It was shown that photochemical and photophysical dynamics could be controlled by application of electric fields in various molecular systems. It was also shown that electrical conductivity of materials could be controlled by photoirradiation and application of electric fields. For example, insulator, metal and superconductor could be converted to each other in some organic conducting materials, and novel functions could be created as a result of photoinduced phase transition in the presence of electric fields. Intracellular function was also shown to be influenced by application of nanosecond pulsed electric fields, based on the fluorescence lifetime imaging spectroscopy.

结果表明，电场可以控制各种分子体系的光化学和光物理动力学。材料的电导率可以通过光照射和电场的作用来控制。例如，在一些有机导电材料中，绝缘体、金属和超导体可以相互转化，在电场存在的情况下，光诱导相变可以产生新的功能。基于荧光寿命成像光谱，细胞内功能也被证明受到纳秒脉冲电场的影响。
