R 7 is

with an anion A − ;
k is 1;
A − is Cl − , Br − , ClO 4 − , NO 3 − , HSO 4 − , BF 4 − or PF 6 − ; and
R 10 is methyl.

2. The compound of formula (1) according to claim 1 wherein
R 1 , R 2 , R 3 , R 4 are hydrogen;
R 5 is hydrogen;
R 6 is hydrogen;
R 7 is

with an anion A − ;
k is 1;
A − is Cl − or Br − ; and
R 10 is methyl.
