Abstract:
A molecular sieve comprising a crystalline framework and micropores of substantially uniform size and shape formed therein, wherein the size of the micropore is less than or equal to 15 .ANG. and wherein the framework includes one or more monomers that are covalently bonded thereto and substantially evenly distributed therein, the monomer having the general formula ##STR11##wherein:n is an integer from 1 to 5;X is a substituted or unsubstituted moiety; andR.sup.a.sup..sub.i and R.sup.b.sup..sub.i for i=1 to i=n are each independently either oxygen, or a substituted or unsubstituted moiety, wherein the moiety is selected from the group consisting of C.sub.1 -C.sub.20 alkyl, C.sub.2 -C.sub.20 alkenyl, C.sub.2 -C.sub.20 alkynyl, cycloalkyl, cycloalkenyl, aryl, and heteroaryl, each optionally substituted with one or more substituents selected from the group consisting of C.sub.1 -C.sub.5 alkyl, C.sub.2 -C.sub.5 alkenyl, C.sub.2 -C.sub.5 alkynyl, cycloalkyl, cycloalkenyl, aryl, and heteroaryl, and a functional group selected from the group consisting of alcohol, sulfonic acid, phosphine, thiol, thioether, ketone, aldehyde, ester, ether, amine, imine, amide, imide, imido, nitro, carboxylic acid, disulfide, carbonate, isocyanate, carbodiimide, carboalkoxy, carbamate, acetal, ketal, boronate, cyano, cyanohydrin, hydrazine, oxime, hydrazide, enamine, sulfone, sulfide, sulfenyl, and halogen.
