Simultaneous non-covalent bi-functionalization of 1T-MoS2 ruled by electrostatic interactions: towards multi-responsive materials.

Dual functionalization of chemically exfoliated MoS2 has been achieved by exploiting coulombic interactions among positively charged molecules and the negatively charged 2D flakes. The reversibility and kinetics of the process have been studied by spectroscopic tools. The hybrid material has been transferred to various substrates, yielding multifunctional robust flexible films.
