Photochromism of Diarylethenes in DNA-Quaternary Ammonium Ion Complex

Quaternary ammonium amalgams as Zintl ion salts and their use in the synthesis of novel quaternary ammonium salts.

dodecapeptide 5 does not seem to follow this trend, which may suggest that secondary interactions exist between the terpenoid and peptide moieties. Although we still need to perform many experiments to develop a reliable mechanistic model to explain the observed phenomenon, our preliminary observations show an interesting potential in this area and investigation along this line is in progress i...

Effects of the Peripheral Heteroaryl Substituents on the Photochromism of New Pyridine-Containing Diarylethenes

Three new unsymmetrical pyridine-containing diarylethenes with a variable peripheral heteroaryl unit were synthesized and their structures were determined by single-crystal X-ray diffraction analysis. The substituent effects of variable heteroaryl groups on the photochromic and fluorescence properties were systematically discussed. Thienyl and thiazyl could effectively enhance the cyclization q...
