Electronic devices with organic nanoparticles

A method of making an organic field effect transistor, comprising:

• mixing a first solvent solution containing perylene with a second solvent solution containing tetracyanoquinodimethane to obtain perylene-tetracyanoquinodimethane nanoparticles, the mixing being performed in a third non-solvent solution in which neither perylene nor tetracyanoquinodimethane are soluble, resulting in a fourth solution;
• lyophilizing the fourth solution to remove the fourth solution from the perylene-tetracyanoquinodimethane nanoparticles;
• catching perylene-tetracyanoquinodimethane nanoparticles ejected during lyophilization of the fourth solution with a covering, the covering comprising a first film layer comprising holes and a second film layer to catch nanoparticles ejected during outgas sing of the nanoparticles;
• providing a semiconductor substrate having an insulating layer thereon;
• depositing a source electrode and a drain electrode onto the insulating layer such that the source electrode and the drain electrode define a channel region therebetween;
• and
• depositing an organic semiconductor layer in the channel region by spin coating a mixture comprising a liquid polymer and an organic semiconductor onto the semiconductor substrate, the organic semiconductor comprising an organic charge transfer complex including multicomponent organic nanoparticles, the multicomponent organic nanoparticles comprising perylene-tetracyanoquinodimethane nanoparticles obtained in the lyophilizing step;
• and
• drying the spin-coated mixture to form a film comprising perylene-tetracyanoquinodimethane nanoparticles embedded in a polymer matrix.
