We have developed an efficient method of the synthesis of 2,3‐dihydroquinazolin‐4(1H)‐one (DHQ) using yttrium nitrate catalyst at room temperature. The synthetic method is simple, convenient, and easy product isolation. Best results obtained in CH3CN, DMF, or water. The synthesized DHQ derivatives are found to be good fluorophores, and their characteristic photoluminescence properties are measured...
