On the nature of the lowest electron transitions in the borine dye derivatives benz[cd]indole

[Display omitted] •The new series of cationic cyanine dyes were synthesized.•Cyclization of the both terminal groups by BF2 bridge changes the total charge in the symmetrical dyes.•Cyclization of the both terminal groups by BF2 bridge practically does not change the optical properties of dyes.•High...
