Two-component design strategy: TADF-Type organic afterglow for time-gated chemodosimeters

Guangming Wang et al.

Summary: Organic afterglow materials have strong capability to avoid fluorescence interference, making them suitable for highly sensitive analysis. However, there is limited research on afterglow materials with specific analysis properties. In this study, reactive pyrylium salts were doped into phenyl benzoate matrices to fabricate TADF-type organic afterglow materials. These materials demonstrated improved afterglow efficiency, maintained afterglow emission lifetimes, and exhibited high afterglow quantum yields. They also functioned as time-gated chemodosimeters specifically for amine-containing compounds even in the presence of strong fluorescence backgrounds.

Dielectric control of reverse intersystem crossing in thermally activated delayed fluorescence emitters

Alexander J. Gillett et al.

Summary: Thermally activated delayed fluorescence (TADF) materials are influenced by the dielectric environment, especially in materials with higher dipole moments. Environmental reorganization after excitation can decrease the activation energy for reverse intersystem crossing, leading to an increased rate of reverse intersystem crossing.

Shining Light on the Solution- and Excited-State Dynamics of Chalcogenopyrylium Polymethine Dyes

Lauren E. Rosch et al.

Summary: Despite 40 years of research on photophysical properties, significant gaps remain in understanding chalcogenopyrylium polymethine dyes. This study fills in these gaps through experiments on a family of dyes, revealing that structural and electronic changes can affect the photophysics of these dyes. The excited states of these dyes have short lifetimes with rapid relaxation processes, and they do not exhibit any triplet transient processes. Additionally, rotation of the pyran ring about the methine backbone is a critical factor that distinguishes the dynamics of these dyes from more rigid analogues.
