AbstractThe light fantastic: Two new 2‐(benzo[b]thiophene‐3‐yl)pyrroles have been synthesized, and are shown to exhibit optical properties that are promising for optoelectronic materials and devices such as highly efficient fluorescent sensors (see scheme). In addition a new BODIPY fluorophore, derived from 2‐(benzo[b]thiophene‐3‐yl)pyrrole, was also isolated and shows good spectroscopic properties in solution which are fully preserved in the solid state.magnified image2‐(Benzo[b]thiophene‐3‐yl)‐1‐vinylpyrrole has been synthesized directly from 3‐acetylbenzo[b]thiophene oxime and acetylene (flow system, KOH‐DMSO, 120 °C, 5 h) in 68 % yield. Devinylation of the synthesized pyrrole (Hg(OAc)2, NaBH4, 50 °C) led to the corresponding 2‐(benzo[b]thiophene‐3‐yl)pyrrole in 63 % yield. Trifluoroacetylation of both the pyrroles with trifluoroacetic anhydride (80 °C, 1 h) gave the corresponding 5‐trifluoroacetyl pyrroles in 97 % and 76 % yields, respectively. 2‐(Benzo[b]thiophene‐3‐yl)pyrrole was reacted subsequently with mesityl aldehyde, 2,3‐dichloro‐5,6‐dicyano‐1,4‐benzoquinone (DDQ), and BF3⋅OEt2 to afford 4,4‐difluoro‐3,5‐di(benzo[b]thiophene‐3‐yl)‐8‐mesityl‐4‐bora‐3a,4a‐diaza‐s‐indacene, a representative of the novel BODIPY fluorophore family (BODIPY=4,4‐difluoro‐4‐bora‐3a,4a‐diaza‐s‐indacene), in 34 % overall yield. The synthesized pyrroles exhibit promising optical properties (absorption and emission spectra, nonlinear optical (NLO) features), superior to existing analogues. The BODIPY fluorophore displays an intense red‐shifted fluorescence emission in CH2Cl2 (625 nm, 0.84 fluorescence quantum yield) that is fully preserved in the solid state.
Synthesis and Properties of (Triptycenedicarboxylatio)zinc Coordination Networks

Published: April 2009

AbstractPaddle wheels and pillars: Layered 3D metal–organic frameworks comprised of paddle‐wheel coordination units are constructed under a variety of conditions to incorporate bridging ligands (as illustrated) that impart desired properties, such as guest‐exchange behavior, luminescence, microporosity, and stability, to the material.magnified image(Triptycenedicarboxylato)zinc metal–organic frameworks (MOFs) based on paddle wheel secondary building units (SBUs) with different axial ligands have been prepared. The reproducible formation of the layered paddle‐wheel structures from triptycenedicarboxylic acid (H2TDC) and zinc nitrate under various conditions seems to be characteristic of this acid and is utilized for the construction of 3D frameworks by a pillaring approach. We attempted to bring additional functionalities into MOFs by employing the appropriate pillaring ligands, for example, bis(4‐pyridyl)‐s‐tetrazine and bis(4‐pyridyl)‐dimethoxy‐p‐phenylenedivinylene, and investigated certain properties of some MOF materials, such as guest‐exchange behavior, luminescence, microporosity, and stability.

Published: April 2009

AbstractFor controlled release and targeted delivery of curcumin in an aqueous medium a method of encapsulating curcumin and magnetic nanoparticles inside porous silica matrix has been developed. Curcumin and superparamagnetic nanoparticles are loaded inside porous silica in a single process. The graphic shows the TEM image of microtomed sample of Fe3O4 particles surrounded by a silica matrix.magnified image
Adaptation and Optical Signal Generation in a Constitutional Dynamic Network
Authors: Ulrich Sébastien , Lehn Jean‐Marie 
Published: April 2009

AbstractSelf‐sorting dynamic library: The effector‐induced modulation of the shape and constitution of the members of a constitutional dynamic network (see scheme) allows for the regulation of the interconnected constituents and for the control of an emergent function, here the generation of an optical output which originates from a charge‐transfer interaction.magnified image
Palladium(0)‐Catalyzed Cross‐Coupling of Potassium (Z)‐2‐Chloroalk‐1‐enyl Trifluoroborates: A Chemo‐ and Stereoselective Access to (Z)‐Chloroolefins and Trisubstituted Alkenes
Authors: Guinchard Xavier , Bugaut Xavier , Cook Cyril , Roulland Emmanuel 
Published: April 2009

AbstractOriginal and ambivalent: We describe the preparation of a series of new potassium trifluoroborates1, and the study of their behaviour in a Pd0‐catalyzed cross‐coupling reaction. We found that compounds1are endowed with original properties as they behave as nucleophilic cross‐coupling partners chemoselectively, but also as ambivalent synthons. The usefulness of this methodology has been successfully illustrated by the first total synthesis of anN‐acyl spermidine.magnified imageWe describe the preparation of a series of new potassium trifluoroborates1and the study of their behaviour in a Pd0‐catalyzed cross‐coupling reaction.
