyl (), anthracenyl () and pyrenyl () ligand variants, together with a non-chromophoric analogue () for comparison. (1)H NMR spectroscopic...

From Ligand to Phosphor: Rapid, Machine-Assisted Synthesis of Substituted Iridium(III) Pyrazolate Complexes with Tuneable Luminescence.

Photosynth Res. 1993 Aug;37(2):131-8. doi: 10.1007/BF02187471.

The relationship between charge recombination at Photosystem II (PS II), as indicated by millisecond luminescence, and PS II quantum yield was studied in spinach thylakoids during electron flow to methylviologen. Under the low magnesium conditions used, a decrease in...

Generation of oscillatory behavior in the Laisk model of photosynthetic carbon assimilation.

Photosynthesis research

PMID: 24435636
Photosynth Res. 1987 Jan;12(2):129-43. doi: 10.1007/BF00047943.

The metabolic pathways in photosynthesis are modelled as an interconnected series of chemical reactions representing the electron transfer system, the carbon reduction cycle and starch and sucrose synthesis according to the model of Laisk and Walker [Proc R Soc...

The slowly reversible component of nonphotochemical quenching of Chl fluorescence, ql, has been investigated in intact leaves and chloroplasts of spinach (Spinacia oleracea). In leaves, between 50 and 100% of ql (defined as the quenching that remained after at...

Dynamics of Xanthophyll-Cycle Activity in Different Antenna Subcomplexes in the Photosynthetic Membranes of Higher Plants (The Relationship between Zeaxanthin Conversion and Nonphotochemical Fluorescence Quenching).

Plant physiology

PMID: 12223884
Plant Physiol. 1997 Dec;115(4):1609-1618. doi: 10.1104/pp.115.4.1609.

The generation of nonphotochemical quenching of chlorophyll fluorescence (qN) in the antenna of photosystem II (PSII) is accompanied by the de-epoxidation of violaxanthin to antheraxanthin and zeaxanthin. The function of zeaxanthin in two mechanisms of qN, energy-dependent quenching (qE)...
