The invention relates to a triaza-cryptand of the general Formula I
wherein
a is selected from the group consisting of 0 and 1,
b and c independently are selected from the group consisting of 0 and 1, with the proviso that not both of b and c are 0,
d is selected from the group consisting of 1, 2 and 3,
e and f independently are selected from the group consisting of 0 and 1, with the proviso that not both of e and f are 0,
R1 and R2 are either hydrogen or form an alkyl(C1-C4) benzene ring or an alkoxy(C1C4) benzene ring together with C1 and C2, wherein C2 is the para position,
R3 and R2 are either hydrogen or form an alkyl(C1-C4) benzene ring or an alkoxy(C1-C4) benzene ring together with C3 and C4, wherein C3 is the para position,
R5 and R6 are either hydrogen or form a benzene ring or a naphtalene ring together with C5 and C6,
R7 and R8 are either hydrogen or form an alkyl(C1-C4) benzene ring or an alkoxy(C1-C4) benzene ring together with C7 and C8, wherein C8 is the para position,
R9 and R10 are either hydrogen or form an alkyl(C1-C4) benzene ring or an alkoxy(C1-C4) benzene ring together with C9 and C10, wherein C9 is the para position,
X is a luminophoric moiety in ortho, para or meta position with respect to the nitrogen and m is selected from the group consisting of 0, 1 and 2.
The triaza-cryptand of the invention is useful as a luminescence indicator for alkali ions.
