Siklomatriks yapılı net-poli(siklotetrafosfazen-ko-tiramin) mikroküreler çöktürme polimerizasyonu ile tek adımda sentezlenmiştir. Elde dilen mikrokürelerin karakterizasyonu SEM, EDX, FTIR, XRD ve DLS teknikleri ile yapılmıştır. Ayrıca mikrokürelerin UV ve floresans özellikleri de incelenmiş olup, mikrokürelerin 239 nm’de maksimum absorbans yaptığı belirlenmiştir. Tiramin ve mikrokürelerin katı hal floresans özellikleri, 254 nm dalga boyunda uyarılarak incelenmiştir. Tiramin çok zayıf emisyon yaparken, mikroküreler 308 nm’de şiddetli emisyon göstermiştir. Elde edilen sonuçlar, sentezlenen polifosfazen mikrokürelerin sensör, biyolojik kataliz ve görüntüleme gibi floresans uygulamalar için yüksek potansiyele sahip olduğunu göstermektedir.
Cyclomatrics made net-poli (cyclotethrafosphagen-co-tiramine) microcurns are synthesized in one step by collapse polymerization. The characterization of the desired microcuries is made with the techniques SEM, EDX, FTIR, XRD and DLS. The UV and fluorescence properties of microorganisms have also been studied, and the maximum absorption of microorganisms at 239 nm has been determined. The firm state flowering characteristics of tiramines and microcuries have been studied by warning at 254 nm wave length. Though tiramine makes very low emissions, microwaves showed severe emissions at 308 nm. The results show that synthesized polyphosphane microcuries have a high potential for fluorescence applications such as sensors, biological catalysts and imaging.
Cyclomatrix structured net-poly(cyclotetraphosphazene-co-tyramine) microspheres were synthesized by single step precipitation polymerization. The characterization of obtained microspheres were performed by SEM, EDX, FTIR, XRD and DLS techniques. Besides, UV and fluorescence properties of microspheres were researched and it was determined that microspheres have been shown maximum absorption at 239 nm. It was investigated the fluorescence characteristics of tyramine and microspheres as solid state, using 254 nm as the excitation wavelength. The microspheres showed a strong emission peak at 308 nm, whereas the emission peak of the tyramine was very weak. The obtained results show that the synthesized polyphosphazene microspheres have a high potential for fluorescent sensor, biological catalysis and imaging applications etc.
