Abstract N,N ‐Di‐2‐picolylamine (DPA)‐derived diboronic acid receptors (NHBAs) with a flexible linker were designed and synthesized in this study, and two‐component sensing ensembles based on cationic NHBAs and an anionic fluorescent indicator 8‐hydroxypyrene‐1,3,6‐trisulfonic acid trisodium salt (HPTS) were successfully developed for both monosaccharides and disaccharides sensing. The dibranched ortho ‐substituted receptor NH o BA exhibited unexpected selectivity towards lactose among five disaccharides used. The discrimination of five disaccharides and six monosaccharides was finally achieved by the integrated sensor array through linear discriminant analysis (LDA).
