Aggregation and photofading behaviour of unsymmetrical squarylium dyes containing a quinolylidene moiety
View through CrossRef
Representatives of a new class of unsymmetrical squarylium dyes containing a quinolylidene moiety have been synthesised and characterised. These dyes absorbed at a longer wavelength (11–50 nm) than the corresponding symmetrical squarylium dyes. The influence of the quinolylidene moiety on the absorption of these dyes was studied and compared with that calculated by the PPP‐MO method. The photostability properties of the dyes were investigated in chloroform with a high‐pressure mercury lamp. The aggregation of the unsymmetrical squarylium dyes were also studied in different DMSO/water solutions, including solutions with γ‐cyclodextrin.
