“…Previous works reveal that its abnormality is correlated with various diseases, such as Parkinson, Huntington, aprosexia and schizophrenia. , In addition, DA analogues, including levodopa (DOPA), levodopa lethyl ester hydrochloride (DOPAM), and norepinephrine (LNAA), usually show different biological functions even containing a DA unit. To facilitate the understanding of its biological function and diagnosis of related diseases, a variety of DA detection methods with high sensitivity have been explored. − For example, the reaction-based DA sensing probes attract growing attention due to the favorable selectivity over other catechols. − However, few DA analogues still exhibit visible interference due to their similar molecular structure and chemical reactivity. Moreover, some analogues can be transformed into others by enzymatic catalysis.…”

The selective recognition of dopamine (DA) over other neurotransmitter analogues is difficult due to the similar molecular structure and chemical reactivity. In this study, substitution-regulated chemical reactivity of the sensing substrate is utilized to explore a novel DA detection probe with satisfying selectivity. As a case study, 3,5-dihydroxybenzoic acid (DHBA, carboxy-substituted resorcinol)-based probes have been explored for selective and ratiometric DA sensing. The carboxy substitution benefits the stabilization of the carbanion intermediate and the azamonardine product, which enhances the reaction kinetics and thermodynamics and subsequently facilitates selective DA recognition over other analogues and interferents. By exploring DHBA emission as the internal reference, ratiometric fluorescence variation is realized, which contributes to sensitive DA analysis. With the combination of logic gate and fluorometric analysis, DA detection in both low and high concentrations can be readily achieved. In addition, the DA analysis in biological samples and the enzymatic transformation of DA analogues in cerebrospinal fluid samples are achieved by the proposed DHBA probe.
