采用受体掺杂策略对共轭微孔聚合物的物理化学性质进行了调节。这允许通过引入低负载量（0.1-5摩尔%）的受体共聚单体，例如苯并噻二唑（BT）、双噻吩苯并噻二唑（TBT）和二萘嵌苯二酰亚胺（PDI）来控制天然聚亚苯基网络的荧光。荧光量子产率比类似的无孔聚合物高约10倍，因为避免了在多孔网络中的链聚集。使用该方法制备了具有高量子产率的白色发射CMP。通过改变单体的加入顺序可以制备不同的畴结构，这对荧光性质有很大的影响。这些掺杂的多孔聚合物也可以用作挥发性有机化合物（VOC）的荧光传感器。
The photophysical properties of conjugated microporous polymers (CMPs) are tuned using an acceptor doping strategy. This allows the fluorescence of a native polyphenylene network to be controlled by introducing low loadings (0.1-5 mol %) of an acceptor comonomer, such as benzothiadiazole (BT), bisthiophenebenzothiadiazole (TBT) and perylenediimide (PDI). Fluorescence quantum yields are around 10 times higher than analogous nonporous polymers because of avoidance of chain aggregation in the porous network. White emitting CMPs with high quantum yields are prepared using this approach. Different domain structures can be prepared by changing the addition sequence of the monomers, and this has a strong effect on the fluorescent properties. These doped porous polymers can also be used as fluorescence sensors for volatile organic compounds (VOCs).
