NPB sublimed stock
One separately contained accepted1.000g batch of N,N'-bis(naphthalen-1-yl)-N,N'-bis(phenyl)benzidine,CAS123847-85-8,C44H32N2, after vacuum-gradient purification and independent identity/quality/recovery checks. At least99.9%HPLC source grade basis; positional identity, residue and deposited cap n/k/absorption/thermal integrity independently assessed. Actual final OLED-grade caller optical/electrical/aging fit remains unproved and cannot be inferred from the chemical name.

Making outline
- Keep defined NPB synthesis feed separate, vacuum-gradient sublime into a dedicated compatible central fraction, assay recovered powder and deposition witnesses, then dry-transfer/label the accepted1.000g lot with head/tail/residue and assay stock separately retained
- Detailed procedure and acceptance remain unresearched.
What remains unresolved
- Manufacture, quantities, suitability and complete inventory remain unreviewed.
- Current memory-first method needs source and compatibility review.
Canonical reuse assessment
"Same exact molecule reused across carrier/dopant/host/blocking/cap functions where compatible; distinct prepared contamination state from crude synthetic feed. Broad existing OLED material families remain unchanged. This stock is a public candidate, not a proven privateNDP/CPL equivalent or flagship-qualified material."
