We shall study details ultrafast exciton and charge transfer state dynamics in organic crystals which have zero Coulomb coupling between molecules in the crystal stacks. These materials form a new sub set of organic matter and this project will yield important information. Techniques including ultrafast time correlated single photo counting fluorescence lifetime measurements will be made along with femtosecond photoinduced absorption. Triplet excited states will be investigated using nanosecond time gated measurements. Polarised emission studies of these highly anisotropic crystals will also be made. As a sub set of these materials, molecules reportedly showing negative singlet triplet gap will be examined.

我们将研究有机晶体中超快激子和电荷转移态动力学的细节，这些有机晶体在晶体堆叠中的分子之间具有零库仑耦合。这些材料形成了有机物的新子集，该项目将产生重要信息。包括超快时间相关单光计数荧光寿命测量在内的技术将与飞秒光诱导吸收一起进行。将使用纳秒时间选通测量来研究三重激发态。还将对这些高度各向异性晶体进行偏振发射研究。作为这些材料的子集，将检查据报道显示负单线态三线态间隙的分子。
