Halochromic and hydrochromic squaric acid functionalized perylene bisimide.
نویسندگان
چکیده
The functionalization of perylene bisimide by squaric acid afforded halochromic dyes with pronounced acidity. The dye senses solvent polarity, pH and humidity by means of pronounced changes in absorption spectra and thin film color through the intramolecular charge transfer between perylene and cyclobutene cores initiated by protonation/deprotonation.

Acetylene-linked macrocycles incorporating multiple perylene tetracarboxylic acid bisimide (PBI) chromophores have been synthesised and separated by recycling GPC. The very first example of such macrocycles, i.e., cyclic trimer 5, containing three PBI dyes self-assembles into highly ordered donut-shaped unique hexagonal nanopatterns on HOPG surfaces as revealed by atomic force microscopy (AFM).
متن کاملThe molecular recognition controlled stereomutation cycle in a dynamic helical assembly.
Perylene bisimide functionalized with a phosphate recognition unit assembles into a left-handed, right-handed or racemic helical assembly on binding with AMP, ATP and inorganic phosphates, respectively. Thus, competitive binding among these multivalent guests was utilized for completing an unprecedented helix mutation cycle in a dynamic supramolecular assembly.
