The invention relates to esters containing aromatic groups as solvents for organic electronic formulations. Specifically, the present invention relates to formulations for the preparation of organic electronic devices (OLEDs) which comprise (A) at least one specific ester solvent containing an aromatic group and (B) at least one organic functional material selected from organic conductors, organicsemiconductors, organic fluorescent compounds, organic phosphorescent compounds, organic light-absorbent compounds, organic light-sensitive compounds, organic photosensitisation agents and other organic photoactive compounds, selected from organometallic complexes of transition metals, rare earth metals, lanthanides andactinides. 本发明涉及一种作为用于有机电子制剂的溶剂的含芳族基团的酯。具体地，本发明涉及一种用于制造有机电子器件(OLED)的制剂，所述制剂包含(A)至少一种含有芳族基团的特定酯溶剂和(B)至少一种选自以下的有机功能材料：有机导体、有机半导体、有机荧光化合物、有机磷光化合物、有机光吸收化合物、有机光敏化合物、有机光敏化剂和其它的有机光活性化合物，所述其它的有机光活性化合物选自过渡金属、稀土金属、镧系元素和锕系元素的有机金属络合物。
