摘要 ：
In this study, parallelogram-like macrocyclic supramolecular metallacycles [Pd-6(bpy)(6)(L-1)(4)](PF6)(8) (1a) and [Pd-6(bpy)(6)(L-2)(4)](PF6)(8) (2a), where HL1=1-(1H-pyrazole-4-yl)-4-(4-pyridyl)benzene, HL2=9-(1H-pyrazole-4-yl)-10-(4-pyridyl)anthracene,and bpy=2,2'-bipyridine, are synthesized by reacting aryl pyrazole pyridine ligands with dipalladium corners in aqueous solutions via metal-directed hierarchical self-assembly. The structures of the supramolecular Pd parallelograms are confirmed through single-crystal X-ray diffraction. Notably, the two parallelogram metallacycles can be used as"turn-on"fluorescence sensors to detect HSO3- through a disassembly mechanism. In addition, the 1a-based sensor shows selective detection of HSO3- without interference from other anions. The detection limit was as low as 0.131 mu mol center dot L-1. Furthermore, complex 1a presented the semiquantitative visual detection ability for HSO3- in the test trip mode via fluorescence changes. CCDC: 2308664, 1a; 2308665, 2a.

摘要 ：
A series of regioisomeric luminophores L1-L8 with 1H-pyrazol-3-yl or 1H-pyrazol-4-yl substituents at the different positions of anthracene core have been synthesised and characterised. According to the photophysical properties and related frontier orbital features of these compounds, the 'site-effect' of pyrazolyl substituent on an anthracene unit can be found, demonstrating the dependence of the properties of the compound on the position of substitution of the pyrazolyl moieties connecting to the anthracene core. Moreover, the target luminophores present reversible mechanochromism properties. The most significant mechanochromism luminescence is achieved for luminophores L1 and L2 with pyrazolyl substituents at the 9-and 10-positions of the anthracene unit. Upon grinding the pristine powder sample, a colour change from light yellow to yellow-green is observed. In addition, the target luminophores L2, L4, L6 and L8 demonstrate sensing properties of Hg2+ ions with high selectivity and exceptional sensitivity. These findings suggest that these anthracene-centred luminophores are promising functional platforms with fluorescence and selective heavy metal sensor arrays.

摘要 ：
A series of clip-shaped cationic molecular corners C1 similar to C4 (Cl = [(bpy)(2)Pd-2(L-1)(2)](2+), C2 = [(dmbpy)(2)Pd-2(L-1)(2)](2+), C3 = (bpy)(2)Pd-2(L-2)(2)](2+), C4 = (dmbpy)(2)Pd-2(L-2)(2)](2+), bpy = 2,2-bipyridine, dmbpy = 4,4'-dimethyl-2,2-bipyridine) were synthesized through dipalladium complexes [(bpy)(2)Pd-2(NO3)(2)](NO3)(2), [(dmbpy)(2)Pd-2(NO3)(2)](NO3)(2) and bifunctional pyrazole ligands 4-(3,4-dimethoxyphenyl)-3,5-dimethyl-1H-pyrazol (HL1) and 4,4 ''-(5-(1H-pyrazol-4-yl)-1,3-phenylene)dipyridine (HL2). Complexes C1 similar to C4 were characterized by H-1 and C-13 NMR, electrospray ionization mass spectrometry (ESI-MS), elemental analysis, and IR spectroscopy. The X-ray diffraction analysis of C1 center dot 2NO(3)(-) revealed a Pd-2 dimetallic clip-shaped structure which was synthesized by two bifunctional ligands doubly bridged by the [(bpy)Pd](2) dimetal units. Additionally, all of the complexes with NO3- as counter anions exhibited high-efficiency catalytical performance in the Suzuki-coupling reaction attributed to the tunable impact and weak dinuclear Pd(II)center dot center dot center dot Pd(II) intramolecular bonding interaction.

摘要 ：
A series of capsule-like anion receptors (1: {[(bpy)2Pd2]2L12}4+, 2: {[(bpy)2Pd2]2L22}4+, 3: {[(bpy)2Pd2]3L32}6+ and 4: {[(bpy)2Pd2]3L42}6+) have been successfully self-assembled by coordinating the flexible amide based polypyrazole ligands (H2L1: N1,N4-di(1H-pyrazol-5-yl)terephthalamide, H2L2: N1,N4-bis(3-methyl-1H-pyrazol-5yl)- terephthalamide, H3L3: N1,N3,N5-tri(1H-pyrazol-5-yl)benzene-1,3,5-tricarboxamide and H3L4: N1,N3,N5-tris (3-methyl-1H-pyrazol-5-yl)benzene-1,3,5-tricarboxamide) with dipalladium corners ([(bpy)2Pd2(NO3)2](NO3)2, where bpy = 2,2 '-bipyridine) in aqueous solution. These complexes were characterized by 1H NMR, 19F NMR, 31P NMR, 2D 1H-1H NOSEY spectra, ESI-MS and single crystal X-ray diffraction. Interestingly, the NMR spectra measured in solution and structure analysis carried out in the solid state consistently confirmed that one nitrate anion was unsymmetrically accommodated in the cavity of capsules 1 and 2 via N-Hanion hydrogen bonding and other multiple weak interactions. Furthermore, 1H NMR titrations for competitive anion exchange indicated that complexes 14NO3xa1; and 24NO3xa1; show high selectivity for the encapsulation of NO3- in dimethyl sulfoxide.

摘要 ：
Two novel bis-(beta-diketonate) ligands, 1,1 '-(anthracene-1,8-diyl)bis(butane-1,3-dione) (H2L1), 1,1 '-(anthracene1,5-diyl)bis(4,4,4-trifluorobutane-1,3-dione) (H2L2) have been designed and synthesized for self-assembly of the luminescent supramolecular coordination compounds with transition and lanthanide metals. Two neutral dinuclear supramolecular assemblies Cu(II)-bis-beta-diketonate macrocyclic complex [Cu2(L1)2](CH3OH)2 (1.2CH3OH) and Eu(III) bis-beta-diketonate triple-stranded complex [Eu2(L2)3](CH3OH)4 (2.4CH3OH) have been characterized by various spectroscopic techniques. Their photophysical properties were further investigated. Xray single crystal structural analysis revealed that complex 1.2CH3OH adopts a 1D chain arrangement which is constructed with a pitch of 1.951 angstrom through intermolecular hydrogen bonds along the b axis. The slightly distorted parallelogram of 1 is a neutral [M2L2]-type macrocycle with a size of 5.40 angstrom x 8.40 angstrom. The triple-stranded helicate CPK (Corey-Pauling-Koltun) diagram was calculated using Scigress 2.6 program.

摘要 ：
Two types of palladium(II)-based metallacalixarenes [ML](2+) and [ML2](2+) have been synthesized through coordination-driven self-assembly from a series of flexible pyridine-bridged diimidazole ligands [2,6-bis ((1H-imidazol-1-yl)methyl) pyridine (L-1), 2,6-bis((1H-benzo[d]imidazol-1-yl)methyl)pyridine (L-2), 2,6-bis((1H-naphtho[2, 3-d]imidazol-1-yl)methyl)pyridine (L-3)], with palladium(II)-based building blocks [Pd(BF4)(2)(M-1-BF4) and (tmeda)Pd(NO3)(2)(M-2-NO3) (tmeda = N,N,N',N'-tetramethyl-ethylenediamine)]. All complexes were characterized by NMR spectroscopy (H-1 NMR and C-13 NMR), mass spectrometry (CSIMS, ESI-HRMS) and elemental analysis. The single crystal X-ray diffraction analysis of [(ML22)-L-1](NO3)(2), [(ML23)-L-1](NO3)(2), [(ML23)-L-1](PF6)(2) and [(ML3)-L-2](NO3)(2) further confirmed the uniquely single bowl-shape and double bowl-shape structures. The anion binding properties within the metallacalixarenes as receptors were also investigated by NMR titration experiments in DMSO.
