Sensing mechanism based on binding 0.5-ppm solution of Bi(III) ion with organic chromospheres (DZ) in solution-phase. The binding led to color change which corresponds to the formation of complex between the Bi(III) ion and DZ, and the final interaction of the formed complex with the mesoporous TiO2 led to the formation of highly stable TiO2-[(DZ)3-Bi] complex.
