双（1,2-二苯基环戊二烯基）二氯化锆化合物发光光谱行为及取代基效应

The electronic absorption and luminescence behavior of a number of bis(4-R-1, 2-diphenylcyclo-pentadienyl) zirconium dichloride complexes (4-R-l, 2-Ph2Cp)2ZrCl2[R=H(2), Me(3), Ph(4)] in anhydrous n-hexane were studied under an atmosphere of nitrogen. The research results showed that the electronic absorption and luminescence behavior of these compounds can be tuned by the variation of the substituents on the cyclopentadienyl groups. The absorption and emission wavelength of these complexes decreases in an order of R=Ph＞CH3＞H. As a result, complex 2 is a blue color emitter, while complex 4 is a green color emitter.
