In this paper, $NO_2$ gas detection characteristics of Octa-dodecyloxy copper-phthalocyanine films prepared by LB method was investigated measuring the electrical conductance of these films. The electivity characteristics of these LB films exposed to $NO_2, NO, and SO_2$ gas was also investigated. Conductivity activation energy of these films as a function of temperature was obtained.

It is well known that the metallo- phthalocyanine (MPcs) are sensitive to toxic gaseous molecules such as NO$_2$and also chemically and thermally stable. Therefore, lots of MPcs have been studied for the potential chemical sensor for NO$_2$gas using quartz crystal microbalance(QCM) or electrical conductivity. In this study, thin films of octa(2-ethylhexyloxy) copper-phthalocyanine were prepared by Langmuir -Blodgett method and characterized by using UV-VIS spectroscopy and ellipsometry. Transfer condition, and characterization of LB films were investigated and preliminary results of current-voltage(I-V) characteristics of these films exposed to NO$_2$gas as a function of film thickness, temperature and temperature were discussed.

광역동요법 (photodynamic therapy, PDT)은 악성종양을 치료하기 위해 광과민제와 레이저광을 이용하는 표적지향적 항암치료법이다. 본 연구에서는 PDT에 적용할 수 있는 새로운 광과민제를 스크리닝하기 위해 4종의 phthalocyanine계 광과민제 (silver phthalocyanine, iron (III) phthalocyanine, copper (II) phthalocyanine, nickel (II) phthalocyanine)을 이용하여 폐암과 유방암 세포주에 대한 항암활성 테스트를 수행하였다. 연구결과 phthalocyanine계 광과민제들은 폐암보다 유방암에 높은 활성을 나타냈으며, 그 중 silver phthalocyanine (AgPc)는 정상세포에 대해서는 세포독성이 낮으면서도 물에 용해할 경우 청색증을 유발하지 않아 유방암에 대한 항암제로서의 개발가능성을 확인하였다.

We report the space charge and the surface potential of the interface between metal and copper(Ⅱ)-phthalocyanine(CuPc) thin films by measuring the microwave reflection coefficients S/sub 11/ of thin films using a near-field scanning microwave microscope(NSMM). CuPc thin films were prepared on Au and Al thin films using a thermal evaporation method. Two kinds of CuPc thin films were prepared by different substrate heating conditions; one was deposited on preheated substrate at 150。C and the other was annealed after deposition. The microwave reflection coefficients S/sub 11/ of CuPc thin films were changed by the dependence on grain alignment due to heat treatment conditions and depended on thickness of CuPc thin films. Electrical conductivity of interface between metal and organic CuPc was changed by the space charge of the interface. By comparing reflection coefficient S/sub 11/ we observed the electrical conductivity changes of CuPc thin films by the changes of surface potential and space charge at the interface.

We report the space charge and the surface potential of the interface between metal and CuPc according to isotropic property and different metal by measuring the microwave reflection coefficients $S_{11}$ of copper(II)-phthalocyanine(CuPc) thin films by using a near-field microwave microscope(NSMM) in order to understand. CuPc thin films were prepared on gold and aluminium substrates using a thermal evaporation method. Two kinds of CuPc thin films were prepared. One was deposited on preheated substrate at $150^{\circ}C$ and the other was annealed after deposition by using thermal evaporation methods. The microwave reflection coefficients $S_{11}$ of CuPc thin films were changed by the dependence on the heat treatment conditions. By comparing reflection coefficient $S_{11}$ we measured electrical conductivity of CuPc thin films and studied this results with respect to the surface potential and space charge of the interface between metal and CuPc thin films.

Copper-Phthalocyanine (Cu-Pc) thin films of 100nm thickness have been deposited on silicon substrates as the different heating temperatures by thermal evaporation deposition technique. X-ray patterns showed with different temperature conditions at the $2\theta$ range of 5-$55^{\circ}$. The surface roughness of Cu-Pc thin films was investigated by using an atomic force microscope (AFM). A scanning electron microscope (SEM) has been used to characterize the micro-structures and morphologies depended on the substrate temperatures.

We report the changes of the microwave reflection coefficients S$_{11}$ of copper(II)-phthalocyanine (CuPc) thin films by using a near-field microwave microscope(NSMM) in order to understand the phase transition of CuPc. For a NSMM system, a high-quality microstrip resonator coupled with a dielectric resonator was used. CuPc thin films were prepared on the pre-heated glass substrates using a thermal evaporation method. The reflection coefficients S$_{11}$ of CuPc thin films were changed by the dependence on the substrate pre-heating temperatures. By comparing reflection coefficient S$_{11}$ and crystal structures, we found the phase transition of CuPc thin films from $\alpha$-phase to $\beta$-phase at the substrate heating temperature 200 $^{\circ}C$./TEX>.

${\alpha},{\beta}$-구리 및 무금속의 프탈로시아닌을 비이온성 계면활성제를 사용하여 수용액 중에서 산화아연에 흡착시켰더니, 첨가시킨 색소가 모두 흡착되었다. 계면활성제를 사용하지 않고 술폰화된 프탈로시아닌의 나트륨염인 경우는 Langmuir 단분자 흡착성을 나타내었다. 흡착상태에 따른 증감특성을 알기 위하여 진동용량형 표면 전위계를 사용하여 광기전력을 측정하였더니, 산화아연의 고유파장과 프탈로시아닌 색소의 흡수파장에서 높은 광기전력을 나타내었다. 계면활성제를 이용하여 흡착시킨 프탈로시아닌은 산화아연에 대한 피복율(${\theta}_{BET}$)이 약 80%에서 광기전력이 크게 나타났고, 술폰화된 프탈로시아닌은 피복율(${\theta}_{BET}$)이 약 30% 부근에서 광기전력이 증가하는 경향을 나타내었다.

We studied the electrical properties of Copper(II)-phthalocyanine (Cu-Pc) as a hole transport layer in organic light emitting devices (OLEDs). OLEDs were constructed with ITO/CU-Pc/triphenyl-diamine (TPD)/tris-(8-hydroxyquinoline) aluminum ( Alq$_3$) + 4- (Dicyanomethylene)-2-methyl-6-(4-dimethylaminostyryl)-4H-pyran (DCM)/Al. It was consisted of a thin DCM in Alq$_3$emission layer. We observed that the change of recombination zone was moved toward the cathode as the hole mobility increased due to the heat-treatment temperature of Cu-Pc layer increased.
