“…These multifunctioning materials can be applied as sensors for pH [33,34], transition metals [17], temperature and smart materials [34][35][36][37][38] and even low-cost antibacterial polymers for biomedical and food packaging [39]. Given the diverse implementation of dansyl derivatives into multifunctional solid materials [31,[40][41][42], and our recent knowledge on bis-dansyl derivatives bearing a disulfide bridge [43], the three dansyl derivatives L1, L2 and L3 bearing single sulfur bridges were synthesized and fully characterized. Above mentioned ligands were designed in order to demonstrate good complexation ability toward heavy metals.…”
