A drop-casted near-infrared (NIR) organic phototransistor (OPT) based on ultrathin nanocrystals of octamethyl substituted zinc(II) phthalocyanine (ZnMe2Pc) has been developed, as an attempt to realize NIR detecting property of metal phthalocyanine (MPc) in OPT, and a preliminary feasibility exploration of solution processing for MPc-based OPT fabrication. The broad and strong NIR light absorption together with the enhanced hole mobility of these ZnMe2Pc nanocrystals led to the significantly increased performances in NIR detecting and sensing compared with that of the vacuum deposited OPT. The cost-effective processes both in materials preparation and device fabrication are promising in future application.

基于八甲基取代锌酞菁超薄纳米晶体的固溶近红外光电晶体管

为了实现金属酞菁(MPc )的近红外检测性能,已经开发了一种基于八甲基取代锌酞菁(ZnMe 2 Pc)超薄纳米晶体的近红外(NIR)有机光电晶体管(OPT )。在OPT中进行,并对基于MPc的OPT制造中的溶液处理进行了初步的可行性探索。这些ZnMe 2 Pc纳米晶体具有广泛而强大的NIR光吸收以及增强的空穴迁移率,与真空沉积的OPT相比,在NIR检测和传感方面的性能大大提高。材料制备和器件制造中具有成本效益的工艺在未来的应用中很有前途。
