and R
4
each independently represent a hydrogen atom or 1-3 identical or different substituents independently selected from the group consisting of a hydroxyl group, halogen atom, or an alkyl group, sulfo group, carboxyl group, ester group, amide group and azide group, each of which may be optionally substituted; R
5
, R
6
, R
7
and R
8
each independently represent a hydrogen atom or alkyl group, wherein, R
5
or R
6
, respectively together with R
3
, may form a ring structure including the nitrogen atoms bonded thereto, or R
7
or R
