Two photoswitchable semiconducting polymers were synthesized by covalently incorporating photochromic dithienylethene (DTE) into the main chains. Small size polymer dots (Pdots) were prepared and showed dynamic photoswitching upon alternate light irradiation. By virtue of the tunable photoswitching properties, effective pattern encoding and superresolution imaging with a resolution of up to about 30 nm were achieved.
通过将光致变色二噻吩乙烯（DTE）共价结合到主链中，合成了两种可光开关的半导体聚合物。制备了小尺寸聚合物点（Pdots），并在交替光照下表现出动态光开关特性。凭借可调的光开关特性，实现了有效的图案编码和分辨率高达约30 nm的超分辨率成像。
