• visible region, PPIX shows a very low efficiency probably because of the inadequate absorbance in the NIR region. Squarines are widely known red/NIR-absorbing organic dyes that can be used as a co-sensitizer with a visible absorbing dye to get a wide panchromatic absorption. From the structure of SQ2
