Synthesis and Functional Properties of Fluorinated Phosphonate‐Substituted Porphyrins: Excellent Photosensitizers and Robust Precursors for Photoactive Langmuir–Schaefer Films

open access: yesChemistry – A European Journal, EarlyView.
This is a comprehensive study of new family of high functionalized meso‐tetraarylporphyrins. A synthetic approach to phosphonate‐substituted fluorinated porphyrins was developed. These compounds were investigated with respect to singlet oxygen generation and photostability.

Bioinspired Design and Synthesis of Polyphenolic Star‐Like and Hyperbranched Polyester Models

open access: yesChemistry – A European Journal, EarlyView.
Gallotannin‐inspired star‐like and hyperbranched aromatic polyesters were synthesized from D‐glucose and ABn‐type phenolic acid monomers, such as protocatechuic acid. This bioinspired approach afforded polyphenolic polymeric nanoparticles able to encapsulate hydrophobic dyes, opening new perspectives for biobased encapsulation and delivery systems ...

Synthesis and Optical Properties of Diboron Complexes of 1,4‐Anthraquinone Derivatives

open access: yesChemistry – A European Journal, EarlyView.
1,4‐Diboron complexes exhibit near‐infrared fluorescence, in contrast to non‐emissive 1,5‐diboron analogues. Fluorescence quantum yields decrease with increasing electron‐donating substituents, attributed to enhanced nonradiative decay via intramolecular PeT.

Asymmetric Diphosphane Dioxides With A–π–A–π’–D Scaffolds for High‐Purity Deep‐Blue Luminescence

open access: yesChemistry – A European Journal, EarlyView.
Diphosphane dioxide‐based luminophores with donor–π–acceptor– π’–acceptor scaffold enable efficient deep‐blue emission from tunable charge‐transfer states affording high photoluminescence up to 95%. OLEDs reach EQE 4.9%, aided by triplet–triplet annihilation, highlighting a practical route to high‐performance blue emitters.

Fluorogenic Sydnones for Bioorthogonal Labeling of DNA

open access: yesChemistry – A European Journal, EarlyView.
Conjugates of sydnones with cyanine‐styryl dyes combine bioorthogonal reactivity with fluorogenicity. The reactivity with bicyclo[6.1.0]non‐4‐yne (BCN)‐modified DNA showed second‐order rate constants of up to k2 = 2,300 M−1s−1 and fluorescence turn‐on by one magnitude of order.
