Anion identification using silsesquioxane cages

Abstract

Anthracene-conjugated octameric silsesquioxane cages thermodynamically display intramolecular excimer formation, which can be used to identify anions through the change of fluorescence.

Stimuli‐Responsive Circularly Polarized Organic Ultralong Room Temperature Phosphorescence

“…In light of the unique features of the photo/thermal responsive reversible CP-OURTP emission of these purely organic materials,anew-concept integrated combinational logic [33,34] encryption device was designed and fabricated using S/R-COOCz,anormal yellow OURTP molecule (CPM), [25,35] ab lue fluorescent molecule (9-bromoanthracene), [36] and an inorganic phosphor (Figures 4b and S23-S25). [37] This integrated combinational logic encryption device contains one INHIBIT and one OR logic gate ( Figure S24).…”

“…Fourthly,t he photo-excitation results in strong aggregation coupling,which can effectively stabilize the triplet excitons to elongate their lifetime for CP-OURTP.F inally,t he photoactivated CP-OURTP can be deactivated to the pristine state by thermal treatment and the activation and deactivation cycle is highly reversible and stable (Figures 4a and S20). In light of the unique features of the photo/thermal responsive reversible CP-OURTP emission of these purely organic materials,anew-concept integrated combinational logic [33,34] encryption device was designed and fabricated using S/R-COOCz,anormal yellow OURTP molecule (CPM), [25,35] ab lue fluorescent molecule (9-bromoanthracene), [36] and an inorganic phosphor (Figures 4b and S23-S25).

Stimuli‐Responsive Circularly Polarized Organic Ultralong Room Temperature Phosphorescence

“…In light of the unique features of the photo/thermal responsive reversible CP‐OURTP emission of these purely organic materials, a new‐concept integrated combinational logic encryption device was designed and fabricated using S/R‐COOCz , a normal yellow OURTP molecule ( CPM ), a blue fluorescent molecule (9‐bromoanthracene), and an inorganic phosphor (Figures b and S23–S25) . This integrated combinational logic encryption device contains one INHIBIT and one OR logic gate (Figure S24).…”

A Selenone-Functionalized Polyhedral Oligomeric Silsesquioxane for Selective Detection and Adsorption of Hg2+ ions in Aqueous Solutions

“…Compared to conventional organic molecules and polymers, POSS and their derivatives (typically T 8 , R 8 Si 8 O 12 ) possess many unique characteristics, such as rigid, high symmetric, well-defined, and ideal inorganic-organic hybrid structures, nanoscopic size (1-3 nm) and high functionality, etc, and thus having intriguing advantages, such as high thermal stability, mechanical properties (e.g., strength, modulus, rigidity), and improved quantum yields [1][2][3][4][5][6][7][8]. By virtue of these merits, they have been widely applied in many fields, including drug delivery [9], wastewater treatment [10,11], chemical sensors [12][13][14][15][16], energy transfer [17], bioimaging [18], chromatography [19], Polymers 2019, 11,2084 2 of 16 polymer electrolytes [20], catalysis [21][22][23], and membranes [24], etc. To realize these applications, it is crucial to incorporate various functionality into the POSS derivatives and/or materials.…”

“…To realize these applications, it is crucial to incorporate various functionality into the POSS derivatives and/or materials. For example, Ervithayasuporn et al decorated anthracene groups on the peripheral surface of the octameric silsesquoxane cage, making the material exhibit anion identification and distinguish up to four ions (F -, OH -, CN -, PO 4 3-) [12]. Hong et al attached bis(diphenylphosphino)amine ligand to POSS, affording a solubility-enhancing material for catalytic ethylene trimerization and tetramerization [23].…”
