MCD measurements were made with a JASCO J-725 spectrodichrometer equipped with a JASCO electromagnet that produced magnetic fields of up to 1.09 T with parallel and then antiparallel fields. Dichloromethane was used as solvent for all measurements.

The naphthalene analogue of Ti(Pc)(BP), i.e., (2,2′-binaphthyldioxy)-(tetra-tert-butylphthalocyaninato)titanium(IV), Ti(Pc)(BP), was similarly obtained using 2,2′-binaphthol in place of 2,2′-biphenol in the preparation of Ti(Pc)(BP). Ti(Pc)(BN) showed two intense absorption bands at 700 and 726 nm. The electronic and MCD spectral features of Ti(Pc)(BN) are similar to those of Ti(Pc)(BP).
