Structure–Activity Relationship and Stimuli-Responsiveness Behavior of Metallosupramolecular Polymers

Figure 18

(a) A DMTA of solution-cast films with Zn²⁺ : Eu³⁺ ratios ranging from 100 : 0 to 50 : 50 is shown in the top image. Prior to testing, samples were annealed at −35°C. (b) Samples were cooled directly to −110°C at room temperature. In the middle, images of solution-cast films with different Zn²⁺ : Eu³⁺ ratios (100 : 0 to 50 : 50) show different luminescence colors between blue and red-pink under UV light (365 nm).
