Relevant academic research and scientific papers

Organic compound containing condensed ring structure and organic electroluminescent device

The invention provides an organic compound containing a condensed ring structure as shown in a formula I which is described in the specification. The invention also provides an application of the organic compound in an electroluminescent device. Compared with organic compounds in the prior art, the organic compound containing the condensed ring structure has a narrower half-peak width of an emission peak, so that the organic compound has excellent color purity; when the organic compound containing the condensed ring structure is applied to an AMOLED top emission screen body, higher luminous efficiency can be achieved, and an organic light-emitting device can have lower driving voltage and longer service lifetime.

Cylopentacepyrylene, Cyclopentacepyrylene and Cyclopentacepyrylene: Novel C20H10 Cyclopenta-fused Polycyclic Aromatic Hydrocarbons

Flash vacuum thermolysis of 1,8- (2a), 1,6- (2b) and 1,3-bis(1-chloroethenyl)pyrene (2c) gives the novel C20H10 cyclopenta-fused Polycyclic Aromatic Hydrocarbons (CP-PAHs) cyclopent- (1a), cyclopent- (1b) and cyclopentacepyrylene (1c), respectively; bis(cyclopenta-fusion) topology has a profound influence on their properties.
