분자 모델링에 있어서의 Conformational Analysis

신동명 弘益大學校 科學技術硏究所 1993 科學技術硏究論文集 Vol.3 No.-

The conformational analysis of ethane, biphenyl, phenylazonaphthalene, and 4-(4-Nitrophenylazo)-1-naphthol was conducted. The difference from the literature values was ascribed to the limited calculations of personal computer. As the angle of the naphthyl group varied from the s-cic planar structure, the conformation energy decreased, and generated a local minimum at 60.7˚for phenylazonaphthalene, and 52.1˚for 4-(4-Nitrophenylazo)-1-naphthol.

불포화폴리에스터(USPE)수지의 경화동역학에 관한 연구

申東明,林成澤 弘益大學校 科學技術硏究所 1997 科學技術硏究論文集 Vol.8 No.-

In this work we investigated the curing process of unsaturated polyester resing in styrene system. An thermosetting resin experiences a complicated mechanism in curing reaction with many annexes. We used the Lee's and Ryan & Dutta's model to predict such mechanism. The octadodecanoxy derivative of thephthalocyanine which has such long hydrocarbon chains around the skeleton of the phtalocyanine was synthesized. First of all, ortho-catechol was treated with 2 moles of 1-bromododecane to yield ortho-didodecanoxybenzene(I). Second, bromination of I resulted in dibromo-didodecanoxy-benzene(Ⅱ) where the para positions to the dodecanoxy groups were brominated. Finally, reaction of Ⅱ with an excess of CuCN under an N₂atmosphere gave the intermediate dicyano-didodecanoxy-benzede(Ⅲ), in situ, and futher heating in dry DMF with more CuCN gave the final product, octadodecanoxy derivative of the phthalocyanine. The synthetic method developed herein provides a general way to synthesize the variety of the phthalocyanines which displays many different substituents such as long hydrocarbons around its skeleton and contains a various metal inside of the phthalocyanine.

Interfacial properties of electrode and organic thin layer is one of the most important factor in performing a light emitting diodes(LED). Phthalocyanine copper was used as a buffer layer to improve interface characteristic, so that device efficiency was improved. In this study, LEDs were fabricated as like structures of ITO / N,N' - diphenyl - N,N' - di(m-tolyl) - benzidine(TPD) / 8-Hydroxyquinoline aluminum(Alq) / Al and ITO / N,N'- diphenyl - N,N' - di(m-tolyl) - benzidine(TPD) / 2- (4-biphenylyl) - 5(4-tert-butyl-phenyl) -1,3,4 -oxadiazole(PBD) / Al. In these devices, CuPC was layered at electrode/organic layer interface. As position is changing and thickness is changing, devices showed different phenomena respectively. We showed in this study that luminescence efficiency was improved with CuPC layer in LEDs. Characteristic of CuPC will be discussed with I-V curve, EL.

申東明,林成澤 弘益大學校 科學技術硏究所 1998 科學技術硏究論文集 Vol.9 No.2

In this work, optical properties of organic electroluminescent(EL) cell fabricated with dye-doped polymer. Poly(9-vinylcarbazole) was doped with fluorescent material, rubrene, and fabricated to thin film on quartz plate via spin-casting technique. In case of undoped PVK thin film, an blue-shift of emission peak was observed, which may be obtained through annealing process. On the other hand, rubrene-doped PVK thin film did not show significant emission shift and linear increase with doping ratio. This results provide an maximum improvement of emission efficiency obtainable via annealing process. Relative increasement of emission intensity with doping ratio was decreased by the annealing process. From these results, we could conclude that we can improve the emission efficiency of dye-doped polymer thin film via annealing process. In fabricating the EL device, one can utilize this results and obtain improved EL devices.

유기전기발광소자 제작을 위한 고효율 적색 유기 발광체 개발 및 공정 확립을 위한 연구

In this study, we synthesized a red-light emitting material, which is based on malononitrile moiety, and applied it as a red light emitter in OLED. The OLEDs structure can be described as indium tin oxide(ITO)/hole transporting layer/emitting layer/electron transporting layer/LiF/Al. The hole transporting layer was composed of N,N-diphenyl-N,N-di(3-methylphenyl)-1,1-biphenyl-4,4-diamine(TPD). The electron transporting layer consists of tris(8-hydroxyquinolinato) aluminum(Alg3). A1g3 exhibits high performance as an electron transport material and an emitting material. Emitting layer was composed of 2,6-dimethyl-4H-pyran-4-ylidene)malononitrile(d-DCM). The UV/visible absorption spectra and photoluminrscent(PL) spectra of the d-DCM showed luminescence maximum at 484nm and maximum at 611nm. Red color emission peak was confirmed at 650nm. One of the weak points to these systems is the difficulty to fabricate dye-doped monomeric organic layer. To realize the organic multi-color electroluminescence display with fine pixels, it is required to fabricate the light-emitting layer with single molecule in OLEDs. In this system, the characteristics of current density-applied voltage were typical one of that of diodes.

4-(4-Nitro phenylazo)-1-naphthol의 광화학

申東明 弘益大學校 科學技術硏究所 1992 科學技術硏究論文集 Vol.2 No.-

The acid and base properties of organic dyes are of current interest. The 4-(4-nitrophenylazo)-1-naphthol(NPNOH) was purified, and characterized spectroscopically. The azo-compound has electron donor and acceptor, which generate large solvatochromic behavior. The electronic transition energies of the acid(-OH) and base(-O-) forms were 458nm(76.4 kcal/mol) and 634nm(55.2 kcal/mol). The pKa value calculated was 15.5 which was fairly large for most organic dyes. The distribution of the dye in micellar solutions(SDS, CTAB, ...) will be discussed. The head-group charge in surfactant molecules are important for the electronic transition energy and orientation of the dye molecules in micellar solutions. The electronic transition energies will be compared with those of Oalkylated NPNOH, (NPNOR).

Solvato chromic effects and hydrogen bonding interaction of HN and ?? were investigated. UV-visible absorption spectra and fluorescence spectra of HN were obtained in organic solvents with various polarity. The electronic transition energies of HN and ?? were plotted agained empirical solvent polarity parameters. Taft ??, Reichard's ?????, Dong and Winniko's Py, and Kodower Z. Correlation with Taft ??parameter were reasonablly good, and much better correlation was observed when it was plotted against with energy calculated from ??????????????????????????. ????? and Z were not suitable to correlate the solvation properties of HN. Py showed reasonable correlation with electronic transition energy of HN. ?? showed little fluorescence and the absorption energy were shifted to red.
