On the other hand, pyrazoline and pyrazole derivatives are successfully used for material science tasks. For example, triarylpyrazolines are used in the synthesis of green electroluminescent polymers for light-emitting diodes [18], Some aromatic substituted 2-pyrazolines are effective organic luminophores [19,20], fluorophores [21] and scintillating materials [20, 22].

In this article, we review the most recent research on such issues as the design and synthesis of novel electroluminescent polymers with high electron affinity, and of polymeric oxadiazoles with a strong tendency for n-doping, as well as those having high photoluminescence efficiency. Although most of this work was done in our latoratory, other important work is also included. 

V and 1 GHz, respectively. A ne v nonconjugated polymer electroluminescent material, including stilbene derivatives, vas patented [19]. The preparation process for this electroluminescent material involved monomer synthesis and polymer synthesis. The author suggested that this electroluminescent material can be used in electroluminescent devices, luminescent devices, and so on. 

Organic polymers that emit light on the imposition of an electric field have commanded increasing attention in the last decade both for their scientific interest and as potential materials for electrooptical and optoelectronic applications. A number of reviews on electroluminescent polymers focusing the basic physics [1-5], synthesis and properties [6,7], device operation and materials [8-11], design and synthesis [12] blue emitting structures [13] have been published. Some books are also out on the subject [14—18].

The synthesis-driven approach towards material science can be applied to create oligomers and polymers with optimized properties, e.g. maximized carrier mobilities and electrical conductivities or high photo- and electroluminescence quantum yields. It becomes obvious, however, that the ability to synthesize structurally defined -architectures is the key to these high performance materials. 

Optically active polymers are potentially very useful in areas such as asymmetric catalysis, nonlinear optics, polarized photo and electroluminescence, and enantioselective separation and sensing.26 Transition metal coupling polymerization has also been applied to the synthesis of these polymers.27 For example, from the Ni(II)-catalyzed polymerization, a regioregular head-to-tail polymer 32 was obtained (Scheme 9.17).28 This polymer is optically active because of the optically active chiral side chains.
