New Insights on the Photochromism of 2-(2‘,4‘-Dinitrobenzyl)pyridine [PDF]

, 2002
The photochromic behavior of 2-(2‘,4‘-dinitrobenzyl)pyridine (α-DNBP) has been followed in poly(methyl methacrylate) (PMMA) films and benzene solutions to clarify the behavior of a precursor state, previously identified in studies on crystalline α-DNBP ...

Aggregate Engineering: Distinct Photophysical Properties and Organelle Targeting in Mesoionic Luminogens

Aggregate, Volume 7, Issue 5, May 2026.
A versatile platform based on a unique mesoionic luminogen, TPO, which features a new‐style D‐A structure, enables systematic investigation and modulation of structure–property relationships in aggregates. Through simple alkyl chain engineering, TPO derivatives control distinct aggregation structures and then regulate excited‐state energy dissipation ...

Diarylethene-modified nucleotides for switching optical properties in DNA

Beilstein Journal of Organic Chemistry, 2012
Diarylethenes were attached to the 5-position of 2’-deoxyuridine in order to yield three different photochromic nucleosides. All nucleosides were characterized with respect to their absorption and photochromic properties. Based on these results, the most

Novel synthesis and characterisation of 3,3-dimethyl-50-(2-benzothiazolyl)- spironaphth(indoline-2,30-[3H]naphth[2,1-b] [1,4]oxazine) derivatives [PDF]

, 2009
Novel modified spirooxazines (SOs) with additional chelating groups were synthesised and the crystal structure of one of these was determined. UV–vis spectroscopic characterization of the photoisomerization of the SO derivatives shows that the ...
