Polynucleating open-chain systems with imidazole and proton-ionizable 1,2,4-triazole structural motifs.
A multistep route for obtaining the polynucleating open-chain systems 3-5 is reported. These advanced intermediates required elaborate processes that proceeded for the pentanuclear protophanes 3 in seven steps, whereas the trinuclear compounds 4 and 5 were obtained in six steps
