If you work in OLEDs, OFETs, or photon upconversion, you’ve almost certainly handled rubrene at some point—probably with a mix of excitement and caution. It’s a classic organic semiconductor, fluorescent, stubbornly crystalline, and—when purified right—capable of wildly impressive charge mobility. I’ve seen teams move from “good enough” grades to high-purity material and unlock order-of-magnitude jumps in repeatability. That’s not hype; it’s process control. rubrene (Synonyms: 5,6,11,12‑Tetraphenylnaphthacene; CAS 517‑51‑1) remains a benchmark p‑type organic semiconductor. In single crystals, mobility can reach the teens (cm²/V·s), which is still jaw‑dropping. In thin films, you won’t hit those numbers, but you’ll get reliable hole transport and a bright yellow‑orange emission band—handy for OLED dopants, scintillation, and triplet–triplet annihilation upconversion (TTA‑UC). Teams often request tighter ICP‑MS thresholds for rubrene (e.g., Fe, Cu, Ni
Origin and logistics: 2‑7‑523 Jidong Building Materials, Tangshan, Hebei 064000, China. Export documentation usually includes COA, MSDS, and REACH/RoHS declarations. Handle rubrene in a dry N2 environment; minimize light/oxygen exposure. Follow standard PPE. Dispose according to local regulations; consult MSDS.Rubrene for next‑gen optoelectronics: what labs and fabs are really buying
