platinum-acetylide copolymers with thiophene, selenophene, and tellurophene have been synthesized and studied. Photoluminescence experiments show that polymers undergo intersystem crossing to triplet states, leading to phosphorescence. The observed phosphorescence decreases in intensity moving down the group. DFT calculations are used to further understand the optical properties.
合成并研究了一系列与噻吩,硒基硒和碲二酚的铂-乙炔共聚物。光致发光实验表明,聚合物经历系统间交叉而变成三重态,从而导致磷光。观察到的磷光强度沿组向下移动而降低。DFT计算用于进一步了解光学特性。
