Özet

Alkylthio-tetrasubstituted mu-nitrido diiron phthalocyanine complexes are synthesized with n-butyl, iso-butyl, tert-butyl, and n-hexadecyl alkyl moieties. For the first time, a spectroelectrochemical investigation of mu-nitrido diiron phthalo-cyanines is achieved at all the redox steps. The complexes are stable in all their redox states, unlike their unsubstituted analogues. The interest of the present complexes is to prepare sensing devices by a solution processing method. Films are characterized by electronic absorption and Raman spectroscopies. Electrical measurements on resistors show the highly resistive behavior of these complexes, whatever the chain length. However, when combined with the lutetium bisphthalocyanine, an intrinsic semiconductor, these complexes form heterojunctions that exhibit a high sensitivity to ammonia, with a very good signal over noise ratio, at room temperature and under atmospheric conditions.
