摘要: We have prepared photomagnetic Langmuir–Blodgett films composed of an amphiphilic azobenzene and a magnetic polyoxometalate. The obtained film possesses well-organized layered structure where polyoxometalate anions are sandwiched by cations in single-layered manner. Reversible photoisomerization was achieved even at low temperature, accompanying intensity changes the d–d transition anions. effect observed reversibly upon alternate UV visible light irradiation. Based on polarized spectroscopy, is ascribed to structure-distortion layers.
