Water-soluble phthalocyaninato zirconium(IV) and hafnium(IV) complexes have been synthesized for the first time. An increased solubility in comparison to PcZrCl 2 and PcHfCl 2 was caused by the introduction of gallic, 1,8-dihydroxynaphthalene-3,6-disulfonic (chromotropic), and 5-sulfosalicylic acids in the axial position. The new compounds were characterized by 1 H NMR, IR, UV-vis and elemental analysis.

有机配体轴向取代锆(IV)和铪(IV)酞菁的合成及性能

首次合成了水溶性酞菁锆(IV)和铪(IV)配合物。与 PcZrCl 相比，溶解度增加2和 PcHfCl2是由在轴向位置引入没食子酸、1,8-二羟基萘-3,6-二磺酸（变色）和5-磺基水杨酸引起的。新化合物的特点是1H NMR、IR、UV-vis 和元素分析。
