Electronic Properties Of The Model Organometallic Polymer [M-C=C(N)]n (M = Cu(I), Ag(I), Au(I))

ABSTRACTThe organometallic complexes of transition metal M = Cu(I), Ag(I), Au(I) with d10 electronic configuration have interesting optical, electronic and magnetic properties. It is possible to prepare the high functional organometallic polymer materials by coordinating π-conjugated organic molecules with d10 metals. According to the experimental structures, the model polymers [M-C-C(N)]n are built up and quantum chemistry methods are used to calculate their properties. It is indicated from theoretical analysis that the organometallic polymers would have comparable conductivity when interactions exist between metals and π electrons of different chains.

Microstructures of the Fe 3 F 4 granular films doped by transition metal (TM) were analyzed and the phenomenological magnetoresistance theory was proposed in this paper. Influences of technological parameters including the temperature (T), the applied field (H) and the content (x) on the magnetoresistance (MR) are analyzed in detail. Through theoretical analysis, there are the following conclusions. Firstly, variations of MR with x are non-linear and MR may arrive at the maximum at a certain x. Secondly, MR decreases strongly with the increase of T, but the decreases may be reduced by doped TM. Then doped TM can help to improve electric and magnetic properties of half metals. Thirdly, MR increases with the increase of H when the magnetization of grains is unsaturated.

High potential of emission chemistry has been visualized in many fields, from sensors and imaging to displays. In general, conjugated polymers are the top rankers for such chemistry, despite the fact that they bring solubility problems, high expenses, toxicity and demanding synthesis. Metal-free polymeric semiconductor graphitic carbon nitride (g-CN) has been an attractive candidate for visible light-induced photocatalysis, and its emission properties have been optimized and explored recently. Herein, we present modified g-CN nanoparticles as organodispersible conjugated polymer materials to be utilized in a heterophase emission systems. The injection of a g-CN organic dispersion in aqueous polymer solution not only provides retention of the shape by Pickering stabilization of g-CN, but high intensity emission is also obtained. The heterophase all-liquid emission display can be further modified by the addition of simple conjugated organic molecules to the initial g-CN dispersion, which provides a platform for multicolor emission. We believe that such shape-tailored and stabilized liquid–liquid multicolor emission systems are intriguing for sensing, displays and photonics.
