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. © ISUCT Publishing.
