Flexibility of Poly(alkyl methacrylate)s Characterized by Their Persistence Length Determined through Pyrene Excimer Formation.

ABSTRACT: A series of poly(alkyl methacrylate)s and poly(oligo(ethylene glycol) methyl ether methacrylate)s labeled with 1-pyrenebutanol were referred to as the PyC₄-PC_nMA samples with n = 1, 4, 6, 8, 12, and 18 and the PyC₄-PEG_nMA samples with n = 0-5, 9, 16, and 19, respectively. Pyrene excimer formation (PEF) upon the encounter between an excited and a ground-state pyrenyl labels was employed to determine their persistence length (l_p) in o-xylene. The fluorescence decays of the PyC₄-PC_nMA and PyC₄-PEG_nMA samples were acquired and analyzed with the fluorescence blob model to yield the number (N_blob) of structural units in the volume probed by an excited p
