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.
