  Efficient Routes for the Synthesis of Dinaphthosulfide (BINOL Derivatives) and Dibenzosulfide Aza Podands Containing Ethanolamine

  摘要：

  Four new dinaphthosulfide and dibenzosulfide aza podands were synthesized. The synthesis of these podands was performed under three different reaction conditions: 1) diester, K(2)CO(3), methanol, and RT; 2) diester, ethanolamine, and microwave (MW); and 3) diacid dichloride, ethanolamine, Et(3)N, CH(2)Cl(2), RT. Two kinds of diester (dinaphthosulfide and dibenzosulfide) were used for the preparation of dihydroxy podands. These dihydroxy podands were reacted with thionyl chloride to afford dichloro podands. The second route gave excellent yields of dihydroxy podands. Dichloro podands are more soluble than dihydroxy podands in conventional solvents such as methanol, chloroform, and acetonitrile.

  Benzimidazole Conjugate of 1,1′-Thiobis(2-naphthol) as Switch-On Fluorescence Receptor for Ag⁺ and the Complex as Secondary Recognition Ensemble toward Cys, Asp, and Glu in Aqueous Methanolic Solution: Synthesis, Characterization, Ion and Amino Acid Recognition, Computational Studies, and Microscopy Features

  摘要：

  A new 1,1'-thiobis(2-naphthoxy)-based receptor molecule (L) containing a benzimidazole moiety has been synthesized and characterized by H-1 NMR, ESI-MS, and elemental analysis. The selectivity of L has been explored in aqueous methanol, resulting in selective (7.5 +/- 0.5)-fold switch-on fluorescence response toward Ag+ among 14 different transition, alkali, and alkaline earth metal ions studied. The complexation of Ag+ by L has been addressed by ESI-MS, H-1 NMR, and UV-vis spectra. Microstructural features of L and its Ag+ complex have been measured by AFM and TEM. The morphological features of L alone and L in the presence of Ag+ differ dramatically both in shape and size, and the ion induces the formation of chains owing to its coordinating ability toward benzimidazole. Further, the in situ [Ag+-L] complex was titrated against 20 naturally occurring amino acids and found that this complex acts as a secondary recognition ensemble toward Cys, Asp, and Glu by switch-off fluorescence.
