at the peripheral positions of the [CuPc]2 framework, where [CuPc] units are linked by a common
annulated benzene ring to give the planar dinuclear structure, was prepared and characterized. The
introduced bulky 2,6-dimethylphenoxyl groups were revealed to effectively suppress the aggregation
of the dinuclear complex in the toluene solution, showing a considerably red-shifted Q-band at 838 nm.
The EPR spectrum (measured in the frozen toluene solution at 15 K) and temperature-dependent
magnetic moment indicated the existence of antiferromagnetic interaction between the copper(II) ions.
The exchange integral J was estimated to be -1.8 cm-1 using Bleaney Bowers equation for the S1 = S2 =
1/2 system. The long-range interaction (Cu–Cu distance = 10.7 Å) through the common annulated
benzene ring between two [CuPc] units was confirmed by the DFT calculation result.英語フィールド
