Usage

General Description

2,7-Dibromo-9-phenyl-9H-fluoren-9-ol is a highly specific chemical compound categorized under the class of fluorenes. Fluorene, the core structure, is a polycyclic aromatic hydrocarbon typically used in organic chemistry as a precursor to other specialized compounds. Regarding the chemical composition, this substance has two bromine atoms (Dibromo), a phenyl group (an aromatic ring of 6 carbon atoms), and a hydroxyl group (OH), all attached to the fluorene base. The compound does not naturally occur in the environment and is instead synthesized in laboratories for specific application in scientific research or industrial uses. Information about this chemical's specific properties, health effects, or toxicity is often specialized and should be explored in dedicated scientific literature.

One-step preparation of novel conjugated porous polymer with tubular structure

A shape-persistent dendritic molecule, tris(4-(2,7-dibromo-9-phenyl-9- fluoren-9-yl)phenyl)amine (TF-6Br), has been readily synthesized in high yield through a concise Friedel-Crafts reaction from triphenylamine and 2,7-dibromo(9-phenyl-fluoren-9-ol). It

Photophysical properties and optical power limiting ability of Pt(II) polyynes bearing fluorene-type ligands with ethynyl units at different positions

Two series of Pt(II) polyynes bearing fluorene-type ligands with ethynyl units at different positions have been synthesized. In the absorption spectra, the Pt(II) polyynes bearing fluorene-type ligands with ethynyl units at 3,6-position have blue-shift with respect to the corresponding analogs bearing fluorene-type ligands with ethynyl units at 2,7-position, showing better transparency in the visible light region. Moreover, the Pt(II) polyynes bearing fluorene-type ligands with ethynyl units at 3,6-position show stronger triplet emission than corresponding analogs bearing fluorene-type ligands with ethynyl units at 2,7-position in the photoluminescent (PL) spectra. Furthermore, these Pt(II) polyynes were applied to optical power limiting (OPL) field. The Pt(II) polyynes bearing fluorene-type ligands with ethynyl units at 2,7-position show better OPL performance than the corresponding analogs with fluorene-type ligands of ethynyl units at 3,6-position. Therefore, changing the position of the ethynyl units in fluorene-type ligands can not only effectively control the photophysical properties of the Pt(II) polyynes, but also has an important effect on their OPL ability.

Bigger and Brighter Fluorenes: Facile π-Expansion, Brilliant Emission and Sensing of Nitroaromatics

π-Expanded butterfly-like 2D fluorenes and 3D spirobifluorenes 1–5 were synthesized via a DDQ-mediated oxidative cyclization strategy with a high regioselectivity. Through structural modification via π-expansion, it was possible to achieve near-ultraviolet absorption, bright-blue emission, very high near-unity fluorescence quantum yields in solution as well as in film states, and deep-lying HOMO energy levels with excellent thermal stabilities. Furthermore, these electron-rich compounds displayed a notable behavior towards sensing of nitroaromatic explosives, such as picric acid, up to a detection limit of 0.2 ppb.
