OLED
Semikonduktor padat berukuran 100-500 nm
OLED dapat terdiri dari 2-3 lapisan senyawa
organik.
bagian OLED : substrat, anoda, lapisan senyawa
organik, serta katoda.
OLED 2 lapis : Conducting layer dan Emissive layer.
OLED 3 lapis : Electron Transport Layer, Emissive
Layer, Hole Transport Layer.

Mengemisikan cahaya
Kaya warna (termasuk hitam)
View angle lebih luas
Konsumsi energi lebih rendah
Biaya produksi OLED lebih rendah
dibandingkan produksi LCD
Susbstrat fleksibel

Metal chelates
Flourene, Carbazole, Maleimide
Anthracene
0,5000 g 1,2-diaminobenzene dilarutkan
dalam 20 mL metanol (suhu kamar)
diaduk sampai larut dan
ditambah 1 gram benzil
Larutan diaduk, dipanaskan dalam
microwave selama 20 detik
ditambah 1-2 tetes H2SO4 pekat
(pH ± 4-5)
Larutan disaring dan dicuci sedikit metanol,
tampung filtratnya
Filtrat dievaporasi hingga terbentuk kristal
coklat muda
Kristal dikeringkan
Kristal diuji kemurniannya (TLC), titik leleh,
spektrum florosensi IR, MS dan NMR
