The copolymer film containing about 1 wt% diphenyliodonium tetrafluoroborate functions as a negative-working deep UV resist: it has a relatively high sensitivity of 70 mJ/cm2 and a high contrast of 4.36 upon exposure to 248 nm light from a KrF excimer laser.
Photochemical Reactivity of 3-Ethoxycarbonylfurocounarin
Authors: Ratiner Boris D , Otsuki Tetsuo 
Published: May 2006

Abstract
Photochemical reactivity of 3-ethoxycarbonylfurocoumarin is studied. Upon irradiation, 3-ethoxycarbonylfurocoumarin forms a cyclobutane with a variety of alkenes at the 3,4-double bond in solution, whereas a similar cyclobutane is formed at the 4′,5′-double bond in DNA. The different site-selectivity in solution from DNA is explained by assuming the involvement of the triplet excited state.

Published: May 2006

Abstract
In the photosubstitution of [Ru(bpy)3]2+ in aqueous acidic (HX) solutions, the quantum yield of the initial breaking of a Ru–N(bpy) bond changed 7 fold depending on the kind of X− in the order, CF3SO3− &lt; NO3− &lt; HSO4− &lt; Cl− &lt; Br−. In HCl–NaCl system it increased linearly with increasing [Cl−]. The photosubstitution must have proceeded with a mechanism of associative nature.

Authors: Kunugi Yoshihito , Fuchigami Toshio , Nonaka Tsutomu 
Published: May 2006

Abstract
A nickel electrode composite-plated with nickel and poly(tetrafluoroethylene) was used in the cathodic reduction of carbonyl compounds to give high current efficiencies for the corresponding alcohols in aqueous sulfuric acid. This fact may indicate that this hydrophobic electrode has apparently a high hydrogen-overvoltage and consequently suppresses effectively hydrogen evolution.
