摘　　要：Sensing materials possessing intrinsic color perception are indispensable prerequisites for the development of filterless photosensors,which could eliminate the need for complex device designs and avoid color distortion in post-processing.Traditional materials are constrained by complex processing methods and limited stability.Herein,a color-photosensitive array based on ionic liquid with selective photothermal conversion(ILSPC)has been developed for intrinsic color perception.Relying on the selective absorption,photothermal conversion,and thermosensitivity of ILSPC,a photo-thermo-electric sensing system has been constructed.Besides,the versatility of the two algorithms has been validated in color reconstruction and electrical signal prediction.As an exploration,the photosensitive array showcases promising color recognition capabilities,potentially propelling the evolution of flexible photosensors.
