A facile and low‐cost solution method is developed to fabricate large‐area organic 2D single crystals on a millimeter scale. The 2D crystals are prepared on arbitrary non‐crystalline substrates with thicknesses of a single molecular layer and perfect long‐range crystalline order. High‐performance OFETs are fabricated using the monolayer crystals as the semiconducting layer and the carrier mobility exhibits no thickness dependence, confirming the efficiency of the monolayer for charge transport.
