Resumen

[EN] 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 x 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.
