“…[303] The use of a fully integrated HTT for primary and secondary screening as well as rapid polymer characterization was reported in 2003 and led to the discovery of Hf complexes for the polymerization of higher olefins. [303][304][305] Müllen and coworkers reported the development of a split&pool concept for the development of catalysts for olefin copolymerization reactions, where fluorescence microscopy was used to screen for the polymerization activity of immobilized Zr catalysts on silica beads tagged with rylene dyes. [306] A new family of Cr catalysts for ethylene polymerization was discovered by Maddox and co-workers using HTT.…”

There is increasing acceptance of high-throughput technologies for the discovery, development, and optimization of materials and catalysts in industry. Over the years, the relative synchronous development of technologies for parallel synthesis and characterization has been accompanied by developments in associated software and information technologies. This Review aims to provide a comprehensive overview on the state of the art of the field by selected examples. Technologies developed to aid research on complex materials are covered as well as databases, design of experiment, data-mining technologies, modeling approaches, and evolutionary strategies for development. Different methods for parallel synthesis provide single sample libraries, gradient libraries for electronic or optical materials, similar to polymers and catalysts, and products produced through formulation strategies. Many examples illustrate the variety of isolated solutions and document the barely recognized variety of new methods for the synthesis and analysis of almost any material. The Review ends with a summary of success stories and statements on still-present problems and future tasks.

“…These are the first late-transition-metal systems that control the microstructure of polyolefin. Powers et al applied the combinatorial concept into the catalytic systems mentioned the above [2,3]. Recently, group-IV and group-VI metal catalysts, as well as late-transitionmetal catalysts, have been studied using a combinatorial approach [3,4].…”

Combinatorial technology has been evaluated as the revolutionary approach to overcome the limitation of conventional research and to advance research in the development of novel materials and catalysts. For the past decade, because of the advance in library synthetic method and characterization tools, combinatorial and high-throughput methodology surprisingly matured and nowadays has been extended to discovering novel olefin polymerization catalysts. However, despite such an advance, the characterization methodology did not keep pace with the increase in library density and limited the application of combinatorial technology. Therefore, in combinatorial technologies, the development of novel characterization methods is urgent and very important. In this review, we introduce several characterization tools and synthetic apparatus that are currently applied to discovering inorganic materials and catalysts using combinatorial technology, and consider how to overcome these limitations.

“…Significant efforts have been made to immobilize metallocene catalysts on inorganic or polymeric materials. [11][12][13][14][15][16] For late transition metal catalysts, silica, [17][18][19][20][21][22][23][24] silica-alumina derivatives, [25][26][27] MgCl 2 , [28][29][30][31][32] and polymeric materials [33][34][35] were used as support in the preparation of supported catalysts. To the best of our knowledge, there is no report on supporting catalysts for vinyl polymerization of norbornene.…”

A series of nickel complexes, bis(salicylideneiminato)nickel(II), were supported on spherical MgCl 2 and SiO 2 . Scanning electron microscopy, energy-dispersed X-ray spectroscopy, and the BET method for surface areas measurements were utilized to examine the supporting process of the catalysts. The particle morphology of the original support is retained and replicated throughout the supported catalyst preparation and norbornene polymerization. Spherical polymer particle morphology was achieved, without reactor fouling.
