TL;DR: In this article, the interaction mechanisms at metal-organic and organic-organic interfaces in highly-ordered ultra-thin layers of the dye molecules 3,4,9,10-perylene-tetracarboxylic-dianhydride (PTCDA) and tin(II)-phthalocyanine (SnPc) on single crystalline noble metals were investigated by means of in situ differential reflectance spectroscopy (DRS), followed by an extraction of the optical functions by application of a numerical algorithm.

TL;DR: In this article, a 3,4:9,10-Perylenetetetracarboxylic dianhydride (PTCDA) powder obtained from Sigma-Aldrich was purified by three cycles of temperature gradient sublimation in an evacuated quartz glass tube providing variable conditions.

TL;DR: In this article, the dissociation processes of excited states in vapor-deposited thin films of N,N′-dimethylperylene-3,4,9,10-dicarboximide (Me-PTCDI) and 3, 4, 9, 10-perylenetetetracarboxylic dianhydride (PTCDA) are investigated in detail by means of electric field induced fluorescence quenching and photoresponse.

TL;DR: Experimental evidence is presented for a phase transition from a two-dimensional gas to a highly ordered molecular solid via an intermediate metastable phase with moderate order which undergoes a reversible orientational shift upon temperature variation.

TL;DR: In this article, the optical absorbance behavior of ultrathin 3,4,9,10-perylenetetetracarboxylic dianhydride (PTCDA) films epitaxially grown on Au(1,1/1) and Au(0,0/0) was investigated.
