Synthesis and Pd(II) binding studies of octasubstituted alkyl thio derivatised phthalocyanines
摘要:
Synthesis and characterization of non-peripherally (4,5) and peripherally (6,7) substituted metal free and Pd octapentylthiophthalocyanine and coordination of palladium ions to these Pcs are reported. The unmetalated complexes (4 and 6) show Id coordination at the central metal and at the ring. The number of Id ions bound to complex 4 were found to be five and to complex 6 were three. The equilibrium constant for the binding of Pd to complexes 4 was lower (K = 1.2 x 10(9) dm(3) Mol(-1)) than for complex 6 (K = 5.7 x 10(10) dm(3) mol(-1)). (C) 2009 Elsevier Ltd. All rights reserved.
