Organosulfonate Counteranions—A Trapped Coordination Polymer as a High‐Output Triboelectric Nanogenerator Material for Self‐Powered Anticorrosion.

Selection of the friction electrode materials is crucial to the performance of a triboelectric nanogenerator (TENG). In the present study, a metal–organic coordination complex containing organosulfonate counteranions with electron‐donating ability was synthesized through the coordination‐driven self‐assembly approach under mild reaction conditions and was chosen as a positive electrode material to construct a triboelectric nanogenerator, exhibiting high‐output performance with a peak value of short circuit current density of 98.6 μA and an output voltage of 1180 V. As a practical application, it was shown to light up 1488 commercial green LEDs and power an anticorrosion system device to protect metals from corrosion. [ABSTRACT FROM AUTHOR]
