A new monophthalocyaninato ytterbium(iii) complex 5 with eight 3,5-di-t-butylphenoxyl substituents at peripheral positions is synthesized. X-ray structural analysis of 5·CHCl3·MeOH reveals that the Yb3+ ion is seven-coordinate, surrounded by four nitrogen atoms from the phthalocyaninate dianion and three oxygen atoms from the anionic tripodal LOMe- ligand {LOMe- = [(cyclopentadienyl)tris(dimethylphosphito) cobaltate(iii)]}. The effects of substituents on the relative singlet oxygen (1O2) quantum yields of monophthalocyaninato ytterbium(iii) complexes are investigated through comparison. It is found that the monophthalocyaninato ytterbium(iii) complex has higher 1O2 quantum yield than its corresponding phthalocyaninate ligand. The introduction of a 3,5-di-t-butylphenoxy substituent on the microcycle can enhance the yield of singlet oxygen. Due to the heavy-atoms of both iodine and lanthanide ions, the ytterbium(iii) complex 4 based on tert-butyl and iodine substituted phthalocyanine ligands has the highest 1O2 quantum yield (0.82).

Phthalocyanines solubilised by either 8 or 16 aryloxy or haloaryloxy groups are described. A series of phthalocyanine derivatives were prepared containing indium. 1,2-Dinitriles and the corresponding diiminoisoindolines were used as precursors. A naphthalocyanine metallated with indium and solubilised with four tert-butyl groups is reported.
