Synthesis of hyperpolarizable biomaterials at molecular level based on pyridinium-chitosan complexes
Potential NLO-phore materials based on chitosan are described for the first time in this study. A series of fluorescent and quaternized pyridinium– chitosan derivatives have been synthesized by reaction of this polymer with easily available tunable pyrylium tetra fluoroborate salts. Among other spectroscopic techniques, 19 F NMR, 13 C CPMAS...
