The 1,3-bis(4-aminoaryl)squaraines showed color change behavior, they were found to undergo
reduction with sodium borohydride in solution to give colorless leuco compounds, which oxidized readily in air
back to the colored squaraine dye. We have shown that initial observations indicated that the derivatives
synthesized gave new donor-acceptor chromophores. It is also interesting to note that the oxidation of the leuco
squaraines did initially produce a species absorbing about 630-680 wavelengths. The 1,3-squaraines have found
many uses as near-infrared absorbers, laser dyes and photoconductive materials. Furthermore their color-change
redox behavior has potential in the area of peroxidase-based bioassaysas oxidation sensitive indicator systems
were investigated. |
