摘要
The synthesis of an new photochromical compound,1,3,3 trimethyl 6′ (1 piperidinyl) spiro[2h indole 2,3′ [3H]pyridobenzoxazine (SP3),and an improved way for the synthesis of 6 hydroxyquinoline were descrided.The absorption spectrum of the colored metastable form SP3 shows prominent absorption peak at 560nm at 60℃?
