Abstract

Background: Multifunctional fluorescent probes have attracted much attention due to their wide range of applications and high utilization. In this study, a multifunctional fluorescent probe (E)-3-(4-(7-(4-(diphenylamino)phenyl)benzo[c] [1,2,5]thiadiazol-4-yl)phenyl)acrylic acid (TBAC) based on triphenylamine was designed and synthesized.

Results: The TBAC probe provided excellent aggregation-induced emission (AIE) performance and could be used as a fluorescent ink for printing. It was also prepared successfully for application as a fingerprint powder, facilitating the visual detection of invisible fingerprints on surfaces such as glass, plastic, tinfoil, metal, aluminum, and resin. The probe exhibited a clear fluorescence response to 12 volatile amines via an AIE-based 'on-off' mechanism in an EtOH/H₂O (4/6, v/v) solution. The TBAC/bromocresol green (BCG) indicator label also enabled non-destructive and rapid assessment of salmon freshness through dual-channel colorimetric and fluorescence responses.

Conclusion: The versatility of TBAC makes it a promising material for various applications, including fluorescent materials, criminal detection, and food safety. This study provides a new basis for the multifunctional application of fluorescent probes. © 2025 Society of Chemical Industry.

期刊介绍： The Journal of the Science of Food and Agriculture publishes peer-reviewed original research, reviews, mini-reviews, perspectives and spotlights in these areas, with particular emphasis on interdisciplinary studies at the agriculture/ food interface. Published for SCI by John Wiley & Sons Ltd. SCI (Society of Chemical Industry) is a unique international forum where science meets business on independent, impartial ground. Anyone can join and current Members include consumers, business people, environmentalists, industrialists, farmers, and researchers. The Society offers a chance to share information between sectors as diverse as food and agriculture, pharmaceuticals, biotechnology, materials, chemicals, environmental science and safety. As well as organising educational events, SCI awards a number of prestigious honours and scholarships each year, publishes peer-reviewed journals, and provides Members with news from their sectors in the respected magazine, Chemistry & Industry . Originally established in London in 1881 and in New York in 1894, SCI is a registered charity with Members in over 70 countries.
