A : The by-products were obtained, when some phenols were used for the synthesis of the armed-macrocycles using the Mannich reaction. The reaction was carried out using 11 kinds of phenol, and the reaction mechanism was clarified from the results of pH measurements and static potential charging of p-carbon of the phenols. It is reveals that the reactivity for the Mannich reaction of the phenols would be estimated by pH measurement and the calculation of the static potential charge when 2,6-disubstituted phenols were used. B : The X-ray structural analysis for the RbSCN complexes of compounds 2 and 3 having i-Pr and x-Bu on phenol. As the results, 3-RbSCN having t-Bu groups in the side arm forms 1 : 1 complex, while 2-RbSCN having i-Pr groups forms the structure in which 1 : 1 complexes and polymeric (1 : 1)_n complex become alternate. When it was considered including 1-RbSCN complex with the Me groups being the polymeric (1 : 1)_n complex, it is revealed that the structures of the comp … More lexes systematically changed in these a series of the compounds by being dependent on the bulk of alkyl group introduced in to the side arm. C : In the RbSCN complex of the armed macrocycle which introduced F into both neighbors of hydroxyl group of the side arm, Rb^+ ion was coordinated by five hetero atoms on the crown ring and S atom of SCN salt, and 2 : 2 complex was formed. In addition, 8 coordinated structure was formed by the coordinating in F atom of the side arm of the other molecule. In this complex, the Rb+ ion was bounded by the F atom not the phenolic OH grotrp. D : It is revealed that 2 : 2 complexes are formed by the configuration to the potassium ion that the phenol of the side-chain was incorporated in other molecule, and the secondary inclusion field is formed in the KSCN complex of the armed-macrocycle in which MeO group was introduced in both neighbors of hydroxyl group of the side arm. The results suggested that functional groups which have stronger coordination ability toward metal ions may be introduced in the side arm in order to development of the host complexation by armed macrocycles.
