Code and derived data for: The Meta-Link Rule Revisited: Relaxed Triplets and Non-Radiative Loss Decide Deep-Blue Phosphine-Oxide Hosts

Literature population (Supporting Data 1), analysis plans (Supporting Data 2-5), DFT result tables with provenance, figure source data and code. Methods: Scripts are written in Python 3 (NumPy, SciPy, pandas, matplotlib; RDKit for structure drawings where used). Each script reads the tables of this record or the raw files of the experiment records and writes numerical tables and figure panels (vector PDF with a 600-dpi PNG). Literature population of emitters re-extracted from the primary sources; pre-registered population tests (plans in prereg/); host radiative and non-radiative rates with Monte Carlo uncertainties; parsing of the PBE0 outputs and DFT descriptors; figure and table scripts. Companion paper: The Meta-Link Rule Revisited: Relaxed Triplets and Non-Radiative Loss Decide Deep-Blue Phosphine-Oxide Hosts (manuscript prepared for Advanced Functional Materials). Raw instrument files are in the experiment records of the series (AFM, UV-Vis, DRS, ellipsometry, PL, time-resolved PL, CV, DSC/TGA, XRD, FTIR, NMR/MS, electron microscopy, J-V, impedance, DFT).
