7. Deprotonation of the hydroxy group of fluorescein causes a red shift in fluorescence spectra. Coordination of the hydroxy group to the titanium atom presumably induces a similar red shift.
8. Acidic octyltrichlorosilane and tert-butylphosphonic acid yield deep yellow and orange-colored solutions, respectively, due to neutralization of the hydroxy group of fluorescein.
