Figure 1: TPE-CS samples in the form of powder solution and hydrogel.

From: Gelation process visualized by aggregation-induced emission fluorogens

Figure 1

(a) Molecular structure of TPE-CS. (b) Digital images of powder samples; Scale bar, 1.0 cm. (c) TPE-CS samples after treated by freeze-thaw dissolving procedure in LiOH-urea aqueous solution; Scale bar, 1.0 cm. (d) Photoluminescence spectra of TPE-CS solution, the intensity corresponding to sample C was denoted as zero, since sample C cannot be dissolved in the LiOH-urea solvent. (e) Digital images of formation of hydrogel with TPE-CS: solution of TPE-CS, TPE-CS gel after thermal gelation, and TPE-CS hydrogel after complete removal of LiOH and urea; Scale bar, 5.0 mm. The fluorescent photographs were taken under ultraviolet illumination (365 nm).
