A monomeric bowl-like pyrogallol[4]arene Ti12 coordination complex†
Abstract
Herein, an unprecedented monomeric bowl-like coordination complex, Ti12PgC3 (PgC3 = C-propylpyrogallol[4]arene), has been successfully synthesized. To the best of our knowledge, Ti12PgC3 not only presents the first pyrogallol[4]arene-based titanium coordination complex, but also the highest nuclearity titanium coordination complex in the metal–calixarene system. In addition, this titanium coordination complex can effectively degrade the methylene blue (MB) dye under sunlight.
