Abstract：In 0.01 mol·L-1 HCl medium, red color [PtI6]2- and quinine combine to form association molecule. The molecules aggregate automatically owing to strong hydrophobic and molecular forces. And PtI6-quinine association particles with violet-red color formed. It exhibits three resonance scattering peaks at 310 nm, 400 nm and 610 nm, and a Rayleigh scattering peak at 470 nm. The absorption values all increase in the wavelength range of 350-740 nm, and the fluorescence peak at 450 nm was quenched. Under the conditions chosen, the quinine concentration in the range of 0-40×10-6 mol·L-1 is linear to the A620 nm value. The mole absorption coefficient ε620 nm is 1.31×104 L·mol-1·cm-1. The results show that the association particles produce the resonance scattering effect, fluorescence quenching and the violet-red color.
