Abstract: In this paper, copper (Ⅱ)-tetra-4-(8-quinoloxy) phthalocyanine (A), 4-(8-quinolyoxy)tris-4-(2,4-di-t-pentyl phenoxy)phthalocyanine(B), tetra-4-(β-naphthoxy)phthalo-cyanine(C); 4-(β-naphthoxy)tris-4-(2, 4-di-t-pentyl phenoxy)phthalocyanine(D), tetrakis-4-[4'-4''-benzyloxy phenyl sulfonyl) phenoxy]phthalocyanine(E) and 4-[4'-4''-benzyloxy phenyl sulfonyl) phenoxy]-tris-4-(2, 4-di-t-penoxy)phthalocyanine(F), were synthesized and characterized by elemental analysis, IR, ESR, MSand ¹H NMR.UV-Vis spectra indicate that most of them are monomeric molecules in CHCl₃ solution.Surface pressure(π-area (A) isotherms for the six kinds of compounds in CHCl₃ solution in subphase (water) at 25℃ showed the existence of the obvious changes in the states of “gas", “liquid" and “solid" phases and six kinds of compounds could form monomolecular layer film.

Key words: Phthalocyanine copper(Ⅱ) derivative, Synthesis, LB film, π-A curve
