  Laser flash photolysis/transient absorbance spectroscopy was used to determine the mechanism of photo-Kolbe fluorination of carboxylic acids, RCOOH --> RF, at colloidal TiO2 suspensions in acetonitrile. Transient absorption spectra of Ph3C+, Ph3C., Ph2CH. and Ph2CH+ were observed from the photooxidation of Ph3CCOOH and Ph2CCOOH at TiO2 using 355-nm excitation. Transient decays, monitored in the presence and absence of fluoride ions, showed that the carbocations reacted rapidly with fluoride, but the neutral radicals did not. By varying the laser intensity, it was found that the photooxidation of Ph3CCOOH to Ph3C. at TiO2 occurred via a single-photon process, while the formation of Ph3C+ required two photons. This finding is in agreement with the parabolic light intensity dependence of initial reaction rates in bulk photolysis experiments. Although fluoride is atrongly adsorbed on the TiO2 surface in acetonitrile solution, the oxidizing power of photogenerated holes could be increased by coordinating HF to F-, and therefore the threshold for oxidative photochemical fluorination was extended to more positive potentials. In this way less easily oxidized carboxylic acids RCOOH could be converted to RF.

  This invention discloses novel light-emitting materials. These materials comprise a side chain which contains at least two Si or Ge atoms, such as bis(trimethylsilyl)methyl, or a side chain that includes Si—F bond, or a side chain that includes a fluorine-containing alkyl chain. This new side chain could fine tune emission color, reduce the stacking of the light-emitting materials, maintain good lifetime, and result in high PLQY.
