英文摘要	By employing our nonradiative decay rate process coupled with time-dependent Density functional theory(DFT) calculation, we investigate theoretically the conjugation length effects on both the radiative and the non-radiative decay rates for diphenyl-polyenes. We find that the radiative transition rate constants hardly vary with the chain length because of the trade-off between the reduction of energy gap and the enhancement of oscillator strengths, but the non-radiative transition rate increases steadily indicating that the energy gap law governs.
