✦ Synopsis

The kinetics of the reaction with iodomethane of the solvatochromic dye 4-[2-(Nmethyl-4,6-diphenylpyridiniumyl)]phenoxide 2, generated in situ from the corresponding Nmethyl-2,4-diphenyl-6-(4-hydroxyphenyl)pyridinium salt 4, was studied in various solvents and solvent mixtures, in search of a possible correlation between its reactivity and solvatochromism in solution.

## Abstract The interactions of a triblock copolymer containing a PEO central and two 4VP end blocks with PCBM were studied in different solvents. The interaction is too slow to be detected in toluene, but in THF a well‐defined charge transfer complex is formed, allowing the interaction kinetics to
