Dual-responsive self-assembly of a bola-type supra-amphiphile constructed from a new pillar[6]arene-based recognition motif in water and its application in controlled release

A new host–guest system based on a water-soluble pillar[6]arene (WP6) was designed and its application in the construction of dual-responsive self-assembly of a bola-type supra-amphiphile and application in controlled release was achieved.
