Abstract
Maqolada glitsirrizin kislotasining monoammoniyli tuzi (GKMAT) bilan 5-xlorindol-3-sirka kislotasining (5-ClI-3-SK) 2:1, 4:1 va 8:1 molyar nisbatlardagi supramolekulyar komplekslarining UB - va IQ-spektroskopiya usullari yordamida tavsiflanishi bayon etildi. Spektral ma’lumotlar GKMAT va 5-xlorindol-3-sirka kislotasi (5- ClI-3-SK) o‘rtasida komplekslanish jarayoni sodir bo‘lganligini ko‘rsatdi. Kompleks hosil bo‘lishida –OH, –NH va –C=O guruhlari ishtirokidagi vodorod bog‘lari hamda boshqa nokovalent o‘zaro ta’sirlar muhim rol o‘ynashi aniqlandi. Komplekslarning unumi 95, 93 va 92% ni tashkil etdi. Izomolyar seriyalar usuli asosida 2:1 kompleksning shartli barqarorlik konstantasi Ks = 5,0×10⁶ M⁻¹ deb baholandi. 303 K haroratda Gibbs erkin energiyasi ΔG ≈ −38,8 kJ/mol ni tashkil etdi. Olingan natijalar GKMAT va 5-ClI-3-SK o‘rtasida barqaror supramolekulyar komplekslar hosil bo‘lganligini tasdiqlaydi.References
