In contrast, at room temperature, the CP 34 exhibited two emission peaks between 350-490 nm and 490-700 nm respectively, corresponding to the monomer and excimer coming from the anthracene unit of the coordinated ligand L25 . With lowering the temperature, both the peak intensities enhanced, while further cool down around SCO region of 230 K, the monomer signal intensity increased highly with concomitant quenching of the signal of the excimer. The thermal SCO was established, depending upon the luminescence properties of 34 which is matching well with the SCO characteristics obtained from magnetic measurements, suggesting the synergic relationship among luminescence and properties in 34.
