Abstract

A novel single-molecule magnet (SMM) of trans-substituted Tb(III) porphyrin, {[Tb(BIPPP)₂](DBU-H)} (BIPPP: 5,15-bis(3,5-isopentoxyphenyl)porphyrin, DBU: 1,8-diazabicyclo[5.4.0]undec-7-ene), is reported here. The alternating current magnetic susceptibility measurements showed the frequency dependence on the in-phase and out-of-phase magnetic susceptibility under both zero and 2000 Oe direct current magnetic fields. The barrier height for the reversal of the magnetic moment at the high-temperature region was estimated to be 299 cm^-1, which is the same order as that of the previously reported tetraphenylporphyrin-based Tb(III) double-decker complex. Atomic force microscopy revealed that {[Tb(BIPPP)₂](DBU-H)} formed self-assembled monolayers on highly oriented pyrolytic graphite using the simple drop-cast technique. The result proves the high design freedom of porphyrin-based double-decker SMMs. [DOI: 10.1380/ejssnt.2014.124]
