A new series of optoelectronic nanocomposites: CMI-1 mesoporous core/ZnS shell

SBA-15 mesoporous silica coated with macrocyclic calix[4]arene derivatives: Solid extraction phases for heavy transition metal ions

“…Grafting method consists of reaction of a suitable organosilane with surface silanol groups using an appropriate solvent under reflux conditions [7], where its most apparent advantage is to well preserve the mesostructure after post-modification [9,10]. Actually, many of these investigations have utilized periodic mesoporous silicas, including HMS, MCM-41, MCM-48, SBA-15 or CMI-1 as the inorganic matrix [7,[11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. Among them, SBA-15 materials show attractive properties due to its large pore size (from 10 nm to over 30 nm) and improved thermal and hydrothermal stability.…”

Monodisperse crystalline semiconducting ZnS hollow microspheres by a new versatile core-shell strategy

“…57,58 The functionalization of CMI-1 material was carried out as described elsewhere. [59][60][61][62][63][64] The silanol groups at the surface of the CMI-1 material were reacted firstly with chloromethyltriethoxysilane in dry toluene at 110 C under inert atmosphere. Afterwards ethylenediamine molecules were introduced into the system to complete the functionalization process.…”

“…Our previous work showed that this process led to an excellent grafting of hSiCH 2 Cl groups onto the surface of mesoporous silica. [59][60][61][62][63][64] A further reaction of the hSiCH 2 Cl group with ethylenediamine to form hSiCH 2 -NHCH 2 CH 2 NH 2 is quite efficient. [59][60][61][62][63][64] The ZnS shell was synthesized by a two step method described as follows: the surface-modified mesoporous CMI-1 silica spheres were suspended in a solution of Zn(CH 3 COO) 2 $2 H 2 O (0.1 M) for one hour.…”

Smectogenic liquid crystals and nanoparticles: an approach for potential application in photovoltaics

“…[2][3][4] They can show improvements in mechanical, 5 optical, 6 magnetic, 7 electrical 8 and optoelectronic 9 properties of the original arrays. Some examples are ceramic semiconductor nanocrystals incorporated into polymer matrices.…”

“…A nanocomposite is a binary combination of at least one (in)organic or polymeric material mixed with nano-sized domains of a solid, 1 which has attracted great interest and has been widely explored recently. [2][3][4] It can show improvements in mechanical, 5 optical, 6 magnetic, 7 electrical 8 and optoelectronic 9 properties of the original arrays. Some examples are ceramic semiconductor nanocrystals incorporated into polymer matrices.…”
