There are, however, a few planar aromatic molecules with different bulk structures which do show the existence of such orientational precursors. One of these exceptions is PTCDA (3,4,9,10-perylenetetracarboxylic dianhydride) which has been extensively studied in the past and is commonly considered as a prototype system for organic thin film growth [62, 63]. Especially on Ag(l 11) an epitaxial growth of well-ordered PTCDA films was observed where molecules adopt the same arrangement as in the (102)-plane of the bulk structure of PTCDA [62]. An examination of this (102)-plane reveals that this...

To test the device model we used two different small molecule organic materials N,. V -bisgi-iiK i liylpli( iiyl i-.V. IV -diphenyl-l, 1 -biphenyl-4, 4 diamine (TPD) and 3,4,9,10-perylenetetracarboxylic bis-benzimidazole (PTCBI), whose absorption spectra and approximate energy band levels are depicted in Fig. 5.18. TPD (H.W. Sands) is a common hole transport material used in organic LEDs, making it suitable for use as the CTL. PTCBI (Sensient...

Absorption spectra, chemical structure, and proposed energy band levels of the materials used in the bi-layer hetero junction photoconductor N, N -bis(3-methylphenyl)-W,W -diphenyl-l,l/-biphenyl-4,4 -diamine (TPD, solid) and 3,4,9,10-perylenetetracarboxylic bis-benzimidazole (PTCBI, dashes). Also shown is the emission profile of the green LED (green, Apeak 532 nm) operated with a forward current of 2 A and an intensity of approximately 40 mW cnT (dotted)...

In agreement with data [3], our calculations predict a very small CT between /V,/V -diphenyl-7V,7V -bis(/-naphthyl)-l-l -biphenyl-4,4 "-diamine (a-NPD) and 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA) molecules in spite of the large difference in electronegativity. The small value of the VLS in this system is primarily explained by the weak coupling between HOMO of a-NPD and the LUMO of PTCDA.

Perylenetetracarboxylic dianhydride, PTCDA, has been used as a target material for the generation of films consisting essentially of polyperi-naphthalene (see Chart 9.10) [62, 69]. Films annealed at 350 °C immediately after deposition possessed an electrical conductivity of 10" S cm". ...

Siloxane constituted from poly(azomethine)s and a six-membered poly(imide) have been synthesized from a siloxane-containing diamine with dialdehydes and 3,4,9,10-perylenetetracarboxylic dianhydride [13]. The poly(azomethine)s emit blue light, while the poly(imide) emits green light. 

A doped material was prepared by plasma polymerisation using 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA) [67]. Electrical conductivity of the iodine-doped material decreased by five orders of magnitude and the iodine doping caused a serious structural change. 

The dimeric A(LS)2 structure was found remarkably effective even in the case where the unit A is a ionic moiety, such as viologen in 54 [78], or a strongly self-associating group, such as the NAf -disubstituted 3,4,9,10-perylenetetracarboxylic diimide core in 55 [79]. It was foimd that 54 forms a stable gel only in 1-butanol at low concentration (below 1 wt/vol %) of which the CD spectnun displayed the features typical of a chiral, clockwise aggregation of the gelator molecules. X-ray diffraction patterns of the xero-gel of 54 were similar to those of the neat crystal obtained from ethanol. They indicated the formation of a lamellar organization with an interlayer distance of 4.96 nm. The molecules 54 were proposed to exist in an extended conformation in the gel state and to be tilted relative to the normal of the...

CH2CI2 and aniline were obtained from Fischer Scientific Co. and distilled from CaH2 (Aldrich Chemical Co.). 3,4,9,10-perylenetetracarboxylic dianhydride, 2-chloro-5-nitrobenzoic acid, sodium borohydride, copper (II) acetyl-acetonate, trifiuoroacetic acid (TFA), tetrabutylammonium hexafluorophosphate (TBAPF6), dimethylacetamide (DMA), and N-phenyl-l,4-phenylenediamine were purchased from Aldrich Chemical Co. and used as received. Quinoline and triethylamine (TEA) (Aldrich Chemical Co.) were distilled in vacuo. IR spectra were obtained on a Bruker Equinox 55 Spectrometer. NMR spectra were obtained on a Bruker 250 multiprobe spectrometer. Elemental andyses were performed by Atlantic Microlabs. Mass spectrometry data were provided by the Auburn Mass Spectrometry Laboratory. 

A similar polydye, 10, was formed from the reaction of Ru(bipy)2Cl2 and N,N -bis(3-aminophenyl)-3,4,9,10-perylenetetracarboxylic diimide. This product was formed in 85% yield and had a DP of 33,000 by light-scattering photometry.
