A design concept of long-wavelength fluorescent analogs of rhodamine dyes: replacement of oxygen with silicon atom.
Replacement of the oxygen with a silicon atom on the rhodamine framework produces a strong red-emission fluorophore which has a high molar extinction coefficient and 90 nm red shift relative to rhodamine dye PY.
