Conductive metal-organic frameworks, known as metal-organic graphene (MOG) analogues, share structural similarities to graphene and hold much promise for electronic applications [1]. However, to be industrially relevant, these MOGs must be interfaced as coatings onto solid supports with precise control over fabrication conditions. Recent work [2] has demonstrated the formation of a MOG coating of Ni3(HITP)2 via the air-liquid interface method, but no work exists on more well-controlled methods. In this study, we successfully demonstrate the fabrication of Ni3(HITP)2, film by liquid phase epitaxy (LPE). Since LPE involves an automated liquid phase approach, metal and organic components are introduced stepwise to form a coating on substrates. The resulting coatings are crystalline, porous, and conductive. Interestingly, Raman spectra of these coatings share similar features to that of graphene. Future work will focus on improving the uniformity of these films, which will be critical for implementation of MOGs into electronics.
