Recently, ultrasensitive detection and multi-guest sensing have received extensive attention due to their high sensitivity and efficiency. Herein, we report a novel approach to achieve ultrasensitive detection of multi-analyte. This approach is concluded as “rationally introduce Aggregation-Induced Emission (AIE) into chemosensor”. According to this approach, by rationally introducing self-assembly moiety, the obtained chemosensor DNS could serve as a novel AIEgen and show strong AIE in DMSO/H2O (water fraction 80%) binary solution. Interestingly, a simple fluorescent sensor array based on the DNS has been developed. This sensor array could selectively sense Fe3+, Al3+, H2PO4 ? and L-Arg in water solution. More importantly, this sensor array shows ultrasensitive detection for Fe3+, Al3+ and L-Arg. The LODs of the sensor array for Fe3+, Al3+ and L-Arg are in the range of 3.54 × 10?9 M to 9.42 × 10?9 M. Moreover, H2PO4 ? could realize the reversible detection of Fe3+ in the DMSO/H2O (water fraction 80%) solution. Meanwhile, DNS-based test papers and thin films were prepared, which could serve as test kits for convenient detection Fe3+, Al3+, and L-Arg in water. In addition, they could also act as efficient erasable fluorescent display materials.

Light-harvesting is a key step in photosynthesis, but it is still a challenge to create an efficient artificial light harvesting system in a broader solar spectrum to mimic natural processes. Here, we have fabricated, for the first time, a highly efficient artificial light-harvesting system through directly embedding CsPbBr3quantum dots (QDs) inside a supramolecular self-assembly of thymine functionalized-pillar[5]arene (PTY) and an eosin Y-based derivative (EYB). The donor CsPbBr3QDs exhibit a broad spectral absorption in the UV-visible range, and their emission shows good spectral overlap with the absorption of EYB, thus effective excitation energy is transferred from CsPbBr3to the acceptor EYB with an energy transfer efficiency of 96.5%. Importantly, the combination displayed excellent photocatalytic activity in cross-coupling hydrogen evolution reactions, and the product yield was more than 2.5 times that obtained using eosin Y alone. Our research opens up a new avenue for utilizing perovskite QDs with broad spectral absorption as the energy donor to construct efficient light-harvesting systems for solar energy conversion.

Paragraph 0018, (2019/08/12)
The invention designs and synthesizes a naphthoyl hydrazide-functionalized organic small-molecule gelatin factor DNS. The gelatin factor can form supramolecule organogel GDNS through intermolecular hydrogen bonds, Van der Waals' force and pi-pi interaction in a DMSO/H2O solution, and the GDNS can produce yellow-green aggregation induced fluorescence. Fe, Hg, Ag, Ca, Cu, Co,Ni, Cd, Pb, Zn, Cr, Mg and other ions are dded separately to the GDNS, the fluorescence of the GDNS can be quenched by only Fe, Hg and Cu, and stable metal gel is formed; and in addition, the lowest limits of detection for the three metal ions by using GDNS are 1.00x10 M, 9.29x10 M and 1.26x10 M, so that synchronous ultra-sensitive detection of thethree metal ions is achieved.
