▎ 摘　　要

For the progressive development of spintronics as the next generation information technology source, it is essential to look for materials with high abundance, long spin lifetime, easy manipulation of spin current, and temperature/strain resistivity of spin properties. In this respect, the main group based two-dimensional (2D) semiconductors are systems of immense research interest in the field of spintronic devices for their novel characteristics and notable application in spintronics nanotechnology. The discovery of graphene set off the journey of 2D materials, and many of them have been identified as potential candidates for spintronics applications owing to their extraordinary properties and atomically thin structures. Since the last few decades, several theoretical and experimental reports agreed with the novel chemistry between 2D materials and nanoscale spintronic devices. This review highlights the most progressive and important theoretical and experimental studies of main group based 2D spintronics reported until present which have contributed to inspiring new spintronic devices and have given direction for further development. We have systematically discussed the main group based 2D spintronic materials in the two categories of metal incorporated and metal-free systems. Besides, vital focus is given to the useful theoretical techniques for spintronics studies and suitable designing of spintronic materials and devices. We have also briefly discussed the past, present, and future perspective of spintronic devices.
