  Purely organic materials with negative and near-zero dielectric permittivity
can be easily fabricated. Here we develop a theory of nonlinear
non-steady-state organic plasmonics with strong laser pulses. The bistability
response of the electron-vibrational model of organic materials in the
condensed phase has been demonstrated. Non-steady-state organic plasmonics
enable us to obtain near-zero dielectric permittivity during a short time. We
have proposed to use non-steady-state organic plasmonics for the enhancement of
intersite dipolar energy-transfer interaction in the quantum dot wire that
influences on electron transport through nanojunctions. Such interactions can
compensate Coulomb repulsions for particular conditions. We propose the exciton
control of Coulomb blocking in the quantum dot wire based on the
non-steady-state near-zero dielectric permittivity of the organic host medium.
