4,4'-((4-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)azanediyl)dibenzaldehyde (CAS number 2009169-65-5 ), has a triphenylamine core featuring a pinacolborane and two aldehyde groups. The pinacolborane group enables the Suzuki coupling reaction while the aldehyde groups can undergo aldol reaction and amination reaction. 4,4'-((4-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)azanediyl)dibenzaldehyde is employed to synthesise aggregation-induced emission molecules (TPA-AN-TPM). In the synthesis, 4,4'-((4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)azanediyl)dibenzaldehyde acts as a linker for connecting dimethylpyranyldene-malononitrile and anthracenes. The resulting molecule forms ultrabright red AIE dots with absolute quantum yield of 12.9%.

4,4'-((4-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)azanediyl)dibenzaldehyde is also utilised in the preparation of dyes with thiazole. This triphenylamine linked bisthiazole based dye is applied in dye-sensitised solar cells (DSSCs), displaying current density of 13.60 mA/cm-2, fill factor of 58.2%, open-circuit voltage of 620 mV and power conversion efficiency (PCE) of 4.94%.
