N n dimethylacrylamide

N,N-dimethylacrylamide (DMAA, 99%), α-cyclodextrins (α-CD, 98%), β-cyclodextrins (β-CD, 98%), γ-cyclodextrins (γ-CD, 98%) and 1-pyrenebutyric acid (PyBA, 97%) were purchased from J&K Scientific Co., Ltd. (Shanghai, China). Azobisisobutyronitrile (AIBN) was purchased from Tianjin Bodi Chemical Co., Ltd. (Tianjin, China) and purified by recrystallization from ethanol. 2-Hydroxyethyl methacrylate (HEMA, 99%) was purchased from Shanghai Aladdin Chemical Reagent Co., Ltd. (Shanghai, China). Dicyclohexylcarbodiimide (DCC) and 4-dimethylaminopyridine (DMAP) were purchased from Sinopharm Chemical Reagent Co., Ltd. (Beijing, China). Tetrahydrofuran (THF), dichloromethane, diethyl ether and ethanol were used as received from commercial sources. All other reagents were used without further purification.

N,N-Dimethylacrylamide (DMA, 99%) and 2,3,4,5,6-pentafluoroStyrene (PFS, 97%) were purchased from J&K Scientific. 2,2′-Azobis(2-methylpropionitrile) (AIBN, 99%) was purchased from Sigma-Aldrich. Styrene (St, AR), potassium phosphate tribasic trihydrate (K₃PO₄^.3H₂O, AR), dichloromethane (DCM, AR), ethanol (AR), N,N-dimethylformamide (DMF, AR), toluene (AR), tetrahydrofuran (THF, AR), 1,4-dioxane (AR), and acetone (AR) were obtained from Sinopharm Chemical Reagent. Ethanethiol (98%), carbon disulfide (99%), and methyl 2-bromopropionate (98%) were purchased from Energy Chemical. AIBN was recrystallized from ethanol prior to use. All monomers were purified by passing through an alkaline aluminum oxide column to remove the inhibitor. Other reagents were used without further purification.
