Direct observation of mass transfer at solid-liquid interface by laser flash photolysis of the interface probe molecules

Article Abstract:

An interfacial probe molecule is reported, which could generate active intermediate species capable of undergoing interfacial chemical reactions and it indicates the start of an interfacial process when subjected to UV laser flash photolysis. A reaction scheme involving surface-assisted ionization of the charge separation pair is proposed to account for the coupling between the interfacial chemical reaction and the photoacoustic effect.

Supramolecular structures and assembly and luminescent properties of quinacridone derivatives

Article Abstract:

The synthesis and single-crystal X-ray structures of two quinacridone derivatives, N,N'-di(n-butyl)quinacridone and N,N'-di(n-butyl)-1,3,8,10-tetramethylquinacridone are reported, and the (super 1)H NMR, absorption, photoluminescent, and electroluminescent characteristics are presented. It is demonstrated that the two quinacridone derivatives are characterized by intermolecular pi...pi stacking and hydrogen bonding interactions.

Surface-binding forms of carboxylic groups on nanoparticulate TiO (sub 2) surface studied the interface-sensitive transient-state molecular probe

Article Abstract:

A new method to study the surface binding between the carboxylic group and the TiO (sub 2) surface atoms by using an interface-sensitive molecular probe is proposed. The principle underlining this method is based on the triplet-triplet absorption of the probe molecule all-trans-retinoic acids (ATRA) formed by the photoinduced charge recombination between the TiO (sub 2) nanoparticle and the probe molecule.
