Insights into tautomerism and pH effects on the photoluminescence of citric acid-derived molecular fluorophores

LELaura EstévezNONicolás Otero

Key Points

  • The research aims to explore how tautomerism and pH levels affect the photoluminescence properties of molecular fluorophores derived from citric acid.
  • Analysis of tautomerism and its impact on photoluminescence
  • Evaluation of pH effects on molecular fluorophores
  • Examination of optical properties of citric acid-derived carbon dots.
  • Identified key factors of tautomerism influencing photoluminescence intensity.
  • Demonstrated pH-dependent behavior affecting the spectral properties of fluorophores.
  • Showed significant contributions of citric acid-derived compounds to photoluminescent properties.

Abstract

Photoluminescence mechanism of two representative molecular fluorophores known to significantly contribute to PL properties of citric acid-derived CDs.
