Abstract

Polymeric one-dimensional (1D) triazole-based Fe^II spin crossover nanoparticles have been entrapped in pluronic P123 matrix, forming nanorods in which the interaction between host (P123) and guest (Fe^II complex) promoted high reproducibility of the spin crossover process, significant shifts of the transition temperatures (T↑=370 K, T↓=338 K for the P123 entrapped material vs the literature values of T↑=358 K, T↓=341 K for the neat/polymer free system) and larger magnetic hysteresis width.

Keywords: 1D coordination polymer; density functional calculations; organic-inorganic hybrid composites; spin crossover.
