three alternating conjugated polymers,namely PftP,PCz tP,and PSi tP,which combine a thieno[3,4-b]pyrazine(tP)unit with different benzene-based donor units such as 9,9-dioctylfluorene,9-heptadecyl-9h-carbazole and 5,5-dioctyl-5h-dibenzo[b,d]silole,were synthesized in good yield(>85%)and high molecular weight up to mn=5.82×10^(4) via direct arylation polymerization(DAr P).All the resultant polymers exhibit moderate bandgap of about 1.80 e V and strong deep red/near-infrared emitting in the solid *** them,the PSi tP-based electroluminescence(EL)devices with an arch.t.cture of ItO/PEDOt:PSS/PtAA/emitting layer/tPBi/Li f/Al give the best performance with a maximum luminance of 2543 cd/m^(2) at 478 m A/cm^(2).this work expands the application scope of high-performance conjugated polymers which can be synthesized by DAr P.

Cancer cells can evade immune recognition by losing major histocompatibility complex(mhC)class Ⅰ.hence,mhC class Ⅰ-negative cancers represent the most challenging cancers to *** drugs not only directly kill tumors but also modulate the tumor immune microenvironment however,it remains unknown wh.t.er chemotherapy-treated cancer cells can activate CD8 t cells independent of tumor-derived mhC class Ⅰ and wh.t.er such mhC class Ⅰ-independent CD8 t-cell activation can be exploited for cancer ***,we showed th.t.chemotherapy-treated cancer cells directly activated CD8 t cells in an mhC class Ⅰ-independent manner and th.t.these activated CD8 t cells exhibit virtual memory(Vm)***,in vivo chemotherapeutic treatment preferentially increased tumor-infiltrating Vm CD8 t ***,mhC class Ⅰ-independent activation of CD8 t cells requires cell-cell contact and activation of the PI3K *** CD8 t cells contribute to a superior therapeutic effect on mhC class Ⅰ-deficient *** humanized mouse models or primary human CD8 t cells,we also demonstrated th.t.chemotherapy-treated human lymphomas activated Vm CD8 t cells independent of tumor-derived mhC class Ⅰ.In conclusion,CD8 t cells can be directly activated in an mhC class Ⅰ-independent manner by chemotherapy-treated cancers,and these activated CD8 t cells may be exploited for developing new strategies to treat mhC class Ⅰ-deficient cancers.
