Ohira, Kazuki;Imato, Keiichi;Ooyama, Yousuke research published 《 Development of phenazine-2,3-diol-based photosensitizers: effect of formyl groups on singlet oxygen generation》, the research content is summarized as follows. Phenazine-2,3-diol derivatives KO-0-3, which have zero to three formyl groups, resp., have been developed as photosensitizers (PSs) possessing the ability to generate singlet oxygen (1O2). The photoabsorption bands of KO-0-3 are significantly red-shifted compared to those of phenazine-2,3-MOM (methoxymethyl) derivatives 5-8, whose hydroxy and formyl groups are protected, and have onsets at around 600-650 nm. Furthermore, the fluorescence quantum yields (Φfl) of KO-0-3 (Φfl = 0.024-0.097) are lower than those of 5-8 (Φfl = 0.34-0.46) in solution To gain insight into the 1O2 generation properties of KO-0-3, we evaluated the 1O2 quantum yields (ΦΔ) and rate constants (kobs), and demonstrated that KO-1-3 possess a higher ability to generate 1O2 under visible light irradiation than those of 5-8. Moreover, it was found that the ΦΔ values of KO-0-3 increase in the order of KO-0 (0.036) < KO-1 (0.22) < KO-2 (0.33) < KO-3 (0.41) with increasing number of formyl groups. This result indicates that formyl groups facilitate the intersystem crossing (ISC) from the lowest singlet excited states of the PSs (S1) to the triplet excited states (Tn) according to El-Sayed′s rule. Consequently, this work provides useful knowledge in mol. design of efficient phenazine-2,3-diol-based PSs for photodynamic therapy (PDT).

4-Bromobenzene-1,2-diamine, also known as 4-Bromobenzene-1,2-diamine, is a useful research compound. Its molecular formula is C6H7BrN2 and its molecular weight is 187.04 g/mol. The purity is usually 95%.
4-Bromo-1,2-diaminobenzene is a dye that is used in diagnostic
procedures to detect the presence of amide groups. 4-Bromo-1,2-diaminobenzene can be used as an inhibitor for cationic polymerization reactions. It also has tuberculostatic activity and inhibits the growth of Mycobacterium tuberculosis. This compound reacts with aniline to form a benzimidazole derivative that contains a reactive amine group. The reaction between this amine group and different electrophiles generates benzimidazole compounds with different properties that are useful in nucleophilic attack reactions. The reaction between 4-bromo-1,2-diaminobenzene and methyl ethyl sulfide produces a luminescent probe that can be used to detect hydrogen bonds., HPLC of Formula: 1575-37-7
