八丁氧基-2,3-萘酞菁铜(Ⅱ)的合成与UV光谱研究
Studies on Synthesis and UV Spectrum of Octabutoxy-2,3-naphthalocyanine Copper
摘要
采用分子碎片法合成了5,9,14,18,23,27,32,36-八丁氧基-2,3-萘酞菁铜,利用元素分析、红外及紫外可见光谱进行了表征.配合物的电子吸收光谱表明:新配制的氯仿溶液中萘酞菁铜的Q带H聚集体和单体的吸收峰在758、854nm处,5h后单体和H聚集体的吸收峰基本消失,出现了798和909nm的错位H/J聚集体以及960nm的J聚集体吸收,12h后主要以795nm的H聚集体形式存在.
Abstract
5,9,14,18,23,27,32,36-Octabutoxy-2,3-naphthalocyanine copper(II) was synthesized by using molecular fragments method. It was characterized by elemental analysis and IR spectra as well as UV absorption in CHCl3. The results show that the absorptions at 758 and 854nm were assigned to Q-bands of H-aggregate and monomer in fresh solution. After 5 hours, the monomeric and H- aggregate absorptions disappeared and new absorption bands were observed corresponding to the absorption of vicarious H (798nm)/ J (909nm) aggregate and J (960nm) aggregate. 12 hours later, there was a broad absorption band at 795nm (H-aggregate) observed in chloroform solution.
