反应腔对铕-二氧化硫配合物亚稳态光激发的影响
Effects of the reaction cavity on metastable optical excitation in ruthenium-sulfur dioxide complexes
摘要：
本文报道了[Ru（SO_2）（NH_3）_4X]Y家族的两个新成员的光激发态晶体结构：1：X= H_2O，Y=（+/-）-对甲苯磺酸根_2; 2：X=异烟酰胺，Y=对甲苯磺酸根_2。激发态在100 K下是亚稳态的，在1中的光转换率为11.1（7）%，在2中的两个不同的位置上的光转换率分别为22.1（10）%和26.9（10）%.这一结果是相关的尝试，合理地设计相关的光激发系统的光学数据存储应用。
英文摘要：
We report photoexcited-state crystal structures for two new members of the [Ru(SO_2)(NH_3)_4X]Y family: 1:X=H2O, Y=(+/-)-camphorsulfonate_2; 2:X=isonicotinamide, Y=tosylate_2. The excited states are metastable at 100 K, with a photoconversion fraction of 11.1(7)% achieved in 1, and 22.1(10)% and 26.9(10)% at the two distinct sites in 2.We further show using solid-state density-functional-theory calculations that the excited-state geometries achieved are strongly influenced by the local crystal environment. This result is relevant to attempts to rationally design related photoexcitation systems for optical data-storage applications.
