Tough Double Metal-ion Cross-linked Elastomers with Temperature-adaptable Self-healing and Luminescence Properties

Persistent room temperature phosphorescence films based on star-shaped organic emitters

“…14,43–45 Especially, the preparation of their thin films is always a critical and challenging task, while thin films with desirable optical properties are highly desired for many important practical applications. 14,43,46,47 In addition, in film states, the active vibration/diffusion motions of phosphors may quench the long-live triplet excitons. 43 Although several blend films of small molecular phosphors with rigid polymer matrices or host molecules have been reported, 3,8,29–31,48–51 it is hard to control the homogeneity of these doped films due to inevitable phase separation in two-component systems 52 .…”

Unprecedented toughness in transparent, luminescent, self-healing polymers enabled via hierarchical rigid domain design

“…3c and Table S2, ESI†). 11–13,21–27 Even compared with the non-luminescent strong and tough self-healing elastomers reported in the literature, the toughness of our materials is still unprecedented (Fig. 3d).…”

Three-Dimensional Shape Transformation of Eu3+-Containing Polymer Films through Modulating Dynamic Eu3+-Iminodiacetate Coordination

“…Dynamic metal–ligand coordination has been broadly used to fabricate stimuli-responsive materials. − Among many dynamic metal–ligand coordinations, the disruption and reformation of luminescent lanthanides with ligands can usually switch the mechanical states of the polymers in couple with their luminescence emission of lanthanides, like Eu 3+ . − We recently developed multistimuli-responsive polymer hydrogels and elastomers using the dynamic coordination of Eu 3+ ions with multidentate ligands, like iminodiacetate (IDA) and dipicolylamine (DPA). − The dynamic coordination in polymer hydrogels and elastomers allowed reversible formation/disruption of polymer networks along with tunable fluorochromic properties in response to various stimuli, including metal ions, pH, humidity, temperature, sonication, and force. Given such multistimuli responsiveness of dynamic coordination of lanthanides, we extend our design to create inhomogeneity, thus triggering the 2D-to-3D shape transformation in the interpenetrated polymer networks (Figure a).…”
