Ici, des points carbonés fluorescents (N, SCD) co-dopés à l'azote et au soufre ont été synthétisés par pyrolyse simple et facile assistée par micro-ondes en utilisant du citrate d'ammonium et du chlorhydrate de cystéamine. Les N, SCD obtenus ont montré une photostabilité exceptionnelle, une indépendance de la longueur d'onde d'excitation, d'excellentes propriétés de fluorescence avec un rendement quantique de fluorescence (FLQY) allant jusqu'à 54,8%. De manière significative, la fluorescence de N, SCD a été efficacement inhibée par Cr (VI) sur la base de l'effet de filtre interne (IFE). Par la suite, la fluorescence du système N, SCD-Cr (VI) s'est rétablie avec l'addition d'acide ascorbique (AA) en raison de la réaction redox entre le Cr (VI) et l'AA. Par conséquent, N, SCD pourraient être utilisés comme sonde fluorescente "à blocage" efficace pour la détection hautement sensible du Cr (VI), avec une plage de détection de doublure de 0,35 à 126,0 molL (-1) et une limite de détection de 0,11 mololL ( -1). Pendant ce temps, le système N, SCD-Cr (VI) pourrait être utilisé comme capteur fluorescent "allumé" pour la détection des AA avec une limite de détection de 0,17 molL (-1) et une plage de détection de doublure de 0,57-264,0 mmolL ( -1). De manière intéressante, une porte à logique moléculaire a été construite sur la base de la récupération de fluorescence du système N, SCD-Cr (VI) en présence de AA. Plus important encore, cette sonde fluorescente a été appliquée pour la détermination du Cr (VI) et de l'AA dans des domaines environnementaux et biologiques avec des résultats satisfaisants.
