Bu çalışmada, daha önce tarafımızca sentezlenen P(DEAMSt)L1 homopolimeri ligand olarak kullanılıp Zn(II) iyonu ile metal kompleksi hazırlandı. Homopolimerin Zn(II) metal iyonu ile yaptığı P(DEAMSt)L1-Zn kompleksi bilinen organik çözücülerde çözünmediğinden karakterizasyonda sadece FT-IR tekniği kullanıldı, element analiz ile kompleksteki C, H, N % değerleri belirlenip ampirik formülleri oluşturuldu. SEM görüntüsü alınarak morfolojik yapısı tayin edildi. Metal kompleksin TGA’sı alınarak termal davranışları incelendi. Elde edilen sonuçlar biribiriyle kıyaslandı. Polimer-metal kompleksin impedans analizör tekniğiyle dielektriksel davranışları incelendi. Dielektrik sabiti ’), dielektrik kayıp faktörü (’’), elektrik iletkenliği () gibi özellikleri frekans ve sıcaklığın bir fonksiyonu olarak incelenip, bulunan sonuçlar birbirleriyle kıyaslandı. İletkenlik ölçümlerinden faydalanılarak ln()´ya karşılık 1000/T grafikleri çizilip elde edilen doğrunun eğiminden elektrik iletimiyle alakalı aktivasyon enerjisi (Ea) hesaplandı.
