Construction of Interlayer Conjugated Links in 2D Covalent Organic Frameworks via Topological Polymerization

Two-dimensional covalent organic frameworks (2D COFs) are well-defined polymeric sheets that usually stack in an eclipsed mode via van der Waals forces. Extensive efforts have been made to manipulate interlayer interactions, yet there still lack a way to

Subnanometer gold clusters on amino-functionalized silica: An efficient catalyst for the synthesis of 1,3-diynes by oxidative alkyne coupling

Subnanometer (d = 0.8 ± 0.2 nm) gold particles homogeneously dispersed on amino-functionalized silica catalyze Glaser-type alkyne coupling, providing corresponding 1,3-diynes under mild conditions. Readily available λ3-iodane PhI(OAc)2 is used as an oxidant and 1,10-phenanthroline is used as an additive. Ten symmetrical 1,3-diynes and three products of heterocoupling containing various functionalities are isolated in high yields. The catalyst can be recycled at least five times, giving consistently high isolated yields and maintaining the size and distribution of gold clusters. This unique combination of stable subnanometer gold clusters and hypervalent iodine thus paves a hitherto unexplored avenue in organic synthesis employing heterogeneous gold catalysis.

Interacting networks of purely organic spin-1/2 dimers

In the present study we report the synthesis of some novel nitronyl nitroxide biradical systems 1-4c with various π-bridges between the radical centres. UV-Vis, IR, EPR and X-ray diffraction studies, along with MS and NMR data where appropriate, are described. Magnetic measurements revealed that the biradicals 1c, 3c and 4c exhibit a moderately strong antiferromagnetic intra-molecular exchange, whereas nitroxide 2c shows a significantly higher exchange coupling, which can only be explained by the presence of strong inter-molecular interactions. From DFT calculations performed on the basis of the X-ray crystal structure of compound 4c, a theoretical value of the intra-dimer coupling constant Jintra = -8.6 K is obtained. Direct proof also for inter-molecular arrangement with Jinter ～ -2 K was provided by the low temperature AC studies of biradical 4c. According to the magnetic characterization, the nitronyl biradical 4c is a promising candidate for a purely organic-based low-dimensional quantum magnet.

P-phenyleneethynylene molecular wires: Influence of structure on photoinduced electron-transfer properties

A series of donor-acceptor arrays (exTTF-oPPE-C60) containing π-conjugated oligo(phenyleneethynylene) wires (oPPE) of different length between π-extended tetrathiafulvalene (exTTF) as electron donor and fullerene (C60) as electron acceptor has been prepared by following a convergent synthesis. The key reaction in these approaches is the bromo-iodo selectivity of the Hagihara-Sonogashira reaction and the deprotecting of acetylenes with different silyl groups to afford the corresponding donor-acceptor conjugates in moderate yields. The electronic interactions between the three electroactive species were determined by using UV-visible spectroscopy and cyclic voltammetry. Our studies clearly confirm that, although the C60 units are connected to the exTTF donor through π-conjugated oPPE frameworks, no significant electronic interactions are observed in the ground state. Theoretical calculations predict how a simple exchange from C=C double bonds (i.e., oligo(p-phenylenevinylene) to C≡C triple bonds (i.e., oPPE) in the electron donor-acceptor conjugates considerably alters long-range electron transfer. Photoexcitation of exTTF-oPPE-C 60 leads to the following features: a transient photoproduct with maxima at 660 and 1000 nm, which are unambiguously attributed to the photolytically generated radical-ion-pair state, [exTTF+-oPPE- C60-]. Both charge-separation and charge-recombination processes give rise to a molecular-wire behaviour of the oPPE moiety with an attenuation factor (β) of (0.2 ±0.05) A-1.

Effect of varying the anionic component of a copper(I) catalyst on homologation of arylacetylenes to allenes by the Mannich reaction

The effect of varying the anionic component of a copper(I) catalyst in the homologation of terminal arylacetylenes to allenes by the Mannich reaction was investigated. Varying amounts of allenes, Mannich bases and dimers were obtained depending on the nature of the anionic component of the copper catalyst. On the other hand, Eglinton-Glaser dimerizations were achieved in high yields with 0.5 equiv. of triethylamine. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.

Orientation and substituent effects on the properties of the diacetylene-group connected octaethylporphyrin-dihexylbithiophene derivatives (OEP-DHBTh-X) carrying electron-withdrawing groups

Orientational isomers of the octaethylporphyrin-dihexylbithiophene (OEP-DHBTh) derivatives connected with a diacetylene linkage were synthesized, with various electron-withdrawing substituents X attached at the ends. The effects of DHBTh orientation and X substituent on the properties of OEP-DHBTh-X (X = H, Br, CN, CHO, and NO2) were studied and compared with those of related OEP derivatives.
