While the electron intercalates and deintercalates easily due to the smaller energy that orbit leaps from the HOMO orbit to the LUMO orbit.
最高占有轨道(HOMO)到最低空轨道(LUMO)的跃迁能很小,电子较易进行嵌入和脱出。
Electrochemical analysis of these compounds was carried out, and by using cyclic voltammetry, we calculated the HOMO orbital energy levels, and further obtained the LUMO energy levels.
Compared to cyanoacrylic acid group, the(co) rhodanine acetic can also shift LUMO of dye positively and reduce the force of electron injection into conduction band of TiO2.
