Abstract
A series of new heptamethine pyrylium dyes derived from enamine and enaminium salts has been prepared. Spectral absorptions of these dyes range from 850 nm to 1160 nm. Relation between the structure and chromophore has been discussed and kinetic study has been made on the configuration isomerization of the dyes. Photostability has been investigated in relation to the chemical structure.
