Bis(4-nitrophenyl) phosphate 

Bis(4-nitrophenyl) phosphate is a catalyst for metal micelles and can catalyze the hydrolysis of (4-nitrophenyl) phosphate. Bis(4-nitrophenyl) phosphate is also an effective catalyst for ring-opening polymerization (ROP), which can achieve controlled polymerization of β-butyrolactone (β-BL) ring-opening and can be used to prepare diembedded polymers without quenching. segment copolymer^[1][2][3].
