新型有机光致变色材料螺噁嗪的结构确证

Confirmation of Structure for Novel Organic Photochromic Compounds Spirooxazine

采用1HNMR谱、13CNMR谱、DEPT(θ=3π/4)谱、红外吸收光谱、质谱等仪器分析手段确证了4种新合成的有机光致变色材料螺嗪化合物的结构 ,并对化合物的

Four photochromic compounds of spirooxazine were synthesized. They are 1,3,3 _ trimethylspiroindolino _ 2,3′ _ naphtho _ _ 1,4,2 _ oxazine(A); 1,3,3 _ trimethyl _ 6′ _ N _ piperidino _ spiroindolino _ 2,3′ _ naphtho _ 1,4,2 _ oxazine(B); 1,3,3 _ trimethyl _ 6′ _ dimethylamino _ spiroindolino _ 2,3′ _ benzo _ 1,4,2 _ oxazine(C); 1,3,3 _ trimethyl _ 6′ _ diethylamino _ spiroindolino _ 2,3′ _ benzo _ 1,4,2 _ oxazine(D). Their structures were identified by NMR(1H NMR,13C NMR, DEPT), IR and MS. The 1H NMR chemical shifts for the four compounds were assigned, and 13C NMR chemical shifts ofcompounds A and B also assigned. Take compound B for example, its fragmentation process of MS was discussed.
