Triangular boron carbon nitrides: an unexplored family of chromophores with unique properties for photocatalysis and optoelectronics

“…Carbon-doped boron nitride nanosheets were employed in photoredox catalysis 42 and in photoelectrochemical water splitting. 43 Coordination complexes of boron atoms with carbon nitrides were synthesized and tested as emitters of OLEDs. 44,45 The absorption and luminescence spectra of a variety of planar BCN structures were investigated in the quest for improved OLED materials.…”

Vertically Aligned Graphene‐Analogous Low‐Dimensional Materials: A Review on Emerging Trends, Recent Developments, and Future Perspectives

“…[51,52] Fang et al demonstrated that the electronic properties and bandgap of vertically aligned h-BN can be altered by insertion of sp 2 carbon, as the C 2p orbitals delocalize the 2D electron system constructed by the h-BN lattice. [53] UV-Visible (UV-Vis) absorption spectra of BN-C nanosheet arrays showed two absorption characteristics signifying the development of a two-domain structure. [54] The first absorption edge corresponds to a 4.25 eV optical bandgap, which is ascribed to the h-BN bandgap but is smaller than the bandgap of pure h-BN due to the carbon-doping in BN domains.…”

“…Fang et al reported optoelectronic properties of vertically aligned BN-C nanosheet arrays with different concentrations of C in the BN matrix. [53] Fourier-transform infrared spectroscopy (FTIR) spectra with peaks at 1390-1396 cm -1 and 792-798 cm -1 are contributed due to the in-plane stretching B-N and out-of-plane B-N-B vibrations. The shifts in both B-N and B-N-B modes as compared to the other reports were proposed due to the incorporation of C in the BN matrix.…”

Non-metal sensory electrode design and protocol of DNA-nucleobases in living cells exposed to oxidative stresses

“…The oxidative stresses generate free radicals (i.e., formulation of OH• radicals), which causes DNA oxidation and damage. Therefore, DNA nucleobases, namely, Gu, Ad, Th, and cytosine and their oxidized forms are liberated [39]. NMS-2 can sensitively and selectively screen ultra-low concentrations of Gu, Ad, and Th in one step.…”

“…For instance, B dopants (i.e., p-type electron transfer) enhance electron transfer delocalization via the mechanistic formation of an ease +ve-hole vacancy on carbon electrode surfaces [37,38]. Facile changes in the distribution of electronic clouds along the entire carbon networks (distortion of sp 2 graphitization) with B-dopants are apparent [39][40][41]. Therefore, the design of electrochemical nano-sensors based on B-doped carbon materials will create electrode surface pools with abundant central active sites, curvature surface topography, and anisotropic spherule geometrics for potential sensing assays of Gu, Ad, and Th in living cells.…”
