Abstract

with limit of detection (LOD) of 0.060, 0.034 and 0.124 ppm in THF, ACN, and DMSO, respectively. Furthermore, Im-2TH and Di-OMeIm-2TH were employed for trace water detection in real samples such as cement, sand, sugar, salt and detergent powder. A smart phone-based fluorometric assay is developed for the recognition of colour variation and RGB array profiles to facilitate the detection of water content in organic solvents for real-time monitoring.
