Merocyanine dyes with improved photostability.
Merocyanine dyes have proven valuable for live cell fluorescence imaging applications, but many structures have been limited by rapid photobleaching. We show that photostability is substantially enhanced for merocyanines having a cyano group at a specific position in the central polymethine chain. Evidence is presented that this is due to reduction in reactivity of the dyes with singlet oxygen....
متن کاملSubstituent effects in stilbene-based merocyanine dyes
Students in organic chemistry are taught a number of fundamental principles concerning the factors which govern the properties of organic compounds. Among these principles is the effect of substituents on the properties of aromatic rings, especially the benzene ring. For instance, we teach the students that the reactivity of the benzene molecule towards electrophilic substitution reactions is e...

15 صفحه اولPermanent Dipole Moment and Polarizability of a Gass of Merocyanine Dyes in Their Ground and First Excited Singlet State
The permanent dipole moment of a class of merocyanine dyes in their ground and first excited singlet state has been determined studying the influence of an external electric field on the absorption of the compounds in various solvents. Evaluation of the experimental results on the basis of the Onsager reaction field model also gives values for the polarizability in the ground and excited state,...
