β¦ Synopsis
We describe the synthesis of bis(3-{4-[2%-(4-methoxyphenyl)-3H,3%H-[5,5%]bibenzimidazolyl-2-yl]phenoxy}propyl)methylamine 8, which has high affinity for the oligonucleotide sequence [A.T] 4 -[G.C]-[A.T] 4 .

Two new neutral receptors (1 and 2) containing (thio)urea and amide groups were synthesized by simple steps in g o d yields. The binding properties for anions of 1 and 2 were characterized by W-vis and fluorescence spectra. Receptor 1 had 811 excellent selectivity for A&-in comparison with other ani
## Abstract Bisβ9βacridinyl derivatives 1β3 containing monoβ, diβand tetraβviologen units as a rigid connector were synthesized. The binding studies of these intercalators for natural and synthetic DNAs showed that these compounds act as bisβintercalators where viologen moieties lie in the minor gr
