An important and fascinating feature of molecular charge transfer (CT) material is almost unlimited possibility to tune their properties by virtue of the coupled electronic and structural change of molecular state. The very recent progress in the study on electronic-structural transformations in CT molecular systems has stressed the importance of cooperativity. This opens the way for controlling the switching by external field (electric, magnetic, light, etc.) between different molecular states, i.e. control of nano-scale phase domains by virtue of cooperative interactions. We demonstrated that various systems shows photoinduced phase transitions accompanied with the changes in magnetic, transport, optical, dielectric properties and structural changes. We also demonstrated that the dynamics and kinetics of the phase transformation, i.e. dynamical behavior of nano-scale phase domains in this class of material is important not only for materials science and its application but also for the basic research on the (nonequilibrium) statistical physics and chemistry.

分子电荷转移（CT）材料的一个重要而有趣的特征几乎是通过分子状态的耦合电子和结构变化来调整其性能的可能性。 CT分子系统中电子结构转化研究的最新进展强调了协作的重要性。这为不同分子状态之间的外部场（电气，磁性，光等）控制开关开辟了道路，即通过合作相互作用来控制纳米级相域。我们证明了各种系统显示了光诱导的相变，并伴随着磁，传输，光学，介电特性和结构变化的变化。我们还证明了相变的动力学和动力学，即此类材料中纳米级相域的动力学行为，不仅对材料科学及其应用，而且对（非平衡）统计物理和化学的基础研究也很重要。
