与大多数报道的基于UV/维斯吸收系统的器件相比，基于双折射开关的逻辑器件非常灵敏。在此，我们证明了一个简单的分子，5，10，15，20-四-（4-氨基苯基）卟啉（TAPP），通过分子内电荷转移和/或聚集引起的淬灭显示质子化诱导的多个发射开关。通过将分子间组装与双质子化TAPP（TAPPH 2（2+））的分子内光开关结合，可以实现高灵敏度的INHIBIT和XOR逻辑门。此外，分子模拟已经进行了DFT的发射开关过程的更好的理解。
Fluorescence-switch-based logic devices are very sensitive compared with most of the reported devices based on UV/Vis absorption systems. Herein, we demonstrate that a simple molecule, 5,10,15,20-tetra-(4-aminophenyl)porphyrin (TAPP), shows protonation-induced multiple emission switches through intramolecular charge transfer and/or aggregation-caused quenching. Highly sensitive INHIBIT and XOR logic gates can be achieved by combining the intermolecular assembly with the intramolecular photoswitching of diprotonated TAPP (TAPPH2(2+)). In addition, molecular simulations have been performed by DFT for a better understanding of the emission-switching processes.
