概要

• 論文の詳細を見る

• The absorption and fluorescence spectra in different solvents and at various pH have indicated that monocation and dication of 2-(<I>p</I>-aminophenyl)benzimidazole (PBNH<SUB>2</SUB>) are formed by protonating first the tertiary amine nitrogen atom and then the amino group, both in S<SUB>0</SUB> and S<SUB>1</SUB> whereas the monoanion in S<SUB>0</SUB> is obtained by deprotonating the imino group but in S<SUB>1</SUB> it is formed by deprotonating the amino group. Dianion at H<SUB>–</SUB>15 in S<SUB>1</SUB> is obtained by deprotonating the amino and then imino group.
