Electroluminescence properties of a non-conjugated polymer poly[2,5-benzoxazolediyl[2,2,2-trifluoro-1-(trifluoromethyl)-ethylidene]-5,2-benzoxazolediyl[2,5-bis(decyloxy)-1,4-phenylene]] (6FPBO-OD)

Synthesis of Light-Emitting Conjugated Polymers for Applications in Electroluminescent Devices

“…2103 Both single-layer devices and double-layer devices using PVK as a hole-transporting layer show blue-white EL with emission maxima around 2.6 eV (480 nm) and 2.2. eV (565 nm), with an efficiency of 0.86% for the double-layer devices. 2104 Copolymers 1074 with naphthalimide chromophores, which are made by a polycondensation route, are reported to show green PL and EL (λ max ) ca. 530 nm).…”

Poly(phenylene vinylene)‐based copolymers containing 3,7‐phenothiazylene and 2,6‐pyridylene chromophores: Fluorescence sensors for acids, metal ions, and oxidation

“…Similarly, the PL peaks of P3 appear at 526 nm in THF and at 555 nm in the film state. However, a shoulder occurs at 610 nm in the film state, which can be explained in terms of the fluorescence excimer and intramolecular charge transfer 29, 30. Moreover, in the film state, the wavelengths of the PL maxima are much longer than those of the absorption maxima, and the Stokes shift can be determined to be 96, 118, and 128 nm for P1 , P2 , and P3 , respectively.…”

Strongly Fluorescent and Thermally Stable Functional Polybenzoxazole Film: Excited-State Intramolecular Proton Transfer and Chemically Amplified Photopatterning

“…Because of the rigid molecular structure and consequent insolubility in organic solvents, however, fabrication and patterning of fine PBO films are seriously limited and remain as an important challenge. In one approach, bulky alkyl groups , or flexible linkages , are introduced into the main chain or side chain of PBO to improve their solubility, which inevitably sacrifices original thermal stability and functional properties of the parent PBO. As a different and more acceptable approach, tert -butyloxy carbonate ( t -BOC) blocking and relevant photopatterning have been successfully employed for the fabrication of linear and hyperbranched PBO films, respectively.…”
