Abstract

2D materials are gaining more and more interest owing to their promising applications in future electronic industry. Here, two new quasi-2D metal cyanurates, K4Cu3(C3N3O3)2X (X = Cl, Br), were grown and characterized for the first time. They belong to the trigonal P[3 with combining macron]m1 space group and feature an infinite Image ID:d0cc04547k-t1.gif layer, constructed by p–p conjugation in the (C3N3O3) planar six-membered-rings and d–p conjugation in the N–Cu–N linear chains. Moreover, they are indirect semiconductors with suitable bandgaps of 3.5 eV, locating between g-C3N4 and h-BN. The electronic states and anisotropic optical responses were also studied through theoretical calculations.
