Reinvestigation of solvent catalyzed ground-state reverse proton transfer in 7-hydroxyquinoline
Chou, Pi-Tai,Martinez, Shannon Studer
, p. 463 - 470 (1995)
The dynamics of the ground-state proton transfer of 7-hydroxyquinoline have been reinvestigated in various alcohol solvents by pulse pump-cw probe transient absorption in combination with two-step laser-induced fluorescence measurements.The results show a nearly temperature-independent kunetic isotope effect for the reverse proton transfer in the ground state, consistent with the previous study.The overall proton transfer dynamics can be rationalized based on a kinetic derivation incorporating solvebt reorganization forming a specific cyclic solvent/solute complex, and then the dissociation and actual proton transfer of this hydrogen bonded complex.

Interest and challenges remain in designing and synthesizing catalysts with nature-like complexity at few-nm scale to harness unprecedented functionalities by using sustainable solar light. We introduce “nanocatalosomes”—a bio-inspired bilayer-vesicular design of nanoreactor with metallic bilayer shell-in-shell structure, having numerous controllable confined cavities within few-nm interlayer space, customizable with different noble metals. The intershell-confined plasmonically coupled hot-nanospaces within the few-nm cavities play a pivotal role in harnessing catalytic effects for various organic transformations, as demonstrated by “acceptorless dehydrogenation”, “Suzuki–Miyaura cross-coupling” and “alkynyl annulation” affording clean conversions and turnover frequencies (TOFs) at least one order of magnitude higher than state-of-the-art Au-nanorod-based plasmonic catalysts. This work paves the way towards next-generation nanoreactors for chemical transformations with solar energy.
