| Abstract: | A novel chiral conjugated polymer with chiral 1,1-binaphthyl and 2,2-bipyridyl units was prepared. The ion responsive properties of the polymer were measured in tetrahydrogenfuran by using absorption, emission spectra and optical rotation. The results show that absorption, emission spectra and optical rotation of the polymer solutions have different responses with interactions of different transition metal ions. The mechanism is that different changes of electrical and steric effects of the polymer can cause different changes of the properties of the polymer when interacting with different transition metal ions. The novel chiral polymer could be used for metal ion sensing. |
