Lanthanide luminescence from supramolecular hydrogels consisting of bio-conjugated picolinic-acid-based guanosine quadruplexes

•Guanosine quadruplex hydrogels were modified with ligand 1 enabling Eu(III) binding •Two of the gels both exceptionally stable and partially self-healable •Eu(III)-centered circularly polarized luminescence was observed for one hydrogel •The helical nature guanosine quadruplexes influenced Eu(III)-centered CPL The formation bio-inspired healable lanthanide luminescent is detailed. These materials are composed K(I)-stabilized (G4) that bio-conjugated to mannose-derived picolinic acid using boric chemistry (G4-1). supramolecular self-assembly between G4-1 europium (Eu(III)) confirmed, including use time-gated spectroscopy. most formed when ratio 1:1, this gel found retain a column. obtained samples further characterized techniques, such as scanning electron microscopy (SEM), circular dichroism (CD), We demonstrate (CPL) signal from can be even via long-range interaction, whereas rheology these exhibits their properties.
