Overview
Related Products

Tris(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)amine (TPA-3BO), CAS number 267221-90-9, is a triphenylamine with a boronic acid pinacol ester on the end of each benzene rings. The boronic acid pinacol ester functional groups are ideal for Suzuki cross-coupling reaction to extend the size of the structure. Triarylamine (TAA) derivatives are good electrode materials for their high charge mobilities, excellent thermal stabilities, and high redox activity. Polytriarylamines (PTAAs) allow reversible radical redox reactions to occur through charge/discharge.

Porous aromatic frameworks (PAFs) LNU-58, prepared through Suzuki cross-coupling polymerization of TPA-3BO and 3,5-dibromoazobenzene, can adsorb iodine effectively with an adsorption capacity of 3533.11 mg g^-1 (353 wt%) for gaseous iodine, and 903.6 mg g^-1 (90 wt%) for dissolved iodine, among the highest level among all porous adsorbents.

Conjugated microporous polymer (CMP) TPA-TAB, with a large BET surface area (490 m² g ^-1), demonstrated great thermal stability while being employed as electrode materials in supercapacitor devices. The TPA-TAB CMP showed an outstanding specific capacitance (684 F g ^-1 at 0.5 A g ^-1) and long-term stability with a capacitance retention of 99.5% after 5000 cycles (at 10 A g ^-1) in a three-electrode supercapacitor system.
