Abstract

The 1,10-phenanthrocyanines of d-elements were investigated by ESR spectroscopy both in the solid (glassy) state and in solutions. These are coordination compounds of a new structural class of apocyanines: chromophore binuclear cation complexes [M²⁺L_n(µ-PC)]₂X_m (M²⁺ = Zn²⁺, Cd²⁺, Co²⁺, Pd²⁺and Pt²⁺; L = 1,10-phenanthroline, 2,9-Me₂-1,10-phenanthroline, pyridine; X = AcO⁻, Cl⁻) with electron-rich bridged 1,10-phenanthrocyanine ligands µ-PC. They are presented as soft colloidal glasses capable of acting as inhibitors of tumor cell proliferation, fungicides and DNA complexones. The study of them by ESR spectroscopy showed that one of the possible mechanisms for the formation of spin centers is thermally directed singlet–triplet S₀ → T_low.-transitions.

d元素生物活性富电子1,10-菲anthrocyanines的ESR光谱研究(软胶体玻璃)

用ESR光谱研究了d-元素中的1,10-邻菲蒽在固体(玻璃态)和溶液中的分布。这些是一种新的结构类罗布麻碱的配位化合物:发色团双核阳离子配合物[M2+Ln(µ-PC)]2Xm (M2+ = Zn2+， Cd2+， Co2+， Pd2+和Pt2+;L = 1,10-菲罗啉，2,9- me2 -1,10-菲罗啉，吡啶;X = AcO−，Cl−)与富电子桥接1,10-phenanthrocyanine配体µ-PC。它们呈现为软胶状玻璃，能够作为肿瘤细胞增殖抑制剂，杀菌剂和DNA络合物。ESR谱分析表明，自旋中心形成的可能机制之一是热定向单重态-三重态S0→flow跃迁。
