## Abstract The protonation and complex formation of the new ligand 3,3โฒ, 5,5โฒโtetramethylโdipyrrometheneโ4,4โฒโdicarboxylate in aqueous solutions was investigated by alkalimetric titrations and spectrophotometric measurements (25ยฐ, I = 1 (KNO~3~)). The p__K__ values for the N๏ฃฟH groups are 8.03 and
