在超声膨胀条件下，利用脉冲放电产生了三（8-羟基喹啉）铝（Alq 3）分子阴离子，并经质量选择后记录了其光电子能谱。测得Alq ~（3-）的垂直脱离能和绝热电子亲合能分别为1.24 ± 0.01和0.89 ± 0.04eV。利用这些能量，估算了Alq 3体相分子间电子输运的重组能为0.70 ± 0.08eV。
A molecular anion of tris(8-hydroxyquinolinato)aluminum (Alq3) was generated by a pulsed discharge to the solid sample under supersonic expansion and its photoelectron spectrum was recorded after mass selection. The vertical detachment energy of Alq3–and the adiabatic electron affinity of Alq3were determined to be 1.24 ± 0.01 and 0.89 ± 0.04 eV, respectively. By using these energies determined for monomeric Alq3, the reorganization energy for the intermolecular electron transport in bulk Alq3was estimated to be 0.70 ± 0.08 eV.
