Abstract Oxygen is ubiquitous and vital to life, industry, and environmental safety, so accurate and reliable oxygen sensing and detection are of great significance, especially for oxygen in the low concentration range. Herein, two pure organic metal‐free room‐temperature phosphorescence (RTP) materials were developed using a covalent trimerization strategy of thianthrene (TA), which exhibit high oxygen sensitivity and fluorescence‐RTP separated dual emission due to the moderate spin‐orbit coupling (SOC).
