    Host-Guest Interaction of calix[4]arene derivatives with MetforminAC
    (Central University of Punjab, 2018) Gupta, Harshita; BabuJ. Nagendra
    Calix[4]arene was lower rim functionalized to furnish receptor 2-3 and 4-6, containing propyl and cyanomethoxy moieties, respectively. The receptors were characterized by FTIR, 1H and EI-MS. UV-visible studies were performed with receptor 2-6 cone (1'10-4M) upon addition of metformin (1'10-5 - 1'10-3M). Upon addition of metformin the UV-Visible absorption showed a hyperchromic shift.The 1:1 Host-Guest complexation studied by Benesi-Hildebrand equation showed a stability constant in the range 2'104 -10'104 M-1 .

    Polynuclear Aromatic Hydrocarbon (PAH) Inclusion in Lower Rim Substituted Calix[4]arene
    (Central University of Punjab, 2018) Ram, Mange; Babu, J. Nagendra
    Calix[4]arene was lower rim functionalized to furnish receptor 2-3 and 4-6, containing propyl and cynomethoxy moieties respectively. The receptors were characterized by FTIR, EI-MS, 1H and 13C NMR. UV-visible studies were performed with receptor 2-5 cone and 6th 1-3,aternate. (2x10-4) upon addition of Naphthalene, Anthracene and Pyrene. Upon addition of Naphthalene, Anthracene and Pyrene the UV-visible absorption showed hyperchromic shift. The one-to-one Host-Guest complexation studied by Benesi-Hildebrand equation showed stability constant in the range 2-10x104 M-1 .
