Novel rare earth fluorescent supramolecular polymeric assemblies constructed by orthogonal pillar[5]arene-based molecular recognition, Eu(iii)-coordination and π-π donor-acceptor interactions.

Here, a facile strategy is provided to prepare pillar[5]arene-based fluorescent supramolecular polymer assemblies by orthogonal Eu(iii)-coordination and two non-interfering noncovalent interactions.
