Abstract
Various apparatuses, systems and methods involve high mobility materials. In accordance with one or more example embodiments, a material includes a conjugated molecule and a side chain bonded to the conjugated molecule. The side chain includes at least one of a siloxane-terminated unit and a derivative of a siloxane-terminated unit that enhance solubility of the conjugated molecule. Further, the side chain facilitates a π-stacking distance between the conjugated molecules when stacked (e.g., in an organic semiconductor film), thereby facilitating carrier mobility between the conjugated molecules
Claims24
A material comprising:
- conjugated molecules;
- and
- for each conjugated molecule, a side chain bonded to the conjugated molecule and including at least one of a siloxane-terminated unit and a derivative of a siloxane-terminated unit configured and arranged to enhance solubility of the conjugated molecule and to set a π-stacking distance between the conjugated molecules that facilitates carrier mobility between the conjugated molecules.
An apparatus comprising:
- first and second conductive terminals;
- and
- an organic semiconductor film electrically coupled to pass carriers between the conductive terminals and including
- a plurality of conjugated molecules, and
- for each of the conjugated molecules, a side chain bonded to the conjugated molecule and including at least one of a siloxane-terminated unit and a derivative of a siloxane-terminated unit configured and arranged to enhance solubility of the conjugated molecule and set a π-stacking distance between the conjugated molecules in the organic semiconductor film, thereby facilitating carrier mobility between the conjugated molecules.
A material comprising a solubilizing side chain including a linear aliphatic chain and a siloxane-terminated unit including:
A method comprising:
- bonding solubilizing side chains to conjugated molecules, each side chain including at least one of a siloxane-terminated unit and a derivative of a siloxane-terminated unit;
- and
- forming a solution in a solvent by using the solubilizing side chains to increase solubility of the conjugated molecules in the solvent.
