Ushbu maqolada tarkibida azot, oltingugurt va fosfor donor atomlari mavjud bo‘lgan ligandlar asosida bir inchi qator 3dmetallari kompleks birikmalarini silikagel matritsasiga nokovalent immobilizatsiya qilishning ilmiymetodik asoslari yoritilgan. Tadqiqotning asosiy g‘oyasi metalligand kompleksining koordinatsion tabiatini saqlagan holda, uni g‘ovak SiO2 yuzasida dispers holatda ushlab turishdan iborat. Silikagelning sirt silanol guruhlari, g‘ovak tuzilishi va yuqori solishtirma sirt maydoni komplekslarni fizik adsorbsiya, vodorod bog‘i, elektrostatik hamda donorakseptor o‘zaro ta’sirlari orqali immobilizatsiya qilish uchun qulay muhit yaratadi. N, S va Pdonor markazlarining elektron donorlik xususiyatlari Fe, Co, Ni, Cu va Zn kabi 3dmetall ionlari bilan kom pleks hosil bo‘lishini belgilaydi. Maqolada ligandni tanlash, kompleks hosil qilish, silikagelni faollashtirish, nokovalent immobilizatsiya, yuvish va quritish bosqichlari ketmaketligi ishlab chiqilgan. Hosil bo‘ladigan materiallarni FTIR, UVVis/ Diffuse Reflectance, XRD, SEMEDS, BET va termogravimetrik tahlil yordamida tavsiflash mezonlari asoslangan. Taklif etilayotgan yondashuv geterogen kataliz, sorbsiya va qayta foydalaniladigan metallokompleks materiallar yaratish uchun istiqbolli ekani ko‘rsatilgan.Ключевые слова
