Stretchable and flexible photoelectric materials are highly desirable for the development of artificial intelligence products. However, it remains a challenge to fabricate a stable, processable, and cost-efficient material with both high photoelectric sensitivity and remarkable deformability. Herein, a new kind of photoelectric sensitive, highly stretchable and environmentally adaptive materials was developed through in situ synthesis and π–π conjugation design. Specifically, a photoelectric elastomer zinc porphyrin SEBS(Zn-PorSEBS) was synthesized by introducing porphyrin to SEBS chain via a one-pot method. Then, graphene/zinc porphyrin SEBS (G/Zn-PorSEBS) composites were obtained by combing the elastomer with graphene sheets through solution blending. Notably, the resultant flexible composites were capable of capturing light changes with illumination on or off, and the maximum photocurrent density reached 0.13 μA cm⁻². Moreover, the photoelectric composites exhibited a dramatic elongation (more than 1000%) and an excellent tensile strength about 20 MPa. This proposed strategy represents a general approach to manufacture photoelectric and flexible materials.

光电和柔性聚（苯乙烯-b-乙烯/丁烯-b-苯乙烯）-锌卟啉-石墨烯杂化复合材料：合成、性能和机理†

可拉伸和柔性的光电材料对于人工智能产品的开发是非常可取的。然而，制造具有高光电灵敏度和显着变形能力的稳定、可加工且具有成本效益的材料仍然是一个挑战。在此，通过原位合成和π-π共轭设计，开发了一种新型的光电敏感、高伸缩性和环境适应性材料。具体而言，通过将卟啉引入SEBS链中，合成了一种光电弹性体锌卟啉SEBS（Zn-PorSEBS）。一锅法。然后，通过溶液共混将弹性体与石墨烯片材结合，得到石墨烯/锌卟啉SEBS（G/Zn-PorSEBS）复合材料。值得注意的是，所得到的柔性复合材料能够捕捉光照开或关时的光变化，最大光电流密度达到0.13 μA cm ^-2。此外，光电复合材料表现出显着的伸长率（超过 1000%）和约 20 MPa 的优异拉伸强度。该提议的策略代表了制造光电和柔性材料的一般方法。
