A tetraphenylethylene (TPE)-based flexible imidazolium (L) salt was used to develop a di-nuclear silver(I)–tetracarbene (1) complex. Coordination-induced rigidity upon formation of 1 exhibited a 6-fold increase in emission intensity in acetonitrile compared to starting L. Despite TPE being a well-known aggregation-induced emissive moiety, Ag^I–N-heterocyclic carbene (NHC) complex 1 had a remarkably higher fluorescence emission (4-fold) in dilute solution when compared with L in its aggregated state. Finally, this enhanced emission was used to institute a new platform for an artificial light-harvesting system. 1 acted as an energy donor and efficiently transferred energy to Eosin Y (ESY) with a high saturation at a 67:1 (1/ESY) molar ratio. Use of rigidification-induced emission of the Ag^I–NHC complex to fabricate a light-harvesting scaffold is a new approach and can greatly impact the generation of smart materials.

用于人工光采集的刚性诱导发射金属-卡宾配合物

基于四苯乙烯 (TPE) 的柔性咪唑鎓 ( L ) 盐被用来开发双核银 (I)-四卡宾 ( 1 ) 络合物。与起始L相比，在乙腈中形成1 时配位诱导的刚性表现出发射强度增加 6 倍。尽管 TPE 是众所周知的聚集诱导发射部分，但与聚集态的L相比， Ag ^I – N -杂环卡宾 (NHC) 配合物1在稀溶液中具有明显更高的荧光发射（4 倍）。最后，这种增强的发射被用来建立一个用于人工光采集系统的新平台。1作为能量供体，有效地将能量转移至高饱和度的曙红 Y ( ESY )，摩尔比为 67:1 ( 1/ESY )。利用 Ag ^I -NHC 复合物的刚性诱导发射来制造光捕获支架是一种新方法，可以极大地影响智能材料的产生。
