| 摘 要： | A series of 1,8,15,22-tetra(2,4-ditertbutylphen-oxy) phthalocyanines α-（oAr）4PcM,M1=(H)2,M2=Pd,M3=Cu,M4=Zn,M5=Pb] were synthesized in this study.Each compound was bromized in two kinds of solvent.One is the solvent mixture of 1,1,2-trichloroethane and water,the other is 1,1,2-trichloroethane alone.The effects of solvent,bromine excess added and reaction duration on the bromization reaction were studied.The shift of maximum absorbance wave-length both is solution and in solid thin film was investigated comparatively,discovering that both were bathochromism but the former was more.TG data showed that the temperature of thermal decomposition decreased continuously with the increase of numbers of bromine.Finally,the fragments produced during the bromization of (OAr)4PcPb in 1,1,2-trichloroethane were characterized by GC/MS.Based on the electronic structure,the possible mechanism of decomposition of these compounds was presented and discussed.

| Abstract: | A series of 1,8,15,22-tetra(2,4-ditertbutylphenoxy) phthalocyanines α-(oAr)4PcM, M1=(H)2, M2=Pd, M3= Cu, M4=Zn, M5=Pb] were synthesized in this study. Each compound was bromized in two kinds of solvent. One is the solvent mixture of 1,1,2-trichloroethane
and water, the other is 1,1,2-trichloroethane alone. The effects of solvent, bromine excess added and reaction duration on
the bromization reaction were studied. The shift of maximum absorbance wavelength both in solution and in solid thin film
was investigated comparatively, discovering that both were bathochromism but the former was more. TG data showed that the
temperature of thermal decomposition decreased continuously with the increase of numbers of bromine. Finally, the fragments
produced during the bromization of (OAr)4PcPb in 1,1,2-trichloroethane were characterized by GC/MS. Based on the electronic structure, the possible mechanism of decomposition
of these compounds was presented and discussed. |
