BODIPY based self-healing fluorescent gel formation via acylhydrazone linkage

Polymeric BODIPY derivatives with reactive functional groups undergo reversible formation of covalent bonds leading to self-healing properties. Cross-reactivity of acyl-hydrazine and aldehyde moieties forms the basis of dynamic covalent chemistry leading to sol-gel transition in this series of compounds. In addition, thin layers of absorbers show efficient energy transfer indicating a potential in solar concentration.
