of recent advances and improvements on this class of compounds are reported in the art. This paper presents our latest work on the improved synthetic approach, study on photophysical properties, and biosensing applicability of monomethine cyanine dyes. The series of mono-, di- and tricationic dyes showed up to 5-fold enhanced resistance against photobleaching compared to the commercially available Thiazole

The scope of intramolecular radical-induced substitution of pyridinium salts has been investigated, and it has been shown that [5,6] and [6,7]-membered fused ring systems form with surprising efficiency.

Several two- and three-cationic monomethine cyanine dyes, possessing a benzothiazolium moiety were synthesized and evaluated as initiators of the free radical polymerization of 2-ethyl-2-(hydroxymethyl)-1,3-propanediol triacrylate under visible light. Dyes bearing 1-methylpyrrolidinium, 4-methylmorpholinium, pyridinium and 3-(N,N-dimethylamino)propan-1-ol substituents were useful initiators. All derivatives absorbed in the region 510-570 nm and displayed molar absorption coefficients of 40 000-60 000 dm(3) mol(-1) cm(-1). A kinetic study of photoinitiated polymerization performed with the use of the electron donor n-butyltriphenylborate salt showed that the dyes were efficient two-component photoinitiators.
