Recent advancements in organometallic 2D nanosheets have captured attention in optoelectronics, particularly for their ability to be processed in solution, yet their application is limited by the stability of organic components.
A new air-stable 2D nanosheet, bis(dithiolene)iron(II) (FeBHT), has been developed using a special polymerization method that protects sensitive sulfur groups, enhancing durability against oxidation.
The FeBHT exhibits impressive photoresponse characteristics and maintains over 94% of its original performance even after 60 days in air, suggesting strong potential for practical applications in optoelectronic devices.
