The present invention relates to functionalized molecular sieves that are useful as shape-selective adsorbents and catalysts. The inventive molecular sieves have a crystalline framework and include micropores of substantially uniform size and shape formed therein. These micropores contain one or more accessible organic moieties that are linked to the crystalline framework by a carbon-silicon ond. Shape selectivity of the inventive molecular sieves may be modulated by varying the size and shape of the micropores (which is a function of the particular molecular sieve being synthesized) and the organic moiety incoporated therein. In preferred embodiments, the molecular sieves of the present invention include crosslinked monomers of the formulawherein:X is a subsituted or unsubstituted moiety andR1 and R2 are each independently either oxygen, or a substituted or unsubstituted moiey, wherein the moiety is selected from the group consisting of C1-C20 alkyl, C2-C10 alkenyl, C2-C20 alkynyl, cycloalkyl, cycloalkenyl, aryl, and heteroaryl, each optionally substituted with one or more substituents elected from the group consisting of C1-C5 alkyl, C2-C5 alkenyl, C2-C5 alkynyl, cycloalkyl, cycloalkenyl, aryl, heteroaryl, and a functional group. Because the molecular sieve framework is generally robust to a variety of synthetic conditions, the incorporated organic moieties may be further functionalized with standard protocols in most cases.
