The physical properties, such as electric and optical properties, of metal-Schiff base complexes
have been widely investigated. However, their thermoelectric (TE) properties remain unreported.
This work presents Cu(II)-Schiff base complexes as promising materials for TE power
generation. Therefore, three Cu(II)-Schiff base complexes (namely, [Cu(C32H22N4O2)].3 2H2O,
[Cu(C23H17N4O7Br)], and [Cu(C27H22N4O8)].H2O) have been synthesized in nanosized scale.
The electric and TE properties have been studied and comprehensive discussions have been
presented to promote the nano-complexes (NCs) practical applications in the field of TE power
generation. The electrical measurements confirm that the NCs are semiconductors and the
electrical conduction process is governed by intermolecular and intramolecular transfer of the
charge carriers. The TE measurements reveal that the Cu(II)-Schiff base NCs are nondegenerate
P-type semiconductors. The measured Seebeck coefficient values were higher compared to the
values reported in previous works for other organic materials indicating that the complexes under
study are promising candidates for theremoelectric applications if the electrical conductivity
could be enhanced.
