The synthesis and photophysical properties of the complex Fe(phen)(2)(TTF-dppz) (TTF-dppz = 4',5'-bis-(propylthio)tetrathiafulvenyl[i]dipyrido[3,2-a:2',3'-c]phenazine, phen = 1,10-phenanthroline) are described. In this complex, excitation into the metal-ligand charge transfer bands results in the population of a high-spin state of iron(II), with a decay lifetime of approximately 1.5 ns, in dichloromethane, at room temperature. An intraligand charge transfer state can also be obtained and has a lifetime of 38 ps. A mechanism for the different states reached is proposed based on transient absorption spectroscopy.
该文描述了配合物Fe(phen)(2)(TTF-dppz)（TTF-dppz = 4',5'-双（丙基硫代）四噻吩富烯[i]二吡啶并[3,2-a:2',3'-c]吩嗪，phen = 1,10-菲咯啉）的合成及光物理性质。在该配合物中，在室温下的二氯甲烷中，将激发能转移到金属-配体电荷转移带中，会导致铁（II）的高自旋态的形成，其衰减寿命约为 1.5 ns。也可以得到一个配体内电荷转移态，其寿命为 38 ps。基于瞬态吸收光谱，提出了一种达到不同状态的机制。
