Excimer Formation in the Non‐Van‐Der‐Waals 2D Semiconductor Bi2O2Se

Advances in Materials, 2022
The layered semiconductor Bi2O2Se is a promising new‐type 2D material that holds layered structure via electrostatic forces instead of van der Waals (vdW) attractions.

FAP-α-Instructed Coumarin Excimer Formation for High Contrast Fluorescence Imaging of Tumor.

Nano letters (Print), 2022
Emissive excimers, which are formed by planar polycyclic aromatic fluorophores (e.g., coumarin), enable high contrast tumor imaging. However, it is still challenging to "turn on" excimer fluorescence in physiological dilute solutions.

Pyrene-based monomer-excimer dual response organosilicon polymer for selective detection of 2,4,6-trinitrotoluene (TNT) and 2,4,6-trinitrophenol (TNP)

Materials Chemistry Frontiers, 2022
The formation or destruction of pyrene excimer with strong emission change make it a versatile fluorophore to construct excimer emission-based fluorescence probes for various analytes detection.

Dynamics of Anthracene Excimer Formation within a Water-Soluble Nanocavity at Room Temperature.

Journal of the American Chemical Society, 2021
Excited anthracene is well-known to photodimerize and not to exhibit excimer emission in isotropic organic solvents. Anthracene (AN) forms two types of supramolecular host-guest complexes (2:1 and 2:2, H:G) with the synthetic host octa acid in aqueous ...

Evaluation of combined excimer laser and platelet‐rich plasma for the treatment of nonsegmental vitiligo: A prospective comparative study

Journal of Cosmetic Dermatology, 2020
Excimer laser therapy of vitiligo generally takes months to years to achieve excellent outcomes. Platelet‐rich plasma is an autologous preparation with a focus on various growth factors that can help with vitiligo repigmentation.

A key stacking factor for the effective formation of pyrene excimer in crystals: degree of π–π overlap

, 2020
In order to facilitate pyrene (PY) excimer formation in solids, several imidazole-containing PY derivatives were designed and synthesized. Among them, a new compound 1,4,5-triphenyl-2-(pyren-1-yl)-4,5-dihydro-1H-imidazole (IM-PY) was achieved with two ...

Dynamic Transition between Monomer and Excimer Phosphorescence in Organic Near‐Infrared Phosphorescent Crystals

Advances in Materials
Achieving efficient near‐infrared room‐temperature phosphorescence of purely organic phosphors remains scarce and challenging due to strong nonradiative decay. Additionally, the investigation of triplet excimer phosphorescence is rarely reported, despite

Ultrafast Exciton Delocalization, Localization, and Excimer Formation Dynamics in a Highly Defined Perylene Bisimide Quadruple π-Stack.

Journal of the American Chemical Society, 2018
An adequately designed, bay-tethered perylene bisimide (PBI) dimer Bis-PBI was synthesized by Pd/Cu-catalyzed Glaser-type oxidative homocoupling of the respective PBI building block.
