Abstract

A fluorescent responsive BMP32C10-based cryptand host was successfully synthesized by introducing a 4-methylcoumarin group to the third arm of the cryptand. The cryptand was able to undergo [2+2] photodimerization on UV irradiation (λ = 365 nm) and, based on the photodimerization and host–guest interaction, a new supramolecular polymer was constructed in a convenient manner.
