“…[9,[39][40][41][42][43][44][45]. Sensors for organic pollutants [46][47][48][49][50][51][52][53][54], especially anilines [51,52] and phenols [49,53,54], have been developed in both organic and aqueous solutions, as well as the mixtures. The fluorescent sensing mechanism is often based on analyte-binding-induced assembly-disassembly of PDIs, taking advantage of the sensitive dependence of fluorescence of PDIs on the π-π stacking interaction [5,6,10,[18][19][20][21]49,[52][53][54].…”

“…PDI-based optical sensors have proven efficient for detection of organic compounds of biology interest, e.g., ascorbic acid [46] and thyroid hormones [47], in aqueous media. With the similar sensing mechanism and molecular design strategy, PDI-based sensors have also been adapted into detection of toxic organic compounds, such as hydrazine, other amines and nitroaromatics [48][49][50][51][52][53][54].…”

Perylene tetracarboxylic diimide (PDI) and its derivatives exhibit excellent thermal, chemical and optical stability, strong electron affinity, strong visible-light absorption and unique fluorescence on/off features. The combination of these features makes PDIs ideal molecular frameworks for development in a broad range of sensors for detecting environmental pollutants such as heavy metal ions (e.g., Cu 2+ , Cd 2+ , Hg 2+ , Pd 2+ , etc.), inorganic anions (e.g., F − , ClO 4 − , PO 4 − , etc.), as well as poisonous organic compounds such as nitriles, amines, nitroaromatics, benzene homologues, etc. In this review, we provide a comprehensive overview of the recent advance in research and development of PDI-based fluorescent sensors, as well as related colorimetric and multi-mode sensor systems, for environmental detection in aqueous, organic or mixed solutions. The molecular design of PDIs and structural optimization of the sensor system (regarding both sensitivity and selectivity) in response to varying analytes are discussed in detail. At the end, a perspective summary is provided covering both the key challenges and potential solutions for the future development of PDI-based optical sensors.
