The Ca-MOF FIR-29 is synthesized and exhibits a honeycomb lattice of hexagonal channels with an aperture of ?16 A, giving a BET surface area of 2061 m2 g?1. The consecutive slipped pi···pi stacking interactions of photoactive tris((4-carboxyl)phenylduryl)amine (TCPA) groups on the surface of hexagonal channels makes it an effective photocatalyst for catalyzing the typical Mannich photocatalysis, forming beta-tetrahydroisoquinolne ketones in high isolated yields. Catalytic activity for FIR-29 is about 2.7 times enhancement over that for mesoporous DUT-63 consisted of discrete TCPA groups without any intermolecular interaction. This is mainly due to the fact that the rigid compact stacking of tri([1,1?-biphenyl]-4-yl)amine (TBPA) is conducive to form stable TBPA radical, and is optimal for electron or energy transfer to expedite the reactivity of sp3 carbon atoms and allow higher photocatalytic conversion.

Covalent organic frameworks (COFs) emerging as a novel kind of visible light-responsive organic semiconductor have attracted extensive research attention in the field of photocatalytic organic transformations. However, the key parameters affecting their photocatalytic properties are still not clear. In this work, a series of [3 + 3] COFs with similar two-dimensional hexagonal structure but different compositions are synthesized and employed as model materials for investigating the key factors affecting the photocatalytic properties in the visible-light-driven reductive dehalogenation reaction and the aerobic cross-dehydrogenative coupling reaction. In comparison with -H and -CF3, the -OH substituent in the aromatic ring could narrow the band gap of the COFs. The COFs with a triazine skeleton in the framework usually boost the photocatalytic activity, possibly because of the enhanced charge separation efficiency by the formation of a donor-acceptor domain. As a combined result of the narrow band gap, efficient charge separation, and high conductivity, the COF possessing both a -OH group and triazine skeleton shows the highest activity in the photocatalytic reductive dehalogenation reaction. Notably, COFs could be easily recovered and reused several times without the loss of crystallinity. Our primary results may shed light on the design of efficient COF-based semiconductors for photocatalytic organic transformations.

Direct oxidation of alpha-CH2 group of free amines is hard to achieve due to the higher reactivity of amine moiety. Therefore, oxidation of amines involves the use of sophisticated metallic reagents/catalyst in the presence or absence of hazardous oxidants under sensitive reaction conditions. A novel method for direct C-H oxygenation of aliphatic amines through a metal-free activation of molecular oxygen has been developed. Both activated and unactivated free amines were oxygenated efficiently to provide a wide variety of amides (primary, secondary) and lactams under operationally simple conditions without the aid of metallic reagents and toxic oxidants. The method has been applied to the synthesis of highly functionalized amide-containing medicinal drugs, such as O-Me-alibendol and -buclosamide.

For the expansion of a rectangular cavity (RC) defined by two isonicotinic acid (isoH) dimers as bridging ligands and two SCN bridges, we conducted a structural extension based on the elongation of the bridging ligands by the replacement of isoH with longer 4-pyridyl-substituted carboxylic acid (PCA). For this purpose, the following three PCAs have been employed: trans-3-(4-pyridyl) propenoic acid (acrylH), 4-(4-pyridyl)benzoic acid (pybenH), and trans-3-(4-(4-pyridyl)phenyl)propenoic acid (pppeH). Self-assembly of Ni 2+, SCN-, and each of four PCAs involving isoH, acrylH, pybenH, and pppeH in the presence of an aromatic guest gave four inclusion compounds formulated as [Ni(SCN)2(isoH)2]·1/ 2(benz[a]anthracene) (1), [Ni(SCN)2(acrylH)2]·1/ 2(benz[a]anthracene) (2), [Ni(SCN)2(pybenH)2] ·(pyrene) (3), and [Ni(SCN)2(pppeH)2] 3/2·(benz[a]anthracene) (4). X-ray crystal structural determination of 1-4 revealed that the proposed structural extension was successful. Their crystal structures are layered structures of two-dimensional (2D) grid-type coordination frameworks (2D host layers) framed with bridging ligands of the corresponding PCA dimers and 1D chains consisting of Ni 2+ ions and mu1,3-SCN- ions. The lengths of the PCA dimers are 12.269(5) A (isoH dimer), 16.890(4) A (acrylH dimer), 20.89(2) A (pybenH dimer), 25.387(3) A (pppeH dimer A), and 25.527-(4) A (pppeH dimer B). Each 2D host layer has RCs defined by the two corresponding PCA dimers and the two SCN bridges. The dimensions of RCs are expanded in proportion to the increase in the lengths of the PCA dimers: 29.52 x 5.60-7.20 A2 (4) > 24.95 x 5.46-7.38 A2 (3) > 20.88 x 5.49-7.25 A2 (2) > 16.41 x 5.53-7.43 A2 (1). These expansions reflect the number of aromatic guests that can be included in RCs. RC of 1 include only one molecule of benz[a]anthracene, whereas RCs of 3 or 4 includes two molecules of pyrene or benz[a]anthracene, respectively. Comparison of the lengths between the PCA dimers and 4,4?-bipyridine-type ligands demonstrated that a design strategy – the preparation of a bridging ligand through self-assembly of two PCAs – is both efficient and particularly suitable for the preparation of very long bridging ligands.

Photocatalysis has been distinguished itself as one of the most promising technologies from the wide variety of renewable energy projects underway, as it represents a promising approach to realize solar energy conversion. Under light irradiation, semiconductors (TiO2, Ag3PO4, WO3, CdS, and ZnS etc.) have demonstrated great potential in photolysis of water to yield hydrogen fuel, decomposition or oxidization of hazardous substances, photoelectrochemical conversion, as well as artificial photosynthesis. However, the disadvantages of easy agglomeration, and low solar energy conversion efficiency of these inorganic catalysts limit their large scale applications. Developing new photocatalysts has been attracting great attention in the related research communities. Owing to their structural diversity and controllable synthetic procedures, coordination polymers (CPs) provide a newly emerging platform to organize light-harvesting antennae and catalytic centers to achieve solar energy conversion. Besides, controllable integration of CPs with functional materials is leading to the creation of new multifunctional composites/hybrids, which exhibit superior photocatalytic performances to those of the individual components due to the collective behavior of the functional units. In this article, the latest advances of CPs based materials in the application of photocatalysis are critically reviewed, and the main approaches for efficient light harvesting and active site engineering in CPs-based photocatalysts are discussed. The main advantages of CPs as photocatalysts and the challenges faced for further improving catalytic performance are also highlighted.

Synthesis and in vitro cytotoxicity assays of new anthranilamide MDR modulators have been performed to assess their inhibition potency of the P-glycoprotein (P-gp) transporter. The aromatic spacer group between nitrogen atoms (N1 and N2) in the known inhibitor XR9576 was replaced with a flexible alkyl chain of 2 to 6 carbon atoms in length. 6,7-Dimethoxy-1,2,3,4-tetrahydroisoquinoline and their open-chain N-methylhomoveratrylamine counterparts were shown to be potent P-gp inhibitors. The maximal inhibition was obtained when using an ethyl or propyl spacer. Several compounds were more potent than verapamil and intrinsically less cytotoxic than XR9576. In addition, in vitro metabolism studies of 23a with a subset of human CYP-450 isoforms revealed that, unlike XR9576, 23a inhibited CYP3A4, an enzyme that colocalizes with P-gp in the intestine and contributes to tumor cell chemoresistance by enhancing the biodisposition of anticancer drugs such as paclitaxel toward metabolism. In this context, 22a might be a suitable candidate for further drug development.
