Abstract

The use of MCM-41 led to the development of a silylated hybrid material (MS), which in turn played a crucial role in obtaining semiconducting polyphenylacetylene, with a conductivity of 8.13 × 10⁻⁵ S m⁻¹. MS was also responsible for reducing the polyphenylacetylene band gap from 2.13 eV to 1.83 eV. When used in a capacitor, polyphenylacetylene exhibited stability after 3000 charge/discharge cycles and a capacitance seven times higher than that of poly(o-methoxyaniline) (POMA) polymer.

期刊介绍： Catalysis Today focuses on the rapid publication of original invited papers devoted to currently important topics in catalysis and related subjects. The journal only publishes special issues (Proposing a Catalysis Today Special Issue), each of which is supervised by Guest Editors who recruit individual papers and oversee the peer review process. Catalysis Today offers researchers in the field of catalysis in-depth overviews of topical issues. Both fundamental and applied aspects of catalysis are covered. Subjects such as catalysis of immobilized organometallic and biocatalytic systems are welcome. Subjects related to catalysis such as experimental techniques, adsorption, process technology, synthesis, in situ characterization, computational, theoretical modeling, imaging and others are included if there is a clear relationship to catalysis.
