Significance
Long-wavelength fluorescent dyes are relevant in biology because they can avoid the interference of inherent biological fluorescence. The substitution of oxygen atom by silicon in a rhodamine scaffold results in a bathochromic shift of absorption and emission. Despite the low quantum yields reported, this is an innovative strategy to tune the optical properties of dyes.
