The design and synthesis of molecular probes competent for pH signaling within or beyond a certain range is a complicated matter. Herein a new mechanism for ''OFF-ON-OFF'' absorbance and fluorescence intensities vs. pH behaviour is described. The probe design is

In this study, we synthesized a simple but efficient quencher-free molecular beacon tethering 7-hydroxycoumarin on D-threoninol based on its pK(a) change. The pK(a) of 7-hydroxycoumarin in a single strand was determined as 8.8, whereas that intercalated in the duplex was

Ortho-hydroxylation of cinnamates is a key step in coumarin biosynthesis in plants. Ortho-hydroxylated cinnamates undergo trans/cis isomerization of the side-chain and then lactonization to form coumarins. Sweet potato [Ipomoea batatas (L.) Lam.] accumulates umbelliferone and scopoletin after biotic and abiotic
