Multiple switchable circularly polarized luminescence from nucleotide/terbium(iii) complexes

We found that the complexes of nucleotides and terbium(iii) exhibit circularly polarized luminescence (CPL). The CPL of GMP/Tb/Ag coordination polymer nanoparticles (CPNs) was converted by a magnetic field and pH. The CPL of the purine nucleobase of nucleotides was opposite to that of the pyrimidine nucleobase. GMP/Tb/Ag CPNs could be used as advanced safety coatings and acid-base switches, and Tb/Ag could be used as CPL probes for rapid differentiation of nucleotides, which provided ideas for multiple transformations and applications of CPL.

Automated summary

We discovered that the complexes formed by nucleotides and terbium(iii) exhibit circularly polarized luminescence (CPL). The CPL of GMP/Tb/Ag coordination polymer nanoparticles (CPNs) can be manipulated by a magnetic field and pH. The CPL of purine nucleobases is opposite to that of pyrimidine nucleobases. GMP/Tb/Ag CPNs can be used as advanced safety coatings and acid-base switches, while Tb/Ag can serve as CPL probes for rapid differentiation of nucleotides, providing insights into the multiple transformations and applications of CPL.
