In a series of heterodinuclear complexes in which a Pt(PPh3)2(catecholate) chromophore is covalently linked to a lanthanide tris(diketonate) unit, sensitised near-IR emission from Yb(III), Nd(III) and Er(III) occurs on excitation of the Pt(II) chromophore at 520 nm.

A core–shell approach that utilizes a high-surface-area conducting core and an outer semiconductor shell is exploited here to prepare p-type dye-sensitized solar energy cells operate with minimal applied bias. Photocathodes were prepared by coating thin films of nanocrystalline indium tin oxide 0.8 nm Al2O3 seeding layer, followed the chemical growth nonstoichiometric strontium titanate. Films ...

A one-pot cyclisation/oxidation process results in a new constrained-cavity Schiff-base dipyrrin macrocycle and allows access to Li, Fe, Zn complexes of this unique chromophore.

Differences in histidine protonation result contrasting dynamics of the PCB chromophore AnPixJg2. The doubly protonated form induces heterogeneity, which is absent singly form. They can be distinguished using CD spectroscopy.

Fluorescent proteins (FPs) have revolutionised the life sciences, but chromophore maturation mechanism is still not fully understood. Here we photochemically trap at a crucial stage and structurally characterise intermediate.

Green fluorescent protein (GFP), together with its family of variants, is the most widely used for in vivo imaging. An investigation influence fluorine and methoxy substituents on electronic structure GFP chromophore.

Chromophore shielding is critical for twisted single core perylene bisimides used as non-fullerene acceptors in organic solar cells. Inherent chirality becomes only important close packing chromophores crystal structure analyses reveal.

Here we present the study of the chromophore structure of the purple chromoprotein from Condylactis gigantea. Tandem mass spectrometry and H and C NMR of the chromopeptide reveal that the protein contains a chromophore with a chemical structure identical to that of the red fluorescent protein from Discosoma sp. A single A63G substitution demonstrates that the nature of the first amino acid of t...

Five nucleic acid binding cyanine dyes were synthesized and their photophysical characteristics evaluated. Changing a heteroatom in the chromophore caused major differences properties between improving upon available commercial products.

Quartet states, generated after photoexcitation of chromophore–radical dyads, are promising for applications in quantum sensing. We demonstrate the potential trityl radicals improving their coherence properties and spectral addressability.
