Synthesis, Characterization and Optical Limiting Properties of Novel Ball-Type Four Tert-Butylcalix[4]Arene Bridged Double-Decker Lutetium(III) and Indium(III) Phthalocyanines

Abstract

Novel ball type four tert-butylcalix[4]arene bridged double-decker lutetium(III) phthalocyanine [LuPc2(tbca)4] 2 which exhibit nonlinear optical limiting behaviour and indium(III) phthalocyanine [InPc2(tbca)4] 3 were prepared by the reaction of 1,3-bis(3,4-dicyanophenoxy)-4-tert-butylcalix[4]arene 1 and the corresponding metal salts (Lu(OAc)3·3H2O and InCl3) in the presence of lithium metal in 1-pentanol. Newly synthesized phthalocyanines were characterized by elemental analysis, UV-vis, IR, MALDI-TOF MS and 1H NMR spectra.
