Overview | Product Information | MSDS | Related Products

2,5-Bis(allyloxy)terephthalohydrazide (CAS number 2227151-69-9) is a benzene building block substituted with two allyloxy groups and two hydrazides. The hydrazide groups in 2,5-bis(allyloxy)terephthalohydrazide react with aldehyde derivatives to form COFs with hydrazone linkages. The allyloxy groups allow the resulting COFs to be further functionalized with alkene such as poly(ethylene glycol) methyl ether methacrylate (PEGMA), via radical polymerization. The COF-PEGMA is applied as a solid-state electrolyte for lithium batteries, exhibiting high ionic conductivity of 5.3 × 10⁻⁵ S/cm and lithium ion transference number of 0.47.

The allyloxy pendant groups in COFs can function as Hg²⁺ acceptors. Additionally, the binding of Hg²⁺ quenches the fluorescence of the COFs. Thus, they are used for selective mercury ion detection in applications of water purification.
