1. Abstract
We observed the change of absorption spectrum according to the polarity of solvents. Our experimental result shows that the change of polarity in the solute/solvent has the hypsochromic shift(blue shift) and bathochromic shift(red shift)
2. Introduction
Solvent effects occur because of solute-solvent interaction. Solute-solvent interaction is to following that : Intermolecular forces (van der Waals forces) are those which can occur between closed-shell molecules.
*A variety of Intermolecular forces
①Dipole-Dipole Forces : Directional forces depend on the electrostatic interaction between molecules possessing a permanent dipole moment μ due to their unsymmetrical charge distribution.

All of Alq3 / Rubrene are heterocyclic compounds. Due to fact that Rubrene has more double bond in comparison the Alq3, Rubrene have the effect of conjugation. As a result, the absorption peak of Rubrene moves to the right.
5. Summary
In summary, first, the band gap (2.86 eV) of Alq3 is larger than the band gap (2.27 eV) of Rubrene. Second, we can know approximately n→π* or π→π* transition from the ε of Alq3/ Rubrene. Finally, by using the band gap properties of various organic materials, it will help to design the OLED.
