Red-NIR luminescence of Mo₆ monolayered assembly directly anchored on Au(001)

Abstract

The designed cluster [Mo6Bri8(NCS)a6]2− retains its multicomponent near infrared emission despite being in direct contact with a crystalline gold surface.

Surface Plasmon Tunability of Core–Shell Au@Mo6 Nanoparticles by Shell Thickness Modification

“…The starting cluster precursor (NH 4 ) 2 [Mo 6 Br i 8 (NCS) a 6 ] was prepared from the ternary bromide Cs 2 [Mo 6 Br i 8 Br a 6 ] by interaction with NH 4 NCS in a H 2 O:EtOH mixture (50:50). 20,23 Core-shell Au@Mo 6 nanoparticles were synthesized by the controlled addition of a solution of [Mo 6 Br i 8 (NCS) a 6 ] 2-(62μmol in EtOH) onto an aqueous solution of citrate capped AuNP (OD 0.5), and let to rest under mechanical agitation for 24h. The size of the amorphous shells was adjusted as a function of Mo 6 cluster concentration and time.…”

“…The pendant S atoms exhibit a high affinity to Au. 23 The optical response of the nanoparticles can also be excited by plane-wave far-field illumination, and a comparison is given between their response to a plane wave and an electron beam excitation. Our results provide further proof for the versatility of these structures.…”

From supramolecular to solid state chemistry: crystal engineering of luminescent materials by trapping molecular clusters in an aluminium-based host matrix

“…Then, the self-assembling of building blocks to form the target material will be driven by a supramolecular organic linker, such as cyclodextrins as demonstrated earlier in CLUSPOM compounds. 9 the elaboration of hybrid nano-materials [30][31][32][33][34][35] and functional surfaces 36,37 . In particular, they i) absorb light continuously from UV to visible, ii) emit continuously from red to NIR region through several excited emissive states, iii) are able to photoinduce singlet oxygen generation, iv) exhibit interesting catalytic and photo-catalytic properties.…”

Evidence of the Ambipolar Behavior of Mo6 Cluster Iodides in All-Inorganic Solar Cells: A New Example of Nanoarchitectonic Concept

“…This is not the case here for the molecular MC-based photoelectrodes where the photo-oxidation and and reported for monolayers of [{Mo 6 Br i 8 }(NCS) a 2 ] 2deposited on gold surfaces. 33 This probably originates from the confinement of electrons within the nanosized metallic molecular clusters.…”
