A novel asymmetrically substituted amphiphilic phthalocyanine, 1,4-di(2-hydroxyethoxyl)-8,9,16,17,23,24-hexapentyloxylphthalocyaninozinc ( asy - PcZn ), was synthesized. It can be deposited as well-ordered LB films. Significant structural changes of the films were observed by UV-vis absorption spectra and low-angle X-ray diffraction after the films were annealed at 150 °C. What is more interesting is that the initial conductance of the films in air decreases and the response signal to NH 3 is weaker with longer response time after annealing compared with that of the unpretreated films.

AbstractThe dual laser-produced plasma technique for the study of ionic absorption spectra has been developed by the use of two Q-switched ruby lasers to enable independent generation of the absorbing and back-lighting plasmas. Optical pulse handling is used in the coupling cicuits to enable reproducible pulse delays from 250 nsec. to 10 msec, to be achieved. At delay times > 700 nsec. spectra of essentially pure neutral species are observed. The technique is valuable, not only for obtaining the neutral spectra of highly refractory and/or corrosive materials but also for studying behaviour of ionic species as a function of time. Typical spectra are shown in Fig. 1.

Carbon Ions

AbstractThe photoabsorption spectra of the carbon ions have been obtained by using two laser-produced plasmas. The photoionization cross-section of the CV has been absolutely measured and the value at threshold, σ=(4.7±0.5) × 10−19cm2, as well as its behaviour at higher energies agrees quite well with the theoretical calculations.
