Luminescent Radical-Excimer: Excited-State Dynamics of Luminescent Radicals in Doped Host Crystals.

Angewandte Chemie, 2019
The excited-state dynamics of the photostable luminescent organic radical (3,5-dichloro-4-pyridyl)bis(2,4,6-trichlorophenyl)methyl (PyBTM) doped in a host crystal was investigated by using optically detected magnetic resonance (ODMR) and time-resolved ...

The Nature of Excimer Formation in Crystalline Pyrene Nanoparticles

Journal of Physical Chemistry C, 2018
Pyrene is an exemplary conjugated organic chromophore with a strong propensity for self-association through an excited-state process known as excimer formation.

Highly Efficient Orange-Red/Red Excimer Fluorescence from Dimeric π–π Stacking of Perylene and Its Nanoparticle Applications

Journal of Physical Chemistry C, 2019
To achieve high-efficiency red excimer fluorescence, two novel perylene (PE) derivatives (mTPA-3PE and 2SF-3PE) are designed and synthesized with different monosubstituent triphenylamine (TPA) and spirofluorene (SF), respectively.

The 308-nm excimer laser stimulates melanogenesis via the wnt/β-Catenin signaling pathway in B16 cells

Journal of dermatological treatment (Print), 2019
Background: The mechanism of the 308-nm excimer laser in vitiligo treatment has not yet been adequately studied. In this study, we explored the role of the 308-nm excimer laser in treatment of vitiligo and the molecular mechanisms underlying melanin ...

Monodisperse π–π Stacking Anthracene Dimer under Pressure: Unique Fluorescence Behaviors and Experimental Determination of Interplanar Distance at Excimer Equilibrium Geometry

Advanced Optical Materials, 2018
Organic light‐emitting materials are centered on their excited states. However, excited‐state geometry is hardly solved. Herein, the planar distance of an anthracene excimer is determined by integrating a monodisperse dimeric anthracene stacking in ...
