“…[21][22][23][24] Currently, the core skeletons of AIE materials that have been extensively studied mainly include hexaphenylsiloles (HPS), tetraphenylethylenes (TPE), and 9,10-distyrylanthracenes (DSA). They are widely used in different fields, such as stimulus response materials (mechanofluorochromic materials, [25][26][27][28][29] photochromic materials, 30 thermochromic materials 31 ), biological imaging (organelle location 32,33 ), chemical sensing (ion detection, [34][35][36][37][38] explosive detection 39 ), and OLEDs. 40 Anthracene is one of the earliest materials used in OLEDs, but anthracene is a typical fluorescent material affected by the ACQ effect, and research based on overcoming the difficulty of ACQ for anthracene has never stopped.…”

“…Nowadays, VOC detection by AIE effect is always performed with the fluorescence (FL) method. , Since Lv’s team used gold nanoclusters (AuNCs) as chemiluminescence (CL) resonance energy transfer (CRET) acceptors to significantly enhance the CL of the bis(2,4,6-trichlorophenyl)oxalate (TCPO)-H 2 O 2 system, there have been some reports on aggregation-induced chemiluminescence emission (AICE). − As the CL method has advantages of simple device, high sensitivity, wide calibration range, and low background, AICE has been used for deep-tissue singlet oxygen ( 1 O 2 ) imaging, superoxide radical anion (O 2 •– ) monitoring, Hg 2+ and CN – detection, and H 2 O 2 tracking and sensing . However, H 2 O 2 has always been needed as the oxidant in the TCPO or bis(2,4,5-trichloro-6-carbopentoxyphenyl)oxalate (CPPO) CL system, and there has been no report on AICE being triggered without an extra oxidant.…”

Volatile formaldehyde (FA) in exhaled breath (EB) is considered as a biomarker for lung cancer (LC). On-the-spot selective and sensitive detection of gaseous FA is rather important for LC screening and diagnosis. Herein, a tetrakis(4-pyridylphenyl)ethylene (Py-TPE)-based zinc metal–organic framework (MOF) with excellent aggregation-induced emission (AIE) property was utilized for absorption and selective detection of FA in EB. The porous Zn-Py-TPE served as a gaseous confinement cavity for the adsorption of FA in EB. Interestingly, Zn-Py-TPE was aggregated on paper, and then aggregation-induced chemiluminescence (CL) emission can be triggered by only adding bis(2,4,6-trichlorophenyl)oxalate (TCPO). Though without H2O2, the CL of Zn-Py-TPE-TCPO was enhanced greatly by FA. FA promoted the aggregation of Zn-Py-TPE on paper by forming halogen bonding between FA and Zn-Py-TPE, which contributed to the better selectivity. FA can also stimulate the production of more singlet oxygen (1O2) in the Zn-Py-TPE-TCPO CL system. Hence, FA could be detected via the proposed Zn-Py-TPE-TCPO system with a quantification linear range of 1.0–100.0 ppb and detection limit of 0.3 ppb. This portable, low-cost, and sensitive paper-based platform can achieve trace FA detection in EB and is expected to provide an on-the-spot screening platform for lung cancer.

“…are usually employed as the activators, leading to chemiexcitation. − However, the concentration of such fluorescent dyes is limited due to the aggregation-caused quenching (ACQ) effect at high concentrations . To break the concentration limit, aggregation-induced emission (AIE) molecules − were chosen as a substitute for ACQ dyes during fluorescence sensing. In contrast to ACQ dyes, AIE molecules/nanoparticles are nonemissive in diluted solutions but are induced to emit intensely when they aggregate in concentrated solutions through the restriction of intramolecular rotation. − Due to breaking of the concentration limit, the fluorescence quantum yields of AIE molecules can be 2 orders of magnitude higher than those of traditional ACQ molecules .…”

Aggregation-induced emission (AIE) molecules that can avoid the aggregation-caused quenching (ACQ) effect and break the concentration limit have been widely used for biosensing. Similar to fluorescence dyes, AIE molecules can be chemiexcited simply by a peroxyoxalate-based chemiluminescence (CL) reaction, but the hydrolysis of peroxyoxalate is often a problem in an aqueous solution. Herein, we report an AIE effect within peroxyoxalate-loaded silica nanoparticles (PMSNs) for an efficient harvest of CL energy as well as alleviation of bis(2,4,5-trichloro-6-carbopentoxyphenyl) oxalate (CPPO) hydrolysis. Peroxyoxalate (i.e., CPPO) and AIE molecules (i.e., 1,2-benzothiazol-2triphenylamino acrylonitrile, BTPA) were loaded together within the mesoporous silica nanoparticles (MSNs) to synthesize the BTPA-PMSN nanocomposite. The BTPA-PMSNs not only allowed CPPO to be dispersed well in an aqueous solution but also avoided the hydrolysis of CPPO. Meanwhile, the proximity between BTPA and CPPO molecules in the mesopores of MSNs facilitated the BTPA aggregate to harvest the energy from CL intermediates. Hence, the CL system of BTPA-PMSNs can work efficiently in aqueous solutions at a physiological pH. The CL quantum yield of the BTPA-PMSN system was measured to be 9.91 × 10 −5 , about 20 000-fold higher than that obtained in the rhodamine B (RhB, a typical ACQ dye)-PMSN system. Using BTPA-PMSNs for H 2 O 2 sensing, a limit of detection (LOD) as low as 5 nM can be achieved, 1000-fold lower than that achieved in the RhB-PMSNs system. Due to the feasibility of working at a physiological pH, this CL system is also quite suitable for the detection of oxidase substrates such as glucose and cholesterol. This BTPA-PMSN CL system with the merits of high CL quantum yield at a physiological pH is appealing for biosensing.
