A Trio of Small Aromatic Molecules have been Added to Our Collection!
Posted on Mon, Aug 22, 2016 by Lucy Roberts
This week's materials are a trio of small, aromatic molecules for use in OFETs, OLEDs and PV devices, including Rubrene, which holds the record for the highest recorded room-temperature hole mobility.
New products are continually being added to our collection, so make sure to keep a look out.
Rubrene
Order Code: M441

Rubrene is a molecule with a tetracene backbone and four appended phenyl rings. It is one of the most studied molecular semiconductors due to its high charge mobility. Room-temperature hole mobilities of the order of 20-40 cm2V-1s-1 have been measured for rubrene in single-crystal organic field-effect transistors (SC-OFET) . It is commonly used in organic electronics, particularly in organic light-emitting diodes (OLEDs) and organic field-effect transistors (OFETs).

CAS number | 517-51-1 |
Chemical formula | C42H28 |
Molecular weight | 532.67 g/mol |
BPhen
Order Code: M961

BPhen is commonly used as a hole-blocking or exciton-blocking layer due to its wide energy gap and also high ionisation potential. The phenanthroline unit is a small, rigid and planar with extended π-electrons and short hopping lengths that facilitate electron mobility, which is about two orders of magnitude higher than that of Alq3.

CAS number | 1662-01-7 |
Chemical formula | C24H16N2 |
Molecular weight | 332.40 g/mol |
DMQA
Order Code: M971

N,N'-Dimethylquinacridone (DMQA), is green dopant material used in OLEDs. Highly stable and longer lifetime OLED devices have been achieved by using DMQA as the dopant to a double host (aminoanthracene and Alq3). It is believed that DMQA can prevent excimer formation, thus prolonging the the lifetime of the devices.

CAS number | 19205-19-7 |
Chemical formula | C22H16N2O2 |
Molecular weight | 340.37 g/mol |
