TL;DR: Fluorescence quenching and excitation spectra indicate that the singlet energy transfer is efficient for the dyad triplet photosensitizers, and Nanosecond time-resolved transient absorption spectroscopy has confirmed that the triplet excited states of the dyads are distributed on both the energy donor and acceptor.

TL;DR: iodo-Bodipy derivatives that show strong absorption of visible light and long-lived triplet excited states as organic catalysts for photoredox catalytic organic reactions are used for two photocatalyzed reactions mediated by singlet oxygen.

TL;DR: The results are useful for preparation of transition metal complexes that show strong absorption of visible light in the NIR region with long-lived triplet excited states and for the application of these complexes in photocatalysis and theranostics such as simultaneous photodynamic therapy (PDT) and luminescent bioimaging.

TL;DR: The results indicate that the photovoltaic performance can be finely modulated through structural engineering of the dyes, which can not only modulate light absorption and energy levels, but also have an impact on dye aggregation and interfacial charge recombination of electrons at the interface of titania, electrolytes, and/or oxidized dye molecules.

TL;DR: A new excited state intramolecular proton transfer chromophore of naphthalimide (NI) conjugated 2-(2-hydroxyphenyl) benzothiazole (HBT) was prepared which shows red shifted absorption and long-lived triplet excited states.
