Selective and slow: The effects on the photophysics of a single salicylideneaniline molecule, induced by confinement in an all-organic, weakly interacting molecular capsule matching size, are studied time-resolved spectroscopy. acts efficiently to select only one deactivation pathway after photoexcitation keeps photochromism solid state with 300-fold retardation—relative solution state—in decay time photochromic product (see picture). Detailed facts importance specialist readers published as...
A new deep imidazoquinoxaline cavitand formed static helical alkane inclusion complexes by CH/pi stabilization of alkanes with the enlarged aromatic pi surfaces cavity inside.
Metal–organic frameworks have been extensively studied in catalysis owing to their unique physicochemical properties. However, this class of materials has not yet directly applied the catalytic ozonation organic pollutants. In study, MIL-100(Fe) was synthesized by a solvothermal method and characterized powder X-ray diffraction, thermogravimetric analysis, Fourier-transform infrared spectroscopy, N2 adsorption–desorption scanning electron microscopy. A range reaction conditions such as pH,...
Abstract A cavitand with acetamidoquinoxaline flaps self‐folds to form a deep confined cavity rigidified by intramolecular hydrogen bonding. The formed this compound is suitable for the selective encapsulation of cyclohexane. chair‐to‐chair interconversion encapsulated cyclohexane and free was investigated dynamic NMR spectroscopy in CDCl 3 at 400 MHz. Significant slowdown recorded due CH–π stabilization compared
The conjugated molecules based on pyrene and dithienopyrrole derivatives including 4-(2-ethylhexyl)-2-(pyren-1-yl)-4H-dithieno[3,2-b:2’,3’-d]pyrrole (EP4HP) 4-(2-ethylhexyl)- 2,6-di(pyren-1-yl)-4H-dithieno[3,2-b:2’,3’-d]pyrrole (EDP4HP) have been successfully synthesized via C–H direct arylation reaction. structures of these were determined nuclear magnetic resonance Fourier-transform infrared spectroscopy (FTIR). optical properties evaluated ultraviolet visible (UV-Vis) fluorescence...
Efficient syntheses of potentially valuable C 3 v -symmetric trindane-based triester scaffolds are reported. In the synthesis 2,5,8-tribenzyltrindane-2,5,8-tricarboxylate by benzylation corresponding treatment with lithium diisopropylamide in tetrahydrofuran, diastereoselectivity and yield cis,cis,cis- cis,trans,trans-isomers depended primarily on reaction temperature amount hexamethylphosphoramide used as additive. High diastereofacial selectivity was achieved at -90 °C cis,cis,cis-isomer...
In this work, two novel hyperbranched conjugated polymers poly(tris(4-(10-(2-ethylhexyl)-10H-phenoxazin-3-yl)phenyl)amine) (P1) and poly(tris(4-(7-(benzo[c][1,2,5]thiadiazol-4-yl)-10-(2-ethylhexyl)-10H-phenoxazin-3-yl)phenyl)amine) (P2) have been successfully synthesized via Direct polycondensation in the presence of Pd(OAc)2 as a catalyst. The chemical structures then were determined Fourier-transform infrared spectroscopy (FTIR) proton nuclear magnetic resonance (1H NMR). Subsequently,...
