摘要
德国科学家Friedrich W(o|¨)hler在1844年发现了第一个分子"共晶"——醌氢醌,129年后L.B.Coleman和A.J.Heeger等人报道了TTF-TCNQ电荷转移复合物晶体存在类金属导电性。这时人们才意识到,研究共晶这种特殊的固体材料,能够发现意想不到的、令人振奋的新性质和新现象。因此,两种或多种材料共结晶不仅能够实现材料的多功能化("1+1=2"),还可以探索和发现单组份材料所不具有的新现象和新性质("1+1≠2")。在本报告中,我们采用实验和理论计算等手段,揭示了给受体分子共晶中的电荷转移作用,研究基态和激发态下与电荷转移相关的振动光谱、顺磁性和光物理特性,并着重发展其在电子学、光子学、非线性光学和光电转化等方面的新应用。
Molecular cocrystal,formed with two or more different compounds in a stoichiometric ratio,exhibits unpredicted and versatile chemicophysical properties based on the multi-component synergistic and collective effects( "1+1≧2").Co-crystallization therefore offers an alternative approach for achieving multifunctional materials and an ideal research platform for exploring new chemicophysical phenomena.Herein,the CT nature of ground and excited states of cocrystals were confirmed by experimental techniques and theoretical calculations,while their electronic,photonic,nonlinear optic and photovoltaic properties were investigated.
