Solution-Processable Core-Extended Quinacridone Derivatives with Intact Hydrogen Bonds
摘要:
A highly efficient and feasible condensation followed by annulation synthetic approach was developed to afford a subset of 9-ring-fused quinacridone derivatives on a 10 g scale. Despite the amenable intermolecular hydrogen-bonding ability of these rigid molecules, good solubility in common organic solvents and solution processability into uniformed thin films were achieved. Integrated advantages in the synthesis and properties make these compounds ideal building blocks for high-performance dyes and optoelectronic materials.

fluorophores containingdifferentchromophores with varying conjugation and electron richness at the imidic nitrogen atom are synthesized and characterized. These amine‐functionalized naphthalimides are bipolar in nature and exhibit interesting optical and morphological variations attributable to the nature of the N substituents. Despite the fact that the dyes are structurally different owing to variation

A carbazole functionalized novel class of bipolar ligand and their corresponding β-diketonate Eu(III) complex was designed, synthesized and characterized successfully. The photoluminescence results show that the efficient energy transfer occurs from the ligand to the europium(III) center metal ion, and a narrow band red emission with apt CIE color gamut is observed. TD-DFT calculations were performed
Controlled Energy Transfer from a Ligand to an Eu<sup>III</sup> Ion: A Unique Strategy To Obtain Bright-White-Light Emission and Its Versatile Applications
diphenylamine-functionalized ancillary-ligand-coordinated europium(III) β-diketonate complex showed incomplete photoexcitation energy transfer from a ligand to a EuIII ion. A solvatochromism study led to a balancing of the primary colors to obtain single-molecule white-lightemission. Thermal-sensing analysis of the europiumcomplex was executed. The europiumcomplex, conjugated with a near-UV-light-emitting diode

based bipolar ligand has been designed, synthesised and utilized to make a Eu(TTA)3Phen-Fl-O-CBZ complex. The absorption spectrum of the ligand shows the expected absorption due to the π–π* transition of the aromatic ring and this was verified by theoretical calculation. The PL emission spectra of the complex clearly indicates that the complete energy transfer occurs from ligand to the Eu(III) metal ion
