Article Synopsis
  • - The self-assembly of d transition metal complexes like Pt(ii) and Pd(ii) is crucial for creating advanced materials used in optoelectronics and sensing, but understanding their electronic behaviors when excited is still unclear.
  • - This study compares the excited-state behavior of self-assembled Pt(ii) and Pd(ii) complexes, revealing that while both have similar structures, their thermal responses differ significantly.
  • - The Pt(ii) complex displays a dramatic thermochromic luminescence shift when heated, while the Pd(ii) complex shows increased luminescence efficiency when cooled, highlighting their contrasting properties.

Copper-catalyzed azide-alkyne cycloaddition click (CuAAC) reaction is widely used to synthesize drug candidates and other biomolecule classes. Homogeneous catalysts, which consist of copper coordinated to a ligand framework, have been optimized for high yield and specificity of the CuAAC reaction, but CuAAC reaction with these catalysts requires the addition of a reducing agent and basic conditions, which can complicate some of the desired syntheses. Additionally, removing copper from the synthesized CuAAC-containing biomolecule is necessary for biological applications but inconvenient and requires additional purification steps.
