Photo- and PH-switchable fluorescent diarylethenes based on 2,3-diarylcyclopent-2-en-1-ones with dialkylamino groups

New dialkylamino groups-comprising diarylethenes of 2,3-diarylcyclopent-2-en-1-one (DCP) series have been synthesized and its photochromic, fluorescent as well as acidochromic features have been investigated. It was shown that photochromic properties of t

Stability of 1-phenacylpyridinium and 1-(2-hydroxy-2-phenylvinyl)pyridinium cations

1-Phenacylpyridinium cation, C5H5N+-CH2COC6H 4R-p, is the only tautomeric form detected in DMSO solution. This shows that the vicinity of the strong electron-acceptor pyridinium group has a minor effect on acidity of the methylene protons in 1-phenacylpyridinium salts. It was found that substitution in the benzene ring does not affect the tautomeric equilibrium. Although 1-(2-hydroxy-2-phenylvinyl)pyridinium cation is stabilized by conjugation, the ab initio calculated energies confirm the higher stability of the keto form (electron-acceptor substituents slightly increase stability of the enol form). It was found that 1-(2-hydroxy-2-phenylvinyl)pyridinium cation is not planar. Calculations show that electrostatic attraction between the onium nitrogen and hydroxy oxygen atoms takes place in this cation.
