AB  - Two-dimensional van der Waals heterostructures are of considerable interest for 
      the next generation nanoelectronics because of their unique interlayer coupling 
      and optoelectronic properties. Here, we report a modified Langmuir-Blodgett 
      method to organize two-dimensional molecular charge transfer crystals into 
      arbitrarily and vertically stacked heterostructures, consisting of 
      bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF)/C(60) and 
      poly(3-dodecylthiophene-2,5-diyl) (P3DDT)/C(60) nanosheets. A strong and 
      anisotropic interfacial coupling between the charge transfer pairs is 
      demonstrated. The van der Waals heterostructures exhibit pressure dependent 
      sensitivity with a high piezoresistance coefficient of -4.4 x 10(-6) Pa(-1), and 
      conductance and capacitance tunable by external stimuli (ferroelectric field and 
      magnetic field). Density functional theory calculations confirm charge transfer 
      between the n-orbitals of the S atoms in BEDT-TTF of the BEDT-TTF/C(60) layer and 
      the pi* orbitals of C atoms in C(60) of the P3DDT/C(60) layer contribute to the 
      inter-complex CT. The two-dimensional molecular van der Waals heterostructures 
      with tunable optical-electronic-magnetic coupling properties are promising for 
      flexible electronic applications.Two-dimensional van der Waals heterostructures 
      are of interest due to their unique interlayer coupling and optoelectronic 
      properties. Here authors develop a Langmuir-Blodgett method to organize charge 
      transfer molecular heterostructures with externally tunable conductance and 
      capacitance and broadband photoresponse.
