PDP 필터 및 광기록 매체용 색소의 합성 및 응용에 관한 연구

Abstract

In an information-oriented society,the equipmentto connecthuman with thevariousinformation appliancescontaining an enormousamountofdatais the display. LCD,PDP,FED,OLED,etc are available on the market. Amongthem,PDP isthemostattactiveforlargescalescreen. PDP (PlasmaDisplayPanel)isthedisplayshowingthepictureandgraphic with R,G and B colorsexcited from thephosphorpastesby theplasmaof ionized gas. Itis large-screen and small-thickness display,compared with CRT. It also has a high contrast ratio,brightness,superior luminous efficiencyandwideviewing angle,soithasbeeninthelimelight. However,itemits electromagnetic waves,nearinfrared rays (NIR),and orange light(580~600nm)radiatedfrom thebuffergassuchasHe,Xe,somakersattach the filteron PDP panel. NIR radiated from the PDP affects the electronic equipmentlocated around thePDP,such asa cordlesstelevision ora video deck making use of a near infrared light remote controller,and causes malfunctions. Therefore,PDP filterincludesthefunctionaldyeshieldingNIR. Microwaveenergy hasbeen known astheclean energy with thedifferent heating mechanism. So,many researchers have investigated to apply the eactionsystem withmicrowaveenergytothechemicalreactions. In thisstudy,Isynthesized dithiolenemetalcomplex derivatives,which is used as PDP filter for NIR cut, by molecular design and microwave synthesis. The polymer films containing dithiolene compounds were also made for NIR cut film of PDP and measured optical properties. The structures ofsamples were confirmed by 1H-NMR and FT-IR,and their opticalpropertiesweremeasuredby meansofUV-VIS-IR spectroscopy. On the other hand, property of dithiolene compound as photostabilizer on squarylium dye showing the photofading was measured by comparing the changeofabsorbance.
