<P>This work reports the synthesis and application of metal–organic framework (MOF)@microporous organic network (MON) hybrid materials. Coating a MOF, UiO-66-NH<SUB>2</SUB>, with MONs forms hybrid microporous materials with hydrophobic surfaces. The original UiO-66-NH<SUB>2</SUB> shows good wettability in water. In comparison, the MOF@MON hybrid materials float on water and show excellent performance for adsorption of a model organic compound, toluene, in water. Chemical etching of the MOF results in the formation of hollow MON materials.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jacsat/2014/jacsat.2014.136.issue-19/ja500362w/production/images/medium/ja-2014-00362w_0006.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/ja500362w'>ACS Electronic Supporting Info</A></P>

<P>This work reports on the controllable guest entrapment and release behavior of microporous organic hollow spheres (MOHs). Porphyrins which are soluble in both water and methanol were entrapped in the MOHs using methanol solution. The water-soluble porphyrins entrapped in MOHs were not extracted by water due to the hydrophobicity of microporous organic shells. In contrast, the porphyrins were released gradually into aqueous solution by adding water-soluble organic solvents. The release behavior depended on the kind of organic solvents used and on the alkyl chain length of the porphyrin compounds. These properties were applied for the fluorescent alert towards the existence of organic solvents in flowing aqueous media.</P> <P>Graphic Abstract</P><P>Water soluble porphyrins were entrapped in microporous organic hollow spheres (MOHs).

<P>This work shows that hollow and microporous organic polymers (H-MOPs) are good templating materials for the synthesis of inorganic material-carbon nanocomposites. The precursor compound, (NH4)2MoS4, was incorporated into H-MOPs. Heat treatment under argon resulted in the formation of hollow MoS2-carbon nanocomposites (MSC). According to microscopic analysis, the MoS2 in the MSC has a layered structure with an elongated interlayer distance. The MSC showed high reversible discharge capacities up to 802 mA h g(-1) after 30 cycles and excellent rate performance for lithium ion batteries. The promising electrochemical performance of the MSC is attributed to the very thin and disordered nature of MoS2 in the carbon skeleton. The role of chemical components of the MSC in the electrochemical process was suggested.</P>
