Metal-free phthalocyanine derivatives 2 and 14 bearing
eight and four
peripheral tetrathiafulvalene (TTF) units, respectively, have
been synthesised, and their solution electrochemistry and optical
spectroscopy have been studied. The compounds display redox properties
arising from the TTF and from the phthalocyanine groups. 1H
NMR and UV–VIS spectroscopic studies in solution show that
aggregation is strongly solvent dependent. Quenching of the fluorescence
of the phthalocyanine core by the TTF units was observed. The X-ray
crystal structure of
4,5-bis(hexylthio)-4′,5′-bis(hydroxymethyl)-TTF 11, which
was synthesised during the course of this work, has been determined. The
hydroxy groups of 11 engage in intermolecular (and interstack) hydrogen
bonds. Computer modelling studies on phthalocyanine derivatives 2 and 14
are reported.
无金属酞菁衍生物2和14分别带有八个和四个外围的四硫富瓦烯(TTF)单元,已被合成,并研究了它们的溶液电化学和光学光谱。这些化合物表现出源自TTF和酞菁基团的氧化还原特性。溶液中的1H核磁共振和紫外-可见光谱研究显示,聚集强烈依赖于溶剂。观察到TTF单元对酞菁核心的荧光淬灭效应。在此工作中合成的4,5-双(己硫基)-4',5'-双(羟甲基)-TTF 11的X射线晶体结构已被测定。11的羟基参与了分子间(及堆叠间)的氢键。报告了关于酞菁衍生物2和14的计算机模拟研究。
