摘要：A polar functionalized polymer modified porous substrate for solid phaseextraction or chromatography, comprising a porous substrate and a polar functionalizedpolymeric monolith formed thereon, wherein the polymeric monolith comprises L-A-Pand L-Q-R—Pand optional L-A-L-Q-R units, wherein A is a Cmonocyclic or bicyclic aryl orheteroaryl, and Q is —NRC(O)—, —C(O)NR—, —OC(O)NR—, —OC(O)R—, —NRC(O)O—, —NRC(O)NR—, —NCO, —CHOHCHOH—, CHOCHCHO—, —(CHCHO)—, —(CHCHCHO)—, —C(O)—, —C(O)O—, —CHC(O)CH—, —S—, —SS—, —CHOH—, —O—, —SO—, —SO—, —SO—, —OSO, —SONR—, —NR—, and —NR—, —CN, —NC, —CHOCH—, —NHC(NH)NH—, —NO, —NO, —OPO—, —OH; r is 0 or 1; and R is hydrogen, Cmonocyclic or bicyclic aryl orheteroaryl, Cbranched, unbranched, or cyclic hydrocarbyl; L is a bond or a Cbranched,unbranched, or cyclic hydrocarbyl. Methods of preparing and using the polymer modifiedporous substrates are disclosed.
