A Neutral Naphthalene Diimide [2]Rotaxane
Jacquot de Rouville, Henri-Pierre,Iehl, Julien,Bruns, Carson J.,McGrier, Psaras L.,Frasconi, Marco,Sarjeant, Amy A.,Stoddart, J. Fraser American Chemical Society 2012 ORGANIC LETTERS Vol.14 No.20
<P>A neutral donor–acceptor [2]rotaxane, which has been synthesized using click chemistry, has had its solid-state structure and superstructure elucidated by X-ray crystallography. Both dynamic <SUP>1</SUP>H NMR spectroscopy and electrochemical investigations have been employed in an attempt to shed light on both geometrical reorganization and redox-switching processes that are occurring or can be induced within the [2]rotaxane.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/orlef7/2012/orlef7.2012.14.issue-20/ol3022963/production/images/medium/ol-2012-022963_0006.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/ol3022963'>ACS Electronic Supporting Info</A></P>

Synthesis, Structure, and Metalation of Two New Highly Porous Zirconium Metal–Organic Frameworks
Morris, William,Volosskiy, Boris,Demir, Selcuk,Gá,ndara, Felipe,McGrier, Psaras L.,Furukawa, Hiroyasu,Cascio, Duilio,Stoddart, J. Fraser,Yaghi, Omar M. American Chemical Society 2012 Inorganic Chemistry Vol.51 No.12
<P>Three new metal–organic frameworks [MOF-525, Zr<SUB>6</SUB>O<SUB>4</SUB>(OH)<SUB>4</SUB>(TCPP-H<SUB>2</SUB>)<SUB>3</SUB>; MOF-535, Zr<SUB>6</SUB>O<SUB>4</SUB>(OH)<SUB>4</SUB>(XF)<SUB>3</SUB>; MOF-545, Zr<SUB>6</SUB>O<SUB>8</SUB>(H<SUB>2</SUB>O)<SUB>8</SUB>(TCPP-H<SUB>2</SUB>)<SUB>2</SUB>, where porphyrin H<SUB>4</SUB>-TCPP-H<SUB>2</SUB> = (C<SUB>48</SUB>H<SUB>24</SUB>O<SUB>8</SUB>N<SUB>4</SUB>) and cruciform H<SUB>4</SUB>-XF = (C<SUB>42</SUB>O<SUB>8</SUB>H<SUB>22</SUB>)] based on two new topologies, <B>ftw</B> and <B>csq</B>, have been synthesized and structurally characterized. MOF-525 and -535 are composed of Zr<SUB>6</SUB>O<SUB>4</SUB>(OH)<SUB>4</SUB> cuboctahedral units linked by either porphyrin (MOF-525) or cruciform (MOF-535). Another zirconium-containing unit, Zr<SUB>6</SUB>O<SUB>8</SUB>(H<SUB>2</SUB>O)<SUB>8</SUB>, is linked by porphyrin to give the MOF-545 structure. The structure of MOF-525 was obtained by analysis of powder X-ray diffraction data. The structures of MOF-535 and -545 were resolved from synchrotron single-crystal data. MOF-525, -535, and -545 have Brunauer–Emmett–Teller surface areas of 2620, 1120, and 2260 m<SUP>2</SUP>/g, respectively. In addition to their large surface areas, both porphyrin-containing MOFs are exceptionally chemically stable, maintaining their structures under aqueous and organic conditions. MOF-525 and -545 were metalated with iron(III) and copper(II) to yield the metalated analogues without losing their high surface area and chemical stability.</P><P>Within this paper, three new metal−organic frameworks are synthesized and structurally characterized, MOF-525, -535, and -545, based on two new topologies, <B>ftw</B> and <B>csq</B>. MOF-525 has the highest Brunauer−Emmett−Teller surface area and MOF-545 has the largest pores of any zirconium-based MOF, 2620 m<SUP>2</SUP>/g and 36 Å, respectively. Most importantly, MOF-525 and -545 contain porphyrin sites, which are metalated with copper(II) and iron(III).</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/inocaj/2012/inocaj.2012.51.issue-12/ic300825s/production/images/medium/ic-2012-00825s_0002.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/ic300825s'>ACS Electronic Supporting Info</A></P>
