摘　　要：Recognized as one of the important active species involved in varicus ractions,singlet oxygen(^(1)O_(2))shows potential applications in chemical.blological,and environmental related fields.However,the con-trolled capture and release of^(1)O_(2)are still facing huge challenges due to its short lifetime and high re-activity.Herein,a framework-interpenetration tuning strategy was applied on a metal-organic framework(MOF)that aiming to improve the capture and release rate of O.The porosity of the MOF was remark-ably enhanced with the structural evolution from seven-fold(termed NKM-181)to six-fold interpene-tration(termed NKM-182),and the active anthracene sites became much mare accessible.Such drastic process can be achieved as simple as exchanging the primitive MOF in selected solvent and occurred surprisingly as single-crystal to single-crystal transformation.Also,additionally owing to the unblocked regular channels,NKM-182 shown significantly improved^(1)O_(2)trapping and releasing rates compared to strates an unprecedented regulation of^(1)O_(2)capture and release that of in NKM-181.This work demon process,along with achieving the highest^(1)O_(2)capture and release rate among reported porous materi-als.furthermore.the obtalned endoperoxides with^(1)O_(2)loaded(termed EPO-NKM-181 and EPO-NKM-182)can be used as a high efficiency smart material for anti-fake application.
