Mono- and bispyridinium salts are shown to bind strongly with carboxylates in polar media through multiple hydrogen bonds and additional electrostatic interactions. The association constants of monopyridinium salt with various benzoates are in the range of 110-430 M-1 in DMSO-d(6), depending on substituents, while those between bispyridinium salts and adipate are >10(3) M-1 in 10% D2O/DMSO-d(6).

Design and synthesis of anthracene-based bispyridinium amides: anion binding, cell staining and DNA interaction studies
The design and synthesis of anthracene labeled bispyridinium amides 1–4 along with their anion binding, cell staining and DNA interaction studies are reported. All the chemosensors exhibit significant response towards H2PO4− in CH3CN. Furthermore, sensors 2 and 3 are quite interesting for the selective sensing of aliphatic dicarboxylates. Among these compounds, 1 is found to be useful in cell staining
报道了蒽标记的双吡啶吡啶鎓1-4的设计和合成,以及它们的阴离子结合,细胞染色和DNA相互作用研究。所有的化学传感器表现出对ħ显著响应2 PO 4 -中CH 3 CN。此外,传感器2和3对于选择性感测脂肪族二羧酸盐非常有趣。在这些化合物中,发现1可用于细胞染色。而且它们全部都表现出与DNA的显着相互作用。发现所有这些性质取决于保持吡啶鎓结合位点的间隔基的性质。
