Aggregation of unsymmetrical anionic carbocyanine. I. Preparation and aggregation of sodium salt of 1′-ethyl-3,3′-bis-(3-sulfopropyl)-5-methoxy-5′,6′-dichlorobenzimidazolooxacarbocyanine was written by Huang, Guangtuan;Lu, Minghu;Huang, Deyin. And the article was included in Huadong Ligong Daxue Xuebao in 1998.Name: 2,5-Dimethylbenzoxazole This article mentions the following:
The anionic carbocyanine dye, sodium salt of 1′-ethyl-3, 3′-bis-(3-sulfopropyl)-5-methoxy-5′,6′-dichloro-benzimidazolo-oxa-carbocyanine and its intermediates were synthesized. Its structure has been characterized by IR, 1H-NMR and MS. UV-Vis spectra of this dye in Me alc., water, 1,2-dichloroethane, chlorobenzene and bromobenzene have been determined This dye could not form J-aggregate when its concentration was 1 x 10-5 mol/L in Me alc. and water. When it was dissolved in 1,2-dichloroethane, chlorobenzene and bromobenzene, it tended to form J-aggregate. The process of aggregation has also been studied for the solution of this dye dissolved in chloroform. In the experiment, the researchers used many compounds, for example, 2,5-Dimethylbenzoxazole (cas: 5676-58-4Name: 2,5-Dimethylbenzoxazole).
2,5-Dimethylbenzoxazole (cas: 5676-58-4) belongs to benzoxazole derivatives. Benzoxazole derivatives have different biological activities. A number of marketed drugs are available having benzoxazole as core active moiety like, nonsteroidal anti-inflammatory drug (NSAID)—flunoxaprofen, benoxaprofen, antibiotic—calcimycin.Name: 2,5-Dimethylbenzoxazole
