Phenyl-Modified Carbon Nitride Quantum Dots with Distinct Photoluminescence Behavior

open access: yesAngewandte Chemie - International Edition, 2016
A novel type of quantum dot (Ph-CN) is manufactured from graphitic carbon nitride by “lining” the carbon nitride structure with phenyl groups through supramolecular preorganization.

On the way to carbon nitride

Russian Chemical Reviews, 1997
The available data on the problem of hypothetical crystalline carbon nitride are considered. These involve the crystal structure, the nature of chemical bonding, and physical properties of carbon nitride of which the most interesting is its predicted high hardness comparable with that of diamond. The experiments aimed at synthesising carbon nitride are

SYNTHESIS OF CARBON NITRIDE

International Journal of Modern Physics B, 1995
In 1990, Liu and Cohen presented a pseudopotential study of the structural and electronic properties of β- C 3 N 4, a hypothetical compound. The calculated properties of β- C 3 N 4, including bulk modulus and velocity of sound, were found to be comparable to that of diamond suggesting high values for hardness and for thermal conductivity.

Investigations into carbon nitrides and carbon nitride derivatives

2013
Carbon nitrides and carbon nitride derivatives are promising photocatalysts. The main focus of this thesis is the synthesis and characterization of various carbon nitrides (incompletely condensed melon, carbon nitride doped cesium titanate, ultra-long calcined melon, and OH-melem).

Diamondlike Carbon, Carbon Nitride, and Titanium Nitride Coatings on Metal and Polymer Substrates

MRS Proceedings, 1998
AbstractWe have deposited diamondlike carbon, carbon nitride, and titanium nitride biocompatible coatings using pulsed laser deposition and magnetron sputtering on metallic (cobalt-chromium and titanium- 6% aluminum- 4% vanadium) and polymeric (high-density polyethylene) substrates commonly used in human prosthetic devices.

Stability of Small Carbon-Nitride Heterofullerenes

Physical Review Letters, 2003
Carbon nitride nanostructures have been produced by the arc-discharge technique and analyzed by mass spectrometry. A series of structured peaks in the region of masses from 480 up to 600 suggests the existence of heterofullerenes C(n-x)Nx(40 < or = n < or = 50).

Carbon Nitrides: A Promising Class of Materials

High Pressure Research, 2002
(Received 14 July 2001; In final form 28 September 2001)Using a thermal decomposition process of an organic precursor (thiosemicarbazide) under an argon flow, a brownorange solid was prepared. Chemical analysis, X-ray diffraction and infrared spectroscopy characterizations revealthe formation of a well-crystallized bidimensional carbon nitride compound ...

Research on carbon nitrides

Progress in Materials Science, 1997
The status of research on carbon nitride compounds is reviewed including exciting recent results. On the basis of the early theoretical predictions by Cohen and co-workers in 1985-1990, covalent carbon nitrides should be as hard as diamond. The high hardness, high wear resistance and low coefficient of friction make it attractive for industrial ...
