Syntheses and Absorption Spectra of Polymethine Cyanine Dyes Such as Squarylium and Croconium Dyes
Squarylium, Croconium계 기능성 색소의 합성과 흡수 스펙트라
Abstract
The synthesis and absorption spectra of squarvlium(SQ) dyes and croconium(CR) dyes were .studied. Absorption spectra of SQ dye in various solvents exhibited a negative solvatochrornism. Thus, it was suggested that the structure of SQ dye may be a highly polar structure. The λ
