Flavylium compounds are a well-known family of pigments because they are prevalent in the
plant kingdom, contributing to colors over a wide range from shades of yellow-red to blue in …

Flavylium compounds are versatile molecules that comprise anthocyanins, the ubiquitous
colorants used by Nature to confer colour to most flowers and fruits. They have found a wide …

Two novel [2] rotaxanes, comprised of a dibenzo [24] crown-8 (DB24C8) macroring bound
mechanically to a chemical “dumbbell” possessing two different recognition sites viz …

Chemists are now able to emulate the ideas and instruments of mathematics and computer
science with molecules. The integration of molecular logic gates into small arrays has been …

Independently of the natural or synthetic origin, flavylium derivatives follow the same
network of chemical reactions. Actually, the flavylium cation is stable only at low pH values …

We describe the photochemical behavior of aqueous solutions containing the Co (CN) 63-
complex ion and the trans-chalcone form Ct of the 4 '-methoxyflavylium ion (A H+). It is …

A multiphotochromic hybrid system is presented in which a light‐driven overcrowded alkene‐
based molecular rotary motor is connected to a dithienylethene photoswitch. Ring closing of …

The reversibly switchable trans‐chalcone/flavylium photochromic system was successfully
coupled to the complexation equilibrium of a drug‐cucurbit [7] uril host–guest assembly …

Spatially and temporally localized delivery is a promising strategy to circumvent adverse
effects of traditional drug therapy such as drug toxicity and prolonged treatments. Stimuli …

Substituent effect on the photochromic reactivity of bis (2-thienyl) perfluorocyclopentenes
was examined. Introduction of phenyl groups having electron-donating substituents on the …
