2-Step励起エネルギー移動を利用したペンタセンのレーザー脱離イオン化質量分析法

抄録

Laser desorption/ionization mass spectrometry was performed to one of polycyclic aromatic hydrocarbons (PAHs), pentacene (Pen), doped in mixed crystals of anthracene (Ant) and tetracene (Tet). By changing the mixing ratio of molecules, it was understood that Pen was ionized efficiently by 2-step excitation energy transfer among three molecules when the molar amount of Pen was more than –10 times larger than that of Tet. Possible mechanism of energy transfer was discussed.
