چکیده

نانو ساختارهای پلیمر سوپرامولکولی ZnBPDH2On 1، H2BPD ´1و1-بی فنیل-´2و2-دی کربوکسیلیک اسید به وسیله‌ی فرایند سونوشیمی سنتز گردید. تبدیل حالت-جامد نانوساختارهای ترکیب 1 به نانورشته های پلیمر کوئوردیناسیونی Ag2BPDn 2 از طریق واکنش تعویض کاتیون ترکیب 1 با AgNO3مورد بررسی قرار گرفت. آنالیز های پراش پرتو ایکس پودری PXRD و آنالیزهای وزن سنجی حرارتی و تفاضل حرارتی TG-DTA، نشان داد که این تبدیل برگشت ناپذیر است. بررسی نتایج گزارش شده از ساختار بلوری این دو ترکیب نشان می دهد که در طی این فرایند، فضای کوئوردیناسیونی ZnO4 در 1 به AgO3Ag2˙˙˙C6 در 2 تبدیل شده و بدین ترتیب طی این واکنش مکانوشیمیایی حالت جامد یک ترکیب آلی-فلزی سنتز گردید.

چکیده [English]

Nanostructures of ZnBPDH2On 1, H2BPD 1,1´-biphenyl-2,2´-dicarboxylic acid supramolecular polymer were synthesized by the sonochemical process. The solid-state conversion of compound 1 nanostructures to nanofibers of Ag2BPDn 2 coordination polymer was investigated by cation exchange reaction of compound 1 with AgNO3. X-ray diffraction XRD analyzes and thermogravimetric and differential thermal analyses TG-DTA have shown that this conversion is irreversible. Consideration the crystal structure of these two compounds, which were reported previously, shows that during this process, the ZnO4 coordination sphere in 1 changed to AgO3Ag2˙˙˙C6 in 2, thus an organometallic compound was synthesized during this solid-state mechanochemical reaction.
