Abstract ：
Luminescent supramolecular metallacycles have attractedgreat interestas a new promising class of sensing substrates. In this work, twotetraphenylethene (TPE)-based diimidazole and dipyrazole ligands withthe aggregation-induced emission (AIE) feature were designed for theconstruction of supramolecular tetragonal metallacycles 1-4 with two 90 & DEG; mononuclear [(bpy)M](2+) or dinuclear [(bpy)(2)M-2](4+) acceptors (bpy = 2,2 & PRIME;-dipyridine; M = Pd, Pt), in which thefluorescence can be quenched to an "off" state due tothe ligand-to-metal charge transfer (LMCT). Metallacycle 1 was utilized as a fluorescence sensor for phosphate (PO4 (3-)) detection in aqueous solution by means of disassembly,leading to the release of the ligand. Additionally, the metallacyclecan be regenerated through self-assembly via the introduction of Pd(II)acceptors. PO4 (3-) was detected using TPE-basedmetallacycles over a wide concentration range, with a detection limitas low as 2.1 x 10(-8) M. Furthermore, sensor 1 also presented the semiquantitative visual detection abilityfor PO4 (3-) in the test paper mode viafluorescence changes. The aforementioned studies not only enhancethe current research on fluorescent materials but also offer a strategyfor the creation of stimuli-responsive supramolecular coordinationcomplexes.

Abstract ：
Thepalladium(II)-based square structures [M8L4 ]( 8+ ) have been synthesizedby coordinating the aromatic bispyrazole ligands with dipalladiumcorners in aqueous solution via the metal-driven self-assembly, whichcan be used for efficient capture of iodine. Square-like metallamacrocyclic palladium(II) complexes[M8L4 ]( 8+ ) (1-7) were synthesized by reacting aromaticdipyrazole ligands (H2L1-H2L3 with pyromelliticarylimide-, 1,4,5,8-naphthalenetetracarboxylic arylimide-, and anthracene-basedaromatic groups, respectively) with dipalladium corners ([(bpy)(2)Pd-2(NO3)(2)](NO3)(2), [(dmbpy)(2)Pd-2(NO3)(2)](NO3)(2), or [(phen)(2)Pd-2(NO3)(2)](NO3)(2),where bpy = 2,2 '-bipyridine, dmbpy = 4,4 '-dimethyl-2,2 '-bipyridine,and phen = 1,10-phenanthroline) in aqueous solutions via metal-directedself-assembly. Metallamacrocycles 1-7 were fullycharacterized by H-1 and C-13 nuclear magneticresonance spectroscopy and electrospray ionization mass spectrometry,and the square structure of 7 center dot 8NO(3) (-) was further confirmed via single crystal X-ray diffraction.These square-like metallamacrocycles exhibit effective performancefor iodine adsorption.

Abstract ：
Owing to their structural designability and tuneable properties, supramolecular metal-organic complexes have recently emerged as promising candidates for the sensing and detection of molecules and anions. Herein, we synthesised three tripyrazolate-linked [M6L2] metallocages with the formulas [(bpyPd)(6)L-2](NO3)(6) (1), [(dmbpyPd)(6)L-2](NO3)(6) (2), and [(phenPd)(6)L-2](NO3)(6) (3) (H3L = tris(4-(5-(trifluoromethyl)-1H-pyrazol-3-yl)phenyl)amine, bpy = 2,2'-bipyridine, dmbpy = 4,4'-dimethylbipyridine, phen = 1,10-phenanthroline). Crystallography revealed that metal-directed coordination and the bidentate chelate behaviour of the ligand induced the self-assembly of supramolecular metal-organic cages. Notably, these cages were employed as turn-on fluorescence sensors for SO2 and its derivative (HSO3-) through a disassembly mechanism. Cages 1, 2, and 3 showed a highly selective and sensitive detection of HSO3- over other common anions in aqueous solutions and of SO2 gas over other common gasses, with an excellent anti-interference ability. These metallocages were subsequently applied as sensors in environmental and biological samples. This study not only enriches the ongoing research on metal-organic supramolecular materials but also facilitates the future preparation of stimuli-responsive supramolecular coordination complexes.

Abstract ：
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.

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.

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.

Abstract ：
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.
