Excimer Formation in the Interlayer Region of Arene-Derivatized Zirconium Phosphonates
TLDR
Photophysical investigations are reported for two arene-derivatized zirconium phosphonates (layered solids) and the chromophore groups that are attached within the interlayer region of these materials are seen to form excimer pairs.Abstract:
Photophysical investigations are reported for two arene-derivatized zirconium phosphonates (layered solids). The chromophore groups that are attached within the interlayer region of these materials are seen to form excimer pairs. Whereas the naphthalene-containing system exhibits both monomer and excimer fluorescence, the potentially greater overlap of chromophores for the system containing anthracene-pendant groups causes that compound to only show excimer fluorescence.read more

Regulation of π-Stacked Anthracene Arrangement for Fluorescence Modulation of Organic Solid from Monomer to Excited Oligomer Emission
Tomoaki Hinoue,Yuta Shigenoi,Misa Sugino,Yuji Mizobe,Ichiro Hisaki,Mikiji Miyata,Norimitsu Tohnai,Norimitsu Tohnai +7 more
TL;DR: The construction and precise control of the face-to-face π-stacked arrangements of anthracene fluorophores in the crystalline state led to a remarkable red shift in the fluorescence spectrum due to unprecedented excited oligomer formation.

TL;DR: Covalent monolayer sheets in 2 hours: spreading of threefold anthracene-equipped shape-persistent and amphiphilic monomers at the air/water interface followed by a short photochemical treatment provides access to infinitely sized, strictly monolayered, covalent sheets with in-plane elastic modulus in the range of 19 N/m.

Anomalous Anthracene Arrangement and Rare Excimer Emission in the Solid State: Transcription and Translation of Molecular Information
TL;DR: A novel molecular arrangement of anthracene moieties and the corresponding rare solid-state excimer emission is obtained by utilization of a ternary system and shows the modulation of the solid- state emission mode depending on the adducts.

Efficient photoinduced charge separation in layered zirconium viologen phosphonate compounds
TL;DR: In this paper, a photoinduced charge separation has been observed in layered zirconium viologen phosphonate compounds, i.e., ZrPV(X), where the primary photoprocess involves a viologens-centered excitation, followed by oxidation of a halide anion.
