| یک کمپلکس آلی قلع (IV) جدید، {[(C15H9O2)(OMe)2(Me2Sn)4O2]}، با خواص نوری بالا سنتز شد و به وسیله تکنیک های شناسایی 1H, 119Sn NMR و IR ,UVو آنالیز عنصری مورد شناسایی قرار گرفت. لازم به ذکر است که جهت تهیه این کمپلکس از لیگاند آنتراسن-9- کربوکسیلیک اسید با سیستم π- مزدوج بالا با خواص نوری مورد قبول استفاده شد. ساختار بلوری این ترکیب به وسیله اشعه Xتعیین شد. نتایج حاصل از اطلاعات طیف سنجی و آنالیز ساختاری نشان داد که این ترکیب یک کمپلکس چهار هسته ای، یک دی مر با تقارن مرکزی، است که در سیستم تری کلینیک با گروه فضایی p_1^- کریستاله شده است. پایداری گرمایی کمپلکس تهیه شده به وسیله روش وزن سنجی حرارتی (TGA) مورد بررسی قرار گرفت. خواص جذبی و نشر نوری کمپلکس در حالت جامد در دمای اتاق مورد بررسی قرارگرفت. نتایج این بررسی‌ها نشان داد که این ترکیب شرایط لازم جهت استفاده از آن به عنوان پیش ماده در ساخت ادوات نوری را دارا می‌باشد. دیودهایی از کمپلکس و لیگاند آنتراسن-9-کربوکسیلیک اسید تهیه شد و بررسی خواص الکتریکالی آنها نشان داد که دیود متشکل ازکمپلس بازدهی نوری و چگالی جریان بالاتری نسبت به دیود حاصل از لیگاند دارد. همچنین مقایسه رنگ دیودها نشان داد که اتصال فلز به لیگاند منجر به تغییر رنگ دیود نور گسیل آلی(OLED) می‌گردد. | ||

| چکیده [English] | ||
| A novel diorganotin(IV) complex, [(SnMe2)2(C15H9O2)(OCH3)(O)]2, with high optical properties was synthesized by an efficient method and fully characterized by elemental analysis and 1H, 119Sn NMR, IR and UV spectroscopies. It should be noted that the anthracene-9-carboxylic acid with high conjugated π-system and acceptable optical properties was utilized as a ligand for the preparation of this complex. The crystal structure of prepared complex was determined by single crystal X-ray diffraction. Crystal structure analysis of prepared compound displays the attendance of a tetranuclear, centrosymmetric dimeric, complex that crystallizes in the triclinic system with the space group of p_1^-. Thermogravimetric analysis (TGA) has been used for the investigation of the thermal behavior of prepared complex. The absorption and photoluminescence properties of the complex were investigated in solid state at room temperature. The investigation of the optical properties of complex shows that this complex can be as a good fluorescent material in the preparation of luminescence devices like light-emitting diodes. The metal complex significantly increased the optical efficiency and current density of the diode. Also, by adding metal to the ligand, the emission wavelength of the organic light emitting diode (OLED) was changed. | ||
