八烷氧基2,3-萘酞菁锌(Ⅱ)的合成及荧光光谱研究

STUDIES ON SYNTHESIS AND FLUORESCENCE SPECTRA OF THE OCTAALKOXY 2,3 NAPHTHALOCYANINES ZINC(Ⅱ)

采用在强有机碱１，８－二氮杂双环［５，４，０］＋－－７烯（简称ＤＢＵ）存在下的醇溶剂中，由“分子碎片”与锌盐通过模板反应的新方法合成了一组八烷氧基２，３－萘酞菁锌配合物（Ｚｎ（ＲＯ）８ＮＰｃ，其中Ｒ＝Ｃ４Ｈ９、Ｃ８Ｈ１７、Ｃ１２Ｈ２５，ＮＰｃ＝Ｃ４８Ｈ１６Ｎ８）。产物进行了元素分析和红外光谱分析，并研究了它们在不同溶剂中的荧光光谱。

5, 9, 14, 18, 23, 27, 32, 36 octaalkoxy 2,3 naphthalocyanines(Zn(RO) 8NPc, R=C 4H 9、 C 8H 17 、 C 12 H 25 , NPc=C 48 H 16 N 8) and ZnNPc have been synthesized by a new method—the template reaction of “molecular fragments”—1,4 dialkoxy 2,3 dicyanonaphthalene or 2,3 dicyanonaphthalene with anhydrous zinc chloride in n amyl alcohol in the presence of 1,8 diazabicyclo undec 7 ene(DBU). These coordination compounds have been characterized by elemental analysis and IR. The fluorescence properties of the coordination compounds at 12℃ (excited at 700 nm, 5.0×10 -5 mol·dm -3 ) have been studied in different organic solvent.
