Flow-through room temperature phosphorescence optosensing for the determination of lead in sea water

open access: yes, 1999
The chelates formed between the heavy metal ion Pb(II) and the reagents 8-hydroxy-5-quinolinesulphonic acid, 8-hydroxy-7-quinolinesulphonic acid and 8-hydroxy-7-iodo-5-quinolinesulphonic acid exhibit strong room temperature phosphorescence (RTP) if ...

Synthesis, Solubilization, and Photophysical Properties of Polyfluorinated Pentacene Dimers

open access: yesJournal of Physical Organic Chemistry, Volume 39, Issue 7, July 2026.
The synthesis and photophysical analysis of polyfunctionalized pentacene dimers is described. Polyfluorination is employed to modulate the polarizability and to investigate the effects on the mechanism of singlet fission (SF). ABSTRACT A polyfluorinated pentacene dimer, linked with a 1,3‐diethynylphenylene spacer, was synthesized to investigate the ...

Bond and Antibond Resonances: A Unified Framework for Singlet Biradical Character

open access: yesChemistry – A European Journal, Volume 32, Issue 23, 16 June 2026.
The electronic structure of a variety of singlet biradicaloids may be described in the Lewis picture using single antibonds as the central bonding motif. In conjunction with a consistent set of biradical indicators, we can resolve some long‐standing disputes over the biradical character of molecules such as O3 and S2N2.

Tuning the Photochemistry of Entatic State Model Systems

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 9, 3 June 2026.
We present the photochemistry of the entatic state model [Cu(DMEGqu)2]+/2+, a copper guanidino‐quinoline complex pair. By transient IR and UV/Vis spectroscopy, we obtained the lifetimes of the different excited states. We show that the structural effect of the guanidine tunes the photochemistry of this entatic state model.

IN4MER Biomaterial Ink: A Phosphorescent Biosensing Biomaterial Ink for Multiple Analytes (Glucose, Lactate, Oxygen) Measurements and Temperature Sensing Applications

open access: yesAdvanced Functional Materials, Volume 36, Issue 48, 15 June 2026.
Multianalyte, real‐time monitoring of bioprinted scaffolds remains challenging. Phosphorescence‐lifetime–based, optically responsive microparticles are embedded in diverse printable hydrogels (κ‐carrageenan, GelMA, PEGDA) to form biomaterial inks that report oxygen, glucose, lactate, and temperature.

Molecular Persistent Room-Temperature Phosphorescence from Tetraarylaminoboranes

open access: yes
Herein, we report the synthesis, molecular structure, and optical features of tetrarylaminoboranes 1 (Mes2B-N­(Ph)­(C10H7)) and 2 (Mes2B-N­(Ph)­(C14H9)). In the solution state, 1 shows aggregation-induced emission enhancement and color switching, while 2
