Abstract Ultraviolet (UV, λ< 400 nm) light is essential for various photochemical reactions,
but its intensity in the solar spectrum is very low, and light sources that artificially generate …

Light-absorbing organic molecules are useful components in photocatalysts, but it is difficult
to formulate reliable structure–property design rules. More than 100 million unique chemical …

In recent years, various organic dyes have been used as photosensitizers for the
photocatalytic reduction of water and carbon dioxide, which is a sustainable approach for …

Colloidal quantum dots (QDs) with core/shell architecture can offer tailored electronic and
optical properties which are promising for various optoelectronic applications. Here, we …

Efficient triplet–triplet annihilation-based photon upconversion (TTA-UC) from visible to UV
light without using heavy metals is still a challenging task. Here we achieve a record-high …

The development of simple coumarin-based organic dyes loaded over TiO 2 is found to
possess great potential for efficient photocatalytic hydrogen generation. Herein, we studied …

In this study, we explore the untapped potential of ketocoumarins as photosensitizers for
light driven hydrogen evolution. Through the synthesis of a library of novel ketocoumarins …

A series of novel 2-quinolone ligands and their corresponding Eu (III) complexes were
prepared. The effect of different solvents, different ligand concentrations and different …

An efficient method is introduced based on the copper (II) acetate catalyzed one-pot
multicomponent synthesis of novel chromeno [4, 3-b] pyrano [3, 4-e] pyridine-6, 8-dione …

We prepared an orthogonal electron donor/acceptor dyad (NI–Py) with perylene (Py) as
electron donor and 4-aminonaphthalimide (NI) as an electron acceptor. The molecule …
