摘　　要：Luminescent polymers have garnered considerable research attention for their excellent properties and wide range of applications in multi-responsive materials,bioimaging,and photoelectric devices.Thereout,various modulations of polymer structure are often the main approach to obtaining materials with different luminescent colors and functions.However,polymers with biodegradability,tunable color,and efficient emission simultaneously remain a challenge.Herein,we report a feasible strategy to achieve degradable and highly emissive polymers by exquisite combination and interplay of aggregation-induced emission(AIE)unit and environmental-friendly epoxide/CO_(2)copolymerization.A series of polycarbonates P-TEP_(x)CN_(y)(x=0,1,2,4,30,120;y=0,1)were prepared,with emission color changed from blue to yellow by controlling the proportion of two designed AIE-active monomers.Among them,Using P-TCN as emitting layer,high performance white light-emitting diode(WLED)device with an external quantum efficiency(EQE)of 26.09%and CIE coordinates of(0.32,0.32)was achieved.In addition,the designed polymers can be used as selective sensors for nitroaromatic compounds in their nanoaggregate states.
