Overview of Irreversible Light-Responsive Micelles and Their Cleavage Mechanism

Micelle composition Photolabile group Light source Cleavage mechanism
PEG-PPyMA 1-pyrenylmethyl UV Pyrenylmethyl ester is cleaved: PPyMA → PMA + 1-pyrenemethanol (167,177)
PEG-b-PNBMA 2-nitrobenzylmethyl UV/NIR PNBMA → PMA + 2-nitrosobenzoldeyde (167)
PEG-b-P(MA-DEACM) DEACM UV/NIR Cleavage DEACM (178)
n/a 3,5-DMB UV Cleavage ester of 3,5-DMB (179)

PPyMA poly(1-pyrenylmethyl methacrylate); PMA poly(methacrylic acid); PNBMA poly(2-nitrobenzylmethyl methacrylate); DEACM coumarin chromophore (7-[diethylamino]coumarin-4-yl)methyl; 3,5-DMB 3,5-dimethoxybenzoin; n/a not applicable.
