GENERAL DESCRIPTION & APPLICATIONS |
||
Due to extended pi-electron cloud overlaps, organometallic molecules or aromatic
oligometers such as anthracene exhibit semiconductor properties. Conductive
polymers have extended delocalized bonds that creates electrical conductivity
when charge carriers generated make positive charges (holes) and negative
charges (electrons) move to opposite electrodes. Doping is the intentional
impurities in a pure semiconductor to generate charge carriers. The
transportation of charges is responsible for fluorescence and electrical energy.
These can form well-ordered thin crystalline films. Organic semiconductors have
some merits of self radiation, flexibility, light weight, easy fabrication, and
low cost. Organic electroluminescence materials have lead to the rapid development of
photovoltaic and display devices such as organic solar cells,
biosensitizers, OLED(Organic Light Emiting Diode),
OTFT(Organic Thin Film Transistor), Wearable Display, and e-Paper. Some examples of organic electroluminescence materials
are:
Chemoluminescence (or chemiluminescence) is the luminescence (light emission) generated as the result of direct transformation of chemical energy into light energy without showing a corresponding degree of heat. When the reactants are oxidized in the presence of catalysts, they yield intermediate complexes which get rid of the extra energy quickly in the form of light (ultraviolet, visible, or infrared) photons to become a lower energy level products. Luminol (3-Aminophthalhydrazide) is a chemoluminescent dye. It is used for biological detection of metal cations and blood. The iron in haemoglobin acts as a catalyst to accelerate the process. Luciferins are bioluminescence emitting light pigments originated by an organism like bacteria, fungi, fireflies and deep sea fish. Enzymes and proteins associated with bioluminescence have been developed for biomedical research. Coelenterazine, substrate for luciferase and photoprotein, is used as a intracellular luminophore as to measure changes in oxide and Ca2+ levels in aequorin cells. Fluorescence such as fluorescein undergoes light-emission processes, but the energy source is light absorption from an external source. Some Chemoluminescence related compounds include:
