The electroluminescence of organic materials
This article provides a review about electroluminescence from organic materials and deals in detail with organic light-emitting diodes (OLEDs), light-emitting electro-chemical cells (LECs) andExpand
Synthesis, characterization, and electrogenerated chemiluminescence of phenyl-substituted, phenyl-annulated, and spirofluorenyl-bridged oligothiophenes
To overcome the insolubility of higher oligothiophenes and simultaneously to enhance their processability with respect to an application in molecularly doped organic light-emitting devices (OLEDs) weExpand
Synthesis and Characterization of Mixed Oligoheterocycles Based on End‐capped Oligothiophenes
The systematic modification of the central heterocycle of the parent end-capped quinquethiophene EC5T 1 by the introduction of electronegative heteroatoms led to the novel oligoheterocycles 2–6. TheExpand
Interconversion of Nitrenes, Carbenes, and Nitrile Ylides by Ring Expansion, Ring Opening, Ring Contraction, and Ring Closure: 3-Quinolylnitrene, 2-Quinoxalylcarbene, and 3-Quinolylcarbene
Photolysis of 3-azidoquinoline 6 in an Ar matrix generates 3-quinolylnitrene 7, which is characterized by its electron spin resonance (ESR), UV, and IR spectra in Ar matrices. Nitrene 7 undergoesExpand
Linear ketenimines. Variable structures of C,C-dicyanoketenimines and C,C-bis-sulfonylketenimines.
TLDR
Experiments and calculations agree that a single CN substituent as in 13 is not enough to enforce linearity, and sulfonyl groups are less effective that cyano groups in causing linearity; this is also true of N-acyl substituents. Expand
Structure–property relationships in functional conjugated oligomers
Relationships between the structure of de®ned a-conjugated oligothiophenes and their electronic properties were examined. Compared to the parent series of `end-capped' oligothiophenes, the synthesisExpand
Matrix-IR spectroscopic investigations of the thermolysis and photolysis of diazoamides.
TLDR
Flash vacuum thermolysis of diazoamides 1a-d, in which reactions of excited states are excluded, gives rise to clean C-H insertion with only minor Wolff rearrangement to ketenes. Expand
Ketenes and mesoions. Interconversion of mesoionic pyridopyrimidinium olates and pyridopyrimidinones. (2-Pyridyl)iminopropadienone. Part 2
Mesoionic pyrido[1,2-a]pyrimidinium olates 9 undergo rearrangement to the lower-energy pyridopyrimidinones 7 in solution at ordinary temperatures (t1/2 ≈ 51 min at 75 °C), formally via theExpand
