Synthesis of Novel Oxazolidines and Study of Its Naked Eye CO2 Detecting Properties
Herewith, we synthesized the new oxazolidines (SP-1, SP-2 and SP-3) by without using any withdrawing or donating substitution, and for these molecules we demonstrated CO2 sensing properties in naked eye condition with different colors (yellow and magenta). All the dyes showed
different colors in the presence and absence of CO2 in ethanol solution with the concept of ring closing and opening. In UV-visible absorption spectrum all the compounds showed visible light absorptions after purging of CO2. To confirm this mechanism for SP-1 molecule
case, we approached the 1H-NMR and 13C-NMR techniques deuterated methanol as a solvent and we clearly identified. The stability of the SP-1 molecule in ethanol for CO2 purging case, we studied repeatability test up to ten cycles and we confirmed that there
is no any decrease in sensing ability.
