Porous silsesquioxane cage and porphyrin nanocomposites: sensing and adsorption for heavy metals and anions

Abstract

A porous silsesquioxane cage/porphyrin nanocomposite was designed as a dual fluorescent probe for the sensing and adsorption of both heavy metal ions and anions.

Progress in the self-assembly of organic/inorganic polyhedral oligomeric silsesquioxane (POSS) hybrids

“…Incorporating DDSQ or POSS into organic polymers to form self-assembled and ordered structures is also of interest when preparing porous organic/ inorganic microporous polymers (POIPs). [164][165][166][167] We have used Sonogashira-Hagihara coupling of DDSQBr with tetraphenylethene (TPE) and carbazole (Car) derivatives to append TPE and Car units, respectively, onto DDSQ moieties for the preparation of POIPs. These two POIPs exhibited high thermal stability, with a high char yield (ca.…”

Highly Selective Oxidation of Styrene to Styrene Oxide over a Tetraphenylporphyrin-Bridged Silsesquioxane-Based Hybrid Porous Polymer

“…47 The characteristic bands at 1465 and 968 cm −1 corresponded to the vibrational frequencies of C�N and porphyrin rings, respectively. 48 In addition, there were obvious changes in the position and intensity of the characteristic peak of C−H on the benzene ring. The deformation vibration of the benzene ring at 740− 680 cm −1 was obviously weakened, indicating the occurrence of multiple substitutions on the benzene ring.…”

The Use of the Thiol-Ene Addition Click Reaction in the Chemistry of Organosilicon Compounds: An Alternative or a Supplement to the Classical Hydrosilylation?

“…The functional POSS that are used most widely include pentacyclo-[9.5.1.1 3,9 .1 5,15 .1 7,13 ]-octasiloxane, 1,3,5,7,9,11,13,15-octaethenyl ( 1 ) [ 53 , 54 , 55 ] and pentacyclo-[9.5.1.13,9.15,15.17,13]-octasiloxane-1,3,5,7,9,11,13,15-octapropanethiol ( 2 ) [ 56 , 57 , 58 , 59 ] (see Figure 15 ).…”
