Stimuli-responsive blue fluorescent supramolecular polymers based on a pillar[5]arene tetramer.
نویسندگان
چکیده
A tetraphenylethene-bridged pillarene tetramer with aggregation-induced emission properties forms an A4/B2-type supramolecular polymer and a gel with a symmetric neutral guest linker, showing a remarkable fluorescence emission enhancement in solution and the solid state and a good responsiveness to temperature and solvent composition.

متن کاملPillar[5]arene-based polymeric architectures constructed by orthogonal supramolecular interactions.
Ureidopyrimidinone functionalized pillar[5]arene (UPyP5) was synthesized and employed to complex with a bisparaquat derivative (G) to form supramolecular polymers at relatively high concentration. The orthogonal binding interactions including quadruple hydrogen bonding and host-guest interaction should play vital roles in the construction of this linear assembly.
متن کاملPhotoresponsive supramolecular self-assembly of monofunctionalized pillar[5]arene based on stiff stilbene.
We report a photoresponsive monofunctionalized pillar[5]arene based on stiff stilbene. The Z isomer, Z-1, tends to form self-complexing [1]pseudorotaxanes and [c2] daisy chains, whereas the E analog, E-1, forms supramolecular polymers.
