Supramolecular organic photochemistry: control of covalent bond formation through noncovalent supramolecular interactions and magnetic effects.
Supramolecular organic photochemistry, a field concerned with the interaction of light with supramolecular assemblies of organic molecules, has been inspired by the remarkable structural and dynamic features of guest@host chemistry, particularly as exemplified by enzymes. Exemplars of supramolecular organic photochemistry from soft-matter hosts (micelles) and hard-matter hosts (porous solids) a...
متن کاملSpontaneous formation of organic helical architectures through dynamic covalent chemistry.
The spontaneous formation of organic helical structures, accompanied with an amplification of chirality, by dynamic covalent bonds between achiral and chiral building blocks is reported.

IR photodissociation (IRPD) spectra of [(N2O)nH2O] with n = 2–7 are measured in the 1100–3800 cm region. In parallel, the geometry optimization and the vibrational analysis are carried out at the B3LYP/6-311++G(d,p) level of theory. In the OH stretching (2400–3800 cm) region, the IRPD spectrum of the [(N2O)2H2O] ion shows a sharp band at 3452 cm and a broad one at around 2700 cm, which are assi...
متن کاملRole of covalent bond formation in morphology and properties of PP/PP-g-PS binary blends
PP-g-PS copolymer is a typical compatilizer used in polypropylene and polystyrene immiscible blends. PP-g-PS copolymers with different side chain lengths were synthesized, and their thermal and mechanical properties were characterized by differential scanning calorimetry (DSC), polarizing optical microscopy (POM) and dynamic mechanical analysis (DMA), respectively. The DSC and POM results show ...
متن کاملFrom molecular chemistry to supramolecular chemistry to superdupermolecular chemistry. Controlling covalent bond formation through non-covalent and magnetic interactions.
The reactions of carbon centered radical pairs often involve diffusion controlled combination and/or disproportionation reactions which are non-selective. A triplet geminate pair of radicals is produced by the photolysis of suitable ketones. The reactions of such geminate pairs can be controlled though the application of supramolecular concepts which emphasize non-covalent interaction to "steer...
