Covalent Organic Frameworks (COFs) Triazine Ligand

A trigonal boronic acid bridging ligand linker for covalent polymeric frameworks (CPFs) in application of sensors in the field of flexible and wearable electronics, and ciprofloxacin (CFX) detection


((1,3,5-Triazine-2,4,6-triyl)tris(benzene-4,1-diyl))triboronic acid (TPBATRz) has a structure of triazine (Trz) core with three 4-phenylboronic acid anchoring groups attached at 1,3,5-positions. The boronic acid groups could help to extend the structure via Suzuki coupling reaction to form covalent polymeric frameworks (CPFs). The aromatic dendrimer structures bearing 2,4,6-triphenyl-1,3,5-triazine skeleton as the core features improved thermal stability and photophysical properties associated with improved electron-transfer processes toward the fabrication of OLEDs, OFETs and sensors.

Consisted of a triphenyltriazine core with three peripheral 3-hexylthiophene units, donor–acceptor (D–A) covalent polymeric framework CPF1 exhibited a fast switching time of 5.1 s for colouring and 8.6 s for bleaching with a high coloration efficiency of 163.7 cm2 C−1 and high optical contrast of 36% with a negligible loss of optical contrast over 150 cycles. Sensor based on CPF1 also exhibited high sensitivity, fast response time, and good stability for sensing pressure. The pressure sensor displayed an enhanced sensitivity of ∼2.92 kPa−1 with the durability of ∼2500 cycles.
