Localized Accumulation of Tri‐n‐Propylamine Prolongs Electrochemiluminescence for Tumor Model Spheroid Analysis

open access: yesAngewandte Chemie, EarlyView.
Here, we enhance the electrochemiluminescence imaging of cellular spheroids using [Ru(bpy)3]2+/TPrA chemistry. Our strategy, which involves pre‐incubation with TPrA, enables high‐resolution, long‐term visualization of cellular spheroids without phototoxicity.

A Cocktail Approach Toward Tunable Organic Afterglow Systems [PDF]

open access: yes, 2021
In this work, a cocktail approach toward tunable organic long-lived luminescence materials in solid, solution, and gel states is proposed. The tunable long-lived luminescence (τ > 0.7 s) is realized by controlling the energy transfer via manipulating the photo-induced isomerization of the energy acceptor (5).

Structural and Compositional Effects on the Scintillation Properties of Fast Emitting Metal‐Organic Frameworks

open access: yesAdvanced Science, EarlyView.
The crystalline structure, the atomic numbers of the constituent elementsand the size of MOF crystals each influence their photoluminescence and scintillation properties in distinct ways. Together, these factors provide valuable guidelines for designing systems with optimized performance and tunable timing characteristics, arising from the synergistic ...
