Response of Tb(III) and Eu(III) centered luminescence on phase transitions in aqueous solutions of triblock copolymers

- Aggregation of triblock copolymers affects luminescence of Tb and Eu complexes.
- The luminescence quenching results from the complex formation equilibrium shift.
- The equilibrium shift depends on the aggregation mode of triblock copolymers.
- Key impact of ligand's structure in aggregation induced quenching of luminescence.
