1. Electroluminescent materials
Generally speaking, EL electroluminescent materials in the art (low-molecular-weight molecules or polymers) attempt to combine :
good solid-state photoluminescence performance;
good charge transport properties (high carrier mobility).
In the case of low-mass molecules, high photoluminescence efficiencies can be achieved in the solid state by doping the emitting layers (see [ ]). Polymers, on the other hand, are generally not doped, although some can achieve high fluorescence efficiencies. For example, poly[2-(dimethyloctylsilyl)-1,4-phenylenevinylene] (DMOS-PPV) and poly[9,9-bis(methoxyethoxyethyl)fluorene] (BDOH-PF) (figure 1 ) have η ...

A distinction must be made between evaporated molecules and polymers.
Evaporated molecules
A number of evaporated molecules are included in classic fine chemicals catalogs (Aldrich, Lancaster, etc.).
Other molecules are sold specifically by certain companies, such as :
