The novel bis(monoaza-crown ether) diarylethenes 1 and 2 have been synthesized and their photochromism and the ion-complexation properties of both photoisomers have been investigated.

N-Oligoethylene glycol monoaza crown ethers were prepared, and the notable effect of oxyethylene oxygen atoms of the side chain on complexing ability with sodium and potassium cations was confirmed.
## Abstract Five new protonโionizable macrocyclic ligands containing a pyrimidoneโsubcyclic unit, 6โ10, were prepared from the previously prepared pyrimidinocrown ethers 1โ5 (see Figure 1 and Scheme 1). One of the new protonโionizable crown ethers is chiral. The protonโionizable pyrimidonocrown eth
