| 1. A method for fabricating an organic thin film transistor including a substrate, a gate electrode, a gate insulating layer,
metal oxide source/drain electrodes and an organic semiconductor layer, the method comprising:
treating at least one surface of the metal oxide source/drain electrodes with a self-assembled monolayer (SAM) forming compound
containing a sulfonic acid group, wherein the self-assembled monolayer forming compound containing a sulfonic acid group is
represented by any one of Formulae 4 to 7 below:
![]() wherein q is an integer from 1 to about 10,000, and x and y are each independently an integer from 0 to about 10;
![]() wherein r and s are integers satisfying the relations 0<r≤10,000 and 0≤s<10,000, respectively, and w and z are each independently
an integer from 0 to about 20;
![]() wherein t and u are integers satisfying the relations 0<t≤10,000 and 0≤u<10,000, respectively, and v and c are each independently
an integer of from 0 to about 20;
![]() wherein d and e are integers satisfying the relations 0<d≤10,000 and 0≤e<10,000, respectively, and
wherein f is an integer from 0 to about 20.
