| 中文摘要 | this letter reports the experimental studies on electrical dipole-dipole interaction effects on magnetocurrent (mc) and magneto-electroluminescence (mfe(el)) based on two phosphorescent dyes: heavy-metal complex ir(ppy)(3) and ir(ppy)(2)(acac) with strong spin-orbital coupling but different electrical dipole moments. we find that the ir(ppy)(3) with strong electrical dipole moment shows negligible mc and mfe(el). however, the ir(ppy)(2)(acac) with weak dipole moment exhibits appreciable mc and mfe(el). the experimental results suggest that the electrical dipole-dipole interaction can change the mc and mfe(el) from capture-based regime, where charge carriers are captured through spin-dependent process at short distance, to intersystem crossing-based regime, where charge carriers are captured through spin random process at long distance. as a result, changing electrical dipole-dipole interaction presents a new pathway to tune magnetic field effects in organic semiconductors.
