The tuning of quantum magnetization for organic/inorganic hybrid materials composed of Mn12-acetate and azobenzene casted into PMMA films on PVA films

Computational Treatments of Hybrid Dye Materials of Azobenzene and Chiral Schiff Base Metal Complexes

“…This results in the intermolecular interactions decreasing the order and the aggregation in restricted environment (free volume) of PMMA films, which will be discussed with MD molecular modeling in a later section. It is examined that photoisomerization of AZ from trans-form to cis-form also resulted in slight increasing of magnetization [24][25][26]. The ∆M value increases smoothly to a maximum value at 6.8 K, and then decreases sharply and reaches a minimum value at 2.1 K. The behavior supported the appropriate formation of hybrid materials, in other words, suitable dispersion and intermolecular interaction among the solutes.…”

“…For about a decade, we have systematically investigated photofunctional organic/inorganic hybrid materials containing photochromic organic dyes, such as azobenzene (AZ) [7][8][9][10][11], disperse red 1 [11], spiropyran [12,13], and inorganic metal complexes, such as (chiral) Schiff base [14][15][16][17][18] (especially related to salen-type [19][20][21][22]) or other magnetic complexes [23][24][25][26][27]. To form hybrid systems in the solid state, in addition, polymer matrix, e.g., polymethyl methacrylate (PMMA) or polyvinyl alcohol (PVA) [23,28], were also employed.…”
