Pyrene functionalized triphenylamine-based dyes: Synthesis, photophysical properties and applications in OLEDs

Pyrene functionalized triphenylamine-based dyes TP, TCP and TCCP were synthesized via alternate Heck and Wittig reactions. It was found that they could emit strong green light with high fluorescence yields because the formation of the excimer from a pyrene unit was suppressed completely. Moreover, the non-doped organic light-emitting diodes using TP, TCP and TCCP as the emitters as well as the hole-transporting materials were fabricated, and gave green electroluminescence. Notably, the device based on TP exhibited good performance with a low turn-on voltage of 2.80 V, a high maximum luminance of 29880 cd m-2 at 9.5 V, a high current efficiency of 3.34 cd A -1, and a high power efficiency of 2.67 lm w-1. It suggested that pyrene functionalized triphenylamine derivatives may have applications in non-doped OLEDs.

Polymorph-Dependent Green, Yellow, and Red Emissions of Organic Crystals for Laser Applications

Color tuning of organic solid-state luminescent materials remains difficult and time-consuming through conventional chemical synthesis. Herein, we reported highly efficient polymorph-dependent green (P1), yellow (P2), and red (P3) emissions of organic crystals made by the same molecular building blocks of 4-(2-{4-[2-(4-diphenylamino-phenyl)-vinyl]-phenyl}-vinyl)-benzonitrile (DOPVB). Single-crystal X-ray diffraction (XRD) and spectroscopic data reveal that all three polymorphs follow the herringbone packing motif in H-type aggregations. On the one hand, from P1, P2 to P3, the reduced pitch translation along π stacks increases the intermolecular interactions between adjacent molecules, therefore leading to gradually red-shifted emissions from 540, 570 to 614 nm. On the other hand, the edge-to-face arrangement and large roll translations avoid strong π–π overlap, making P1, P2 and P3 highly emissive with record-high solid-state fluorescence quantum yields of 0.60, 0.98, and 0.68, respectively. Furthermore, the optically allowed 0–1 transitions of herringbone H-aggregates of P1, P2 and P3 naturally provide a four-level scheme, enabling green and yellow amplified spontaneous emissions (ASE) with very low thresholds.
