New 2,9,16,23-tetra[o-(hydroxymethyl)benzyloxy]-substituted phthalocyanines were synthesized. Their reaction with 4-bromopyridine afforded 2,9,16,23-tetra[o-(4-pyridyloxymethyl)benzyloxy]-substituted analogs, treatment of which with HCl led to water-soluble pyridinium salts. Spectroscopic properties of the phthalocyanines obtained were studied and a hypsochromic shift of the Q-band of the hydrochloride
合成了新的 2,9,16,23-四[o-(羟甲基) 苄氧基]-取代的酞菁。它们与 4-溴吡啶反应得到 2,9,16,23-四[o-(4-吡啶氧基甲基)苄氧基]-取代的类似物,用 HCl 处理得到水溶性吡啶盐。研究了所获得的酞菁的光谱性质,并观察到与相应的吡啶鎓类似物相比,盐酸盐的 Q 带的低色位移。
