Aiming at molecular-based magnets, ferromagnetism of pure carbon-based materials is fundamentally and technologically extremely important for many applications. While it is still not fully understood, many recent theoretical works have suggested that one-atom-thick two-dimensional graphene materials may show ferromagnetism due to the existence of various defects or topological structures as the spin units and the possible long-range ordered coupling among them. Here, we report the experimental results on the ferromagnetism of graphene-based materials at room temperature. The observed room-temperature ferromagnetism is believed to come from the defects on graphene.

A novel hybrid material prepared from graphene and poly (3,4-ethyldioxythiophene) (PEDOT) shows excellent transparency, electrical conductivity, and good flexibility, together with high thermal stability and is easily processed in both water and organic solvents. Conductivities of the order of 0.2 S / cm and light transmittance of greater than 80% in the 400 1800 nm wavelength range were observed for fi lms with thickness of tens of nm. Practical applications in a variety of optoelectronic devices are thus expected for this transparent and fl exible conducting graphene-based hybrid material.

Have it BOth ways: Metal‐free anionic oxoboranes and Lewis acid stabilized oxoboranes that feature a formal BO double bond can be conveniently obtained from an N‐heterocyclic borinic acid in the presences of N‐heterocyclic carbenes (NHCs) and Lewis acids, respectively (see picture).
