Preparation, single-crystal structure and room-temperature phosphorescence of a covalent organic polymer containing Te-O-P bonds.

ABSTRACT: Room-temperature phosphorescent (RTP) single crystals of covalent organic polymers (COPs) are rarely reported due to the huge challenge in preparing single crystals from solutions as well as the difficulty in realizing RTP in metal-free organic molecules. Compared to other main group elements, tellurium is rarely successfully introduced into functional single-crystal COPs. Herein, we prepared colorless single crystals of a COP (CityU-21) through a reaction between tellurinyldibenzene and [1,1'-biphenyl]-4,4'-diyl-bis(phosphonic acid). Single crystal X-ray diffraction (SCXRD) analysis indicates that CityU-21 is a one-dimensional organic polymer through the covalent connection (Te-O-P bonds) between Te(Ph)₂ moieties and [HO₃P-Ph-Ph-PO₃H] units. Due to the exi
