The increased requirements for highly performing devices raised during the last years concerns regarding the supply of raw materials, especially regarding rare metals and semiconductors. For this reason, our research focused in the development of new, highly efficient materials based on carbon. The development of new synthetic techniques and the strong advances in characterization methods enabled a new era in materials science, around carbon. From the beginning of the XXI century, the development of graphene, nanotubes and fullerenes have boosted this research, with particular focus on 2D covalent graphitic-like structures. Later on, the introduction of heteroatoms in these graphitic frameworks have paved the way for the development of high performing materials in a wide range of applications and devices. Among those, the introduction of nitrogen in certain fashions was proven to boost conductivity and oxidation stability, even increasing the Fermi level above the level of noble metals, nowadays commonly referred to as "Noble Carbons". Old materials as carbon nitride made a strong comeback, and new materials classes with extraordinary properties were explored, such as ternary boron carbon nitrides, C2N and more. Recent research focused especially on the introduction of nitrogen into covalent sp -hybridized structures, with less attention paid to materials composed of carbon and oxygen. The broadly known carbon oxides are carbon monoxide (CO) and carbon dioxide (CO2) are gases. However, there are countless more carbon oxide compounds, among the linear carbon dioxides, with the general formula CnO2 (n≥1). Among those, carbon suboxide (C3O2) was already an industrial product used at the ton scale in the early 20 th century and attracted attention as a highly reactive synthon for the synthesis of heterocycles and malonyl derivatives. C3O2 behaves alike a bisketene, and was described by Kappe and Ziegler as a double dehydrated malonic acid. First reports on higher carbon oxides date back to Brodie in 1873, when he exposed carbon monoxide to an electric current and reported on the formation of CO2 and a redbrown film deposition on the reactor walls. Further analysis these films led to the conclusion that the compounds were oxides of carbon possibly belonging to a series, analogous to the series of hydrocarbons, which he named "oxycarbons". This report has inspired further research by Diels and Wolf, who in 1906 were able to isolate and characterize carbon suboxide (C3O2) obtained from the dehydration of diethyl malonate by large excess of P2O5 at 300°C. In last century, further methods for the synthesis of carbon suboxide have been implemented, and summarized in the following (Fig. ). Figure 1. Summary of synthetic methods for carbon suboxide synthesis.
