| 摘 要： | A new 2D Eu-BTB framework(1) with stratified gridding structure of about 14.6×16.9was synthesized and characterized.Compound 1 displays excellent water stability with the pH 2–12. The luminescent investigations suggest that 1 could represent a chemical sensor of PO43. with high sensitivity and selectivity. Importantly, 1 as a sensor of PO_4~(3-) can be reused at least five times.On the other hand, the catalytic investigations of 1 were carried out, indicating that 1 could be demonstrated as a recyclable catalyst for CO_2 conversion with epoxides.
