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）材料的一个重要且令人着迷的特征是，通过耦合的电子和分子状态的结构变化来调节其特性几乎是无限的。 CT分子系统电子结构转变研究的最新进展强调了协同性的重要性。这为通过外场（电、磁、光等）控制不同分子状态之间的切换开辟了道路，即通过协作相互作用控制纳米级相域。我们证明了各种系统表现出光致相变，并伴随着磁性、传输、光学、介电性质和结构变化的变化。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于材料科学及其应用很重要，而且对于（非平衡）统计物理的基础研究也很重要和化学。
