Dual-Emissive Langmuir–Blodgett Films of a 9,9-Bis(4-ethynylphenyl)fluorene Derivative of Gold(I) and Some Europium-Substituted Polyoxometalates: Preparation, Characterization and Photoelectric Properties

Light-Emitting Self-Assembled Materials Based on d8 and d10 Transition Metal Complexes

“…941 By changing the bridging carbazole bis-alkynyl ligand into a 9,9-bis(4ethynylphenyl)fluorene ligand, luminescent LB films with near-white emission have been obtained because of the dual emissive nature of the hybrid material. 942 On the other hand, the gold(I) complex, [Au 2 (dppp)-(BIT) 2 ]•(CF 3 CO 2 ) 2 (dppp = bis(diphenylphosphino)propane; BIT = 2-benzimidazolethiol), was found to readily interconvert between two forms (Figure 208). 943 The discrete dinuclear complex was found to exhibit intramolecular aurophilic interactions with a Au(I)•••Au(I) distance of 3.1312(5) Å.…”

“…The presence of POM would lead to a certain degree of quenching of the luminescence of the alkynylgold­(I) complex, and the [Au]/POM hybrid films were observed to show a strong photovoltage effect in the UV–visible region . By changing the bridging carbazole bis-alkynyl ligand into a 9,9-bis­(4-ethynylphenyl)­fluorene ligand, luminescent LB films with near-white emission have been obtained because of the dual emissive nature of the hybrid material …”

Aggregation induced emission of gold(i) complexes in water or water mixtures

“…This concept has been widely used and there are numerous examples of a variety of applications for AIE materials. [16][17][18][19][20] Most of the AIE active molecules in literature are organic and this phenomenon has been less explored for metal complexes. Similar to organic compounds, TMC also exhibit rich optical and luminescent properties usually associated with metal centers and their stability in common organic solvents.…”

Ultra-thin films of amphiphilic lanthanide complexes: multi-colour emission from molecular monolayers

“…14,16,19 To translate into functional materials, it is desirable to immobilise Ln 3+ multiemissive species onto surfaces, however only limited examples exist of surface immobilised multi-emissive species. 5,15,16,[19][20][21][22][23][24][25] Langmuir-Blodgett (LB) deposition is promising technique for preparing multi-emissive lanthanide-based thin-films, 26,27 as it allows for multiple discrete amphiphilic species to be selfassembled into layers -either through sequential building up of layers of different species (multi-layered approach), or through mixing different amphiphiles together prior to deposition (mixed amphiphile approach). 22,28 Additionally, LB also gives reproducible deposition, and control over film thickness and shape.…”
