Controlled Self-Assembly and Photo-Thermal Activation of Viologen-Based 2D Semiconductors for Dual-Function Energy Management in All-Weather Applications.

ABSTRACT: Solar thermal technology offers a promising solution to water scarcity; however, the continuous operation of solar evaporators remains challenging due to sunlight's intermittent availability. Herein, an alternative strategy is proposed to achieve dual-functional energy management of photo-thermoactivated viologen T semiconductors for enhanced solar water evaporation, water-enabled electricity generation, and electrothermal evaporation. A sequential cyanide-bridged layer-directed intercalation approach is developed, where infinitely π-stacked, redox-active N-methyl bipyridinium cations with near-planar structures are sandwiched between cyanide-bridged Mn^II-Fe^III. The extended absorption range of 95% is achieved through radical-π interactions that occur within the conti
