Developments in the field of LEDs are occurring all the time. There are new white organic LEDs, new green polymer LEDs and new blue polymer LEDs. Ashwell et al. are developing molecular diodes from a bilayer of electron-rich and electron-poor molecules. ... 

Acceptor/Sensitizer/Donor Multilayer Systems A variety of electronic components with molecular dimensions have been investigated since the introduction of the foresighted concept of molecular diode by Aviram and Ratner [30]. For example, Mezger and Panetta [31] have made an effort to realize the molecular diode proposed by them. 

Modification of head group (R) allows control of monolaya- surface properties and monolayer thickness, (b) gold break junction spanning molecule acting as a molecular diode. 

Molecular Diodes Starting from the AR rectifier [3] to till date, the common construction principle of organic molecular rectifier adopted is as shown in Fig. 4. A comparison of the AR rectifier (Fig.l) with that of the semiconductor diode will give a clear idea about the rectification ability of general organic molecular rectifiers.
