Titanium oxide thin film could be prepared from (NH4)2TiF6 aqueous solution with addition of boric acid by Liquid Phase Deposition (LPD) process. The aspect and chemical composition of the deposited films were different according to the concentration range of (NH4)2TiF6 and H3BO3 in the treatment solution. The deposition rate of transparent TiO2 film increased with increasing concentration of added H3BO3.

Introduction of isopropyl substituents to 2 and 2′ positions of benzothiophene rings of bis(1-benzothiophen-3-yl)hexa-fluorocyclopentene increased the population of anti-parallel conformation, and enhanced the quantum yield of the cyclization reaction.

Au-dispersed T i 0 2 (anatase) thin films have been prepared by a novel method, liquid-phase deposition (LPD) The deposited film\ were characterized by XRD, XPS, TEM and UV-VIS absorption spectroscopy The results showed that the titanium oxide thin film containing Au"' ions was formed from a mixed solution of ammonium hexafluorotitanate, boric acid and tetrachloroauric acid Heat treatment above 200 "C of the deposited film under flowing air produced dispersed Au metal particles, accompanied by the crystallization of titanium oxide as a matrix The mean particle size of the dispersed Au particles was ca 15 nm The optical absorption band due to the surface plasmon resonance of the dispersed Au particles shifted toward longer wavelengths with increasing heat-treatment temperature
