Abstract
Extending molecular conjugation accurately modulates UORTP in a series of phosphorescence units. (Br)PyCz shows red or NIR ultralong phosphorescence as extended conjugation reduces the T 1 energy level and results in a phosphorescence redshift. A rigid PVA matrix and heavy Br atoms enhance UORTP.
