Abstract ：
Circularly polarized luminescence (CPL) materials with delayed fluorescence have attracted much attention due to their ability to efficiently trap triplet state excitons, thereby improving the photoluminescence quantum yields of CPL materials. However, much effort has been normally focused on the utilization of T-1 excitons but seldom on the utilization of higher excited triplet state T-n (n > 1) excitons. Rational manipulation of higher excited triplet state T-n (n > 1) excitons and suppression of Kasha's rule of CPL materials remains a major challenge. Herein, two gold complex enantiomers ((R/S)-BPAuBC) based on axially chiral binaphthyls and 3,6-Di-tert-butylcarbazole groups are synthesized and systematically investigated. These materials exhibit aggregation-induced circularly polarized delayed fluorescence. Circularly polarized delayed fluorescence was found to be enabled by activating high-level reverse intersystem crossing (hRISC). The anti-Kasha phosphorescence at 77 K proves that the exciton has a large population in the high-lying triplet state T-2, which allows the effective hRISC process to cross back to the singlet state S-1 and emit delayed fluorescence. In addition, CPL "on-off" switching is further achieved in nanoparticles by acid-base stimulus, showing its potential as an acid-base responsive material.

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 ：
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 ：
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 ：
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.
