摘要：

The receptor properties of complexes of 5,10,15,20-tetraphenyl-21,22,23-trimethylporphyrin and 5,10,15,20-tetraphenyl-2,3,7,8,12,13,17,18,21,22,23,24-dodecamethylporphyrin toward hydroxide ion were explored by the method of spectrophotometric titration in methanol with iodine and triflate respectively. We found that in the studied complexes the hydroxide ion is replaced by the respective counterion that leads to a strong response in the visible region of absorption spectrum. The formation constants and the concentration ranges of existence of the complexes were determined.
