Incorporation of the dimeric phthalocyanine into sandwich phthalocyaninato europium framework extends the conjugated electronic molecular structure and optimizes the ambipolar semiconducting properties of the QLS thin film-based OFET device, resulting in a significant increase in the hole and electron mobilities from 4.30 × 10⁻⁷ and 0.70 × 10⁻⁷ cm² V⁻¹ s⁻¹ for monomeric phthalocyanine-containing triple-decker Eu₂[Pc(SC₆H₁₃)₈]₃ (1) to 0.07 and 0.06 cm² V⁻¹ s⁻¹ for the dimeric phthalocyanine-containing quintuple-decker [Pc(SC₆H₁₃)₈]₂Eu₂[BiPc(SC₆H₁₃)₁₂]Eu₂[Pc(SC₆H₁₃)₈]₂ (2). This in turn induces an enhanced gas sensing detection performance for NO₂ with the sensitivity increasing from 23.4% for 1 to 46.7% ppm⁻¹ for 2. The present result appears interesting in terms of improving the gas-sensing properties of phthalocyanine-based molecular materials via molecular design and synthesis rather than tuning the film morphology.

将二聚酞菁掺入三明治酞菁cyan-to骨架中可扩展共轭电子分子结构并优化基于QLS薄膜的OFET器件的双极性半导体性能，从而使空穴和电子迁移率显着提高，从4.30×10 ^-7和对于含单体酞菁的三层式Eu ₂ [Pc（SC ₆ H ₁₃）₈ ] ₃（1）为0.70×10 ^-7  cm ²  V ^-1  s ^-1至0.07和0.06 cm ²  V ^-1  s ^-1用于二聚体含酞菁的五聚体[Pc（SC ₆ H ₁₃）₈ ] ₂ Eu ₂ [BiPc（SC ₆ H ₁₃）₁₂ ] Eu ₂ [Pc（SC ₆ H ₁₃）₈ ] ₂（2）。这又感应出增强的气体感测检测性能NO ₂与灵敏度从23.4％增加为1 至46.7％PPM ^-1为2。在通过分子设计和合成而不是调节膜形态来改善基于酞菁的分子材料的气敏特性方面，本发明的结果似乎是令人感兴趣的。
