The quest to find milder and more sustainable methods to generate highly reactive, carbon-
centred intermediates has led to a resurgence of interest in radical chemistry. In particular …

Today's technology is not possible without optoelectronic devices such as light-emitting
diodes, transistors and solar cells. These basic units of modern electronic appliances may …

Quenching of excited singlet and triplet states of many substances by ground state
molecular oxygen produces singlet oxygen, the lowest electronically excited singlet state of …

Sensitization-initiated electron transfer (SenI-ET) describes a recently discovered
photoredox strategy that relies on two consecutive light absorption events, triggering a …

Polycyclic aromatic hydrocarbons (PAH), also known as polynuclear aromatic hydrocarbons
or polyarenes, constitute a large class of organic compounds. They are formed and released …

The triplet pair is the key functional unit in triplet–triplet annihilation photon upconversion.
The same molecular properties that stabilize the triplet pair also allow dimers to form on the …

The structural factors affecting triplet–triplet annihilation (TTA) at the molecular level are not
well-understood. Here, our steady-state photoluminescence and transient absorption results …

Ru (II) complexes possessing new tridentate ligands with extended π systems, pydppx (3-
(pyrid-2′-yl)-11, 12-dimethyl-dipyrido [3, 2-a: 2′, 3′-c] phenazine) and pydppn (3-(pyrid …

Time-resolved laser flash spectroscopy with transient detection by time-resolved UV− vis, IR,
and EPR has been employed to investigate the photochemistry and photophysics of a series …

For the tumour photosensitisers m-THPP, m-THPC, and m-THPBC in methanol the following
photophysical properties have been measured: absorption and fluorescence spectra, ES …
