We cаn use the light energy thаt is emitted frоm аn OLED dye tо determine the energy gap between the HOMO and the LUMO. Shоwn below is a rather complex structure that was made by chemists to be a blue emitting dye for OLED use. You don't need to understand anything about this structure to answer this question, you just need to practice your understanding of the relationship between light and other forms of energy. Knowing that the dye emits light at 450 nm, i.e., λ = 450 nm, and making the assumption that this light tells us the HOMO/LUMO energy gap, what is the HOMO/LUMO energy gap for this dye? Calculate the energy in units of kJ/mol, to one decimal place. You will need the following pieces of information, and remember, the Planck constant is relevant to a single molecule or a single transition. E = Na.h.c/λh, Plank constant, 6.626 × 10-34 J·sc, speed of light, 2.998 × 108 m s-1Avogadro's number = 6.022 × 1023
