Dodecyl β-naphthoate and 3-octadecyl pyrene were used as fluorescence probes for estimation of microscopic polarity in aggregates formed by long chain hydrocarbon C_n(n=10,12, 14,16,18)in dimethyl sulfoxide-water mixed *** polarity in the aggregates is similar to that in *** average aggregation number(N)was determined by using time resolved fluorescence technique.N is dependent on substrate chain length and varies from 15 to *** microviscosity was also measured by fluorescence depolarization *** phase transition temperature,the microviscosity in aggregates is slightly larger than that in micelle,but below this temperature,the microviscosity in aggregates is as large as that in solid phase.

The influence of different size of gold nanometer part ides (10nm, 20nm, 30-40nm) on the glucose oxidase enzyme electrode response has been investigated by using a sol-gel method which is simple and easy to study this phenomena quantitatively The response electric current was increased with the increase of the ratio of gold to GOD. The mechanism of this effect has been discussed.

Absorption and emission spectra of eight naphtholazobenzene derivatives are *** processes of n→π~* and π→π~* transition and emission processes from the excitedstates are studied separately in each compound. Intra- and inter-molecular energy transfersfrom the excited states of different chromophores are discussed. Effects of the molecularstructure and the pH value of the solution on the electronic spectra are discussed also. On thebasis of quantum chemistry theory, the spectral data are analyzed qualitatively.

The guantum yields of 1O2 generated by photosensitization of some substituted metal phthalocyanlnes(Φ▲)were measured by using DPBF(diphenylisobenzofuran)as chemical trap of 1O2 in oxygen saturated DMSO solution. Both strong electron-withdrawing(-NO2)or strong electron-donating(-NH2)group decrease the ability to produce 1O2,whereas halogenation(Cl, Br, I)changes this ability only slightly.

The ZnO-Ag core-shell ultrafine particle in ethanol was prepared by photoreduction and colloidal methods. The experimental results obtained from aboorption spectroscopy. fluorescence sopectroscopy and electron microscopy revealed that the structure of the hybrid wide ig ZnO core covered with Ag shell. The thickness of the silver layer can ho controlled by the concentration of Ag+ ions and the time of UV irradiation. The structure of the electric double layer of the ZnO seed greatly affects the formation of ZnO-Ag hybtid particle.
