암모니움 이온을 가진 카드뮴 호스트 착물의 방향족 게스트 분자에 대한 포접선택성 변화

Abstract

Inclusion selectivities of the cyanocadmate host complexes with ammonium oniums, [Cdx(CN)2x][onium·zG] (onium = NMe3Et+, NMeEt3+ and NEt4+, G = guest), have been investigated for C6H6 (B), PhMe (T), PhEt (E), ortho (O), meta (M), and para (P) isomers of C6H4Me2 as the aromatic guest molecules. From the binary, ternary, quaternary and quinary mixed guests of B, T, E, O, M and P, the order of preference in the NMe3Et+-host is B T＞P O M and E＞O P M; in the NMeEt3+-host is T＞B＞P O M and E＞P M＞O; in the NEt4+-host is B T O M P. However, the NEt4+-host complexes of E, O, M and P mixed-guests were not obtained. These inclusion selectivities were compared to our previous results of the NMe4+-host; T＞B＞P M＞O and E＞P M＞O.
