TL;DR: A series of colorimetric and fluorescent pH chemosensors L1∼L3, bearing acylhydrazone moiety as pH sensing site and nitrophenylfuran as signal group, were designed and synthesized as discussed by the authors.

TL;DR: In this paper, a novel copper selective sensor based on hydrazide and salicylaldehyde has been designed and prepared, which behaves a single selectivity and sensitivity in the recognition for Cu2+ over other metal ions such as Fe3+, Hg2+, Ag+, Ca2+, Zn2+, Pb2+, Cd2+, Ni2+, Co2+, Cr3+ and Mg2+ in DMSO.

TL;DR: In this paper, a new sensor 2,2′-((1E, 1′E)-((3,3′-dimethyl]-1,1′-biphenyl]-4,4′-diyl)bis(azanylylidene))bis(methanyly lidene)diphenol (YT) based on the combination of phenolic hydroxy and imine groups was used as an efficient colorimetric and "turn on" fluorescent sensor for fluoride anions.

TL;DR: In this article, a carboxylic acid-functionalized benzimidazole was synthesized, which could form an organogel (C11-OG) and generate a metallogel with Pb2+.

TL;DR: A novel approach to design ultrasensitive responsive materials by rationally introducing the aggregation-induced emission (AIE) effect into supramolecular polymer gels is reported, which can act as an AIEgen and could ultrasensitively detect heavy metal ions.
