The synthesis of a benzenethiol-derivatized porphyrin for flat-lying self-assembly on gold substrates is described. Acetyl protected thiol is not stable enough in Pd-catalyzed reactions. While acrylate derivatives protected thiol group shows good tolerance in Pd-catalyzed borylations and Suzuki-Miyaura coupling reactions and no catalyst poisoning was observed.

An efficient and practical method is described for the ring-opening reactions of N-tosylaziridines with various thiols in water under mild conditions. Various surfactants have been evaluated to optimize the reactions. Under optimal conditions, these reactions gave rise to the corresponding β-amino sulfides in good to excellent yields.

thiols play important roles in various physiological functions, and the discrimination of thiols is a significant but difficult issue. Herein, we presented a novel strategy for strengthening the discrimination of thiols by a facile colorimetric sensor array composed by a series of urease-metal ion pairs. Many metals ions, such as Ag, Hg, Cu, and Zn, can efficiently inhibit the activity of urease. Meanwhile, the sulfhydryl group of thiols has high affinity with these metal ions. On the basis of the interactions between thiols and metal ions and the effective activation of urease by thiols, four urease-metal ion pairs are taken to fabricate a colorimetric sensor array for discrimination of thiols. Different thiols exhibited different affinities toward the metal ions, producing differential retentions of urease activity and generating various colorimetric response patterns. These response patterns are characteristic for each thiol and can be quantitatively differentiated by linear discriminant analysis(LDA). Cysteine(Cys), glutathione(GSH), and four other kinds of thiols have been well distinguished on the basis of this sensor array at a low concentration(1.0 μM). Remarkably, the practicability of the proposed sensor array was further validated by high accuracy(96.67%) identification of 30 unknown thiol samples. In this strategy, urease and its metal ion inhibitors were adapted to fabricate the sensor array, offering a facile way to develop sensitive array sensing systems based on inexpensive and commercially available enzymes and their inhibitors.

A polarity-sensitive fluorescent probe MNP was rationally designed and synthesized with naphthalimide as the fluorophore and maleimide as the receptor for thiols. MNP is weakly fluorescent due to the photoinduced electron-transfer （PET） from the fluorophore to the receptor, and it displays evidently solvatochromic UV-vis and fluorescence spectra： the emission shifted from 495 nm in n-hexane to 545 nm in phosphate buffer solution. Michael addition reaction between thiols and the maleimide in MNP inhibited the PET process, which led to about eight-fold fluorescence enhancement. In addition, MNP showed highly sensitivity to rnercapto-containing proteins and it could detect as low as 20.4 μg/mL of BSA in PBS. MNP has potential in fluorescent imaging of thiols in living cells.
