## Title

  title_type: original

## Description

- description: 'Optical codes generated from the emission lifetimes of lanthanide
    complexes have received considerable attention for their potential application
    in multiplexed bioimaging and anti-counterfeiting. However, such tunable lifetimes
    are limited to short ranges (0.01−1 ms). Herein, we describe a method that extends
    the emission lifetime using dynamic molecular triplet excitons in aggregation
    systems composed of lanthanide complexes. To demonstrate the conceptual method,
    molecular crystals comprising lutetium (Lu3+) and luminescent lanthanide (europium:
    Eu3+ or terbium: Tb3+) complexes with two organic ligands (2,2,6,6-tetramethyl-3,5-heptanedionate
    and 2,7-bis(diphenylphosphoryl)phenanthrene) were prepared. These molecular crystals
    exhibited persistent emission via slow triplet exciton migration between the phenanthrene
    units. The extended degree of the lifetime could be controlled between 1 and 152
    ms by ligand modifications. This proposed lifetime-tuning method should significantly
    expand the encoding capacity of lanthanide complexes.'
