Locking the phenyl rings of tetraphenylethene step by step: Understanding the mechanism of aggregation-induced emission

Stepwise locking of phenyl rings of tetraphenylethene increases the emission efficiency of luminogen solutions gradually, thus verifying the restriction of intramolecular rotation (RIR) mechanism of the aggregation induced emission phenomenon. The emissio

Bimolecular formation of radicals by hydrogen transfer, 12: Transfer hydrogenation of p-substituted α-methylstyrenes and of 9-methylenefluorene as a criterion of mechanism

The uncatalyzed transfer hydrogenation of substituted α-methylstyrenes with 9,10-dihydroanthracene (DHA), xanthene (XAN), or 9,10-dihydroacridine (DHAC) was studied mechanistically. The three hydrogen donors react at very similar rates and with similar activation parameters and with little discrimination between the various substituted styrenes. The kinetic isotope effects are also similar and the solvent effect is small. A hydrogen atom transfer mechanism (retrodisproportionation) is, therefore, preferred to a hydride transfer mechanism. This is supported by the very similar reactivity of the hydrogen transfer reaction of DHA and XAN with 9-methylenefluorene. The product yields in all reactions investigated in this project were >90%.
