High-Performance, Fullerene-Free Organic Photodiodes Based on a Solution-Processable Indigo

The solution-processed fullerene-free organic photodiodes show an almost spectrally flat response with a high responsivity (0.4 A W(-1) ) and a high detectivity (1 × 10(12) Jones). These values are comparable to silicon-based photodiodes.

However, these devices involve the deposition of multiple layers (up to 32 layers) and require the use of the expensive molecular beam technique. Recently, solution-processed small molecular or non-polymeric OPDs have also been demonstrated. However, the performance thus far has fallen behind their polymeric and/or evaporated small-molecular counterparts, especially in terms of detectivity, broad spectral response, and responsivity.

High-Triplet-Energy Dendrons: Enhancing the Luminescence of Deep Blue Phosphorescent Iridium(III) Complexes

This report shows that when a fac-tris[1-methyl-5-(4-fluorophenyl)-3-n-propyl-1H-[1,2,4]triazolyl]iridium(III) complex core is encapsulated by rigid high-triplet-energy dendrons, both the physical and photophysical properties can be optimized. The high-triplet-energy and rigid dendrons were composed of twisted biphenyl dendrons with the twisting arising from the use of tetrasubstituted branching phenyl rings. The blue phosphorescent dendrimer was synthesized using a convergent approach and was found to be solution-processable and to possess a high glass transition temperature of 148 degrees C. The dendrimer had an exceptionally high solution photoluminescence quantum yield (PLQY) of 94%, which was more than three times that of the simple parent core complex (27%). The rigid and high-triplet-energy dendrons were also found to control the intermolecular interactions that lead to the quenching of the luminescence in the solid state, and the film PLQY was found to be 60% with the emission having Commission Internationale de l&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;Eclairage coordinates of (0.16, 0.16). The results demonstrate that dendronization of simple chromophores can enhance their properties. Single layer neat dendrimer organic light-emitting diodes (OLEDs) had an external quantum efficiency (EQE) of 0.4% at 100 cd/m(2). Bilayer devices with an electron transport layer gave improved EQEs of up to 3.9%. Time-resolved luminescence measurements suggest that quenching of triplets by the electron transport layer used in the bilayer OLEDs limits performance.

Thus, the micropore volume of eth-SWNH-50 is twice that of pristine material. For the oxidized SWNHs (O 2 -ox-SWNH and H 2 O 2 -ox-SWNH) the surface area increases slightly after compression. The dependence of the mesopore volume on the liquid used for the SWNHs dispersion is complex. There is a significant decrease in the mesopore volume for the compressed gl-SWNH. However, the compression of eth-SWNHs does not change the mesopore volume, although it alters the mesopore size distribution as shown above.
