Room temperature phosphorescence quenching study of coumarins. Indirect determination of warfarin in pharmaceuticals [PDF]

, 2014
Room temperature phosphorescence of the 1-bromonaphthalene/b-cyclodextrin/cyclohexane inclusioncomplex was studied in the presence of coumarins: warfarin, coumarin, dicumarol and umbelliferone.The differences encountered when using right-angle or front ...

Reduction of self-quenching effect in organic electrophosphorescence emitting devices via the use of sterically hindered spacers in phosphorescence molecules

, 2001
The reduction of self-quenching effect by introduction of sterically hindered spacers in phosphorescence molecules was analyzed for a electrophosphorescence emitting device. The iridium complex of tris-ortho-cycloetalated compound exhibits a strong green

Complementary Fluorescence and Phosphorescence Study of the Interaction of Brompheniramine with Human Serum Albumin

, 2012
Binding of the antihistamine drug brompheniramine (BPA) to human serum albumin (HSA) is studied by measuring quenching of the fluorescence and room temperature phosphorescence (RTP) of tryptophan.

Uncaging Iridium(III) Complexes for Combined Photodynamic and Photoactivated Chemotherapy

Angewandte Chemie International Edition, EarlyView.
Light‐activatable iridium(III) anticancer prodrugs demonstrate how chalcogen coordination controls photoinduced therapeutic activity. Upon visible‐light irradiation, sulfur‐ and selenium‐based caging ligands undergo distinct oxygen‐dependent photoreactions that trigger ligand release and singlet oxygen generation, enabling combined photoactivated ...

Formation of Lanthanide Luminescent Aggregates With RNA Using Tripodal Europium [Eu(III)] BTA Self‐Assembled Complexes

Chemistry – A European Journal, EarlyView.
The two Eu(III) complexes of 1.Eu and 2.Eu, that were formed in situ, were used to bind to yeast RNA and A10 (RNA) in a buffered pH 7 solution. The interaction gave rise to changes in the lanthanide‐centered emission because of direct binding of these complexes, which resulted in aggregation of the RNA, as demonstrated using phase‐contrast and atomic ...

Crystallization‐Induced Emission Enhancements of Hybrid Butenolide‐Diphenylethenes

Chemistry – A European Journal, EarlyView.
Hybrid butenolide‐diphenylethene fluorophores show crystallization‐induced emission enhancement (CIEE), with substituents tuning solid‐state quantum yields up to 50%. One derivative, BuCM, displays dual‐state emissions (DSE), making this compact scaffold a promising platform for CIEE/DSE‐active fluorophores.

Monolithic Porous Polymer Architectures for Visible‐to‐UV Upconversion‐Driven Photochemical Reactions

Angewandte Chemie, Volume 138, Issue 40, 28 September 2026.
Porous polymer monoliths embedded with sensitizer–annihilator dye pairs enable efficient solid‐state visible‐to‐ultraviolet triplet–triplet annihilation‐based photon upconversion under low‐intensity blue and green light. Their co‐continuous porous architectures balance chromophore interactions with substrate accessibility, providing robust and tunable ...

Acrylamide Quenching of Trp Phosphorescence in Liver Alcohol Dehydrogenase: Evidence of Gated Quencher Penetration

, 2016
Notwithstanding the relevance of their biological function, slow motions in proteins, beyond the microsecond range, are still poorly understood and often elusive. We propose that acrylamide quenching of Trp phosphorescence of deeply buried residues, when

Fluorescent Colored Passive Radiative Cooling Based on Carbon Dots for Cooling Power Recovery

EcoEnergy, EarlyView.
We demonstrate colored passive radiative coolers consisting of a highly reflective porous ceramic base covered by an eco‐friendly luminescent carbon dot‐polymer composite, with two types of carbon dots enabling conversion of either ultraviolet or visible light, respectively.
