摘要: Abstract Biocompatible glutaraldehyde-cross-linked chitosan with new red fluorescence were prepared for the first time and shaped into nanoparticles via inverse-microemulsion method. They could luminesce at ca. 670 nm either as powders or in real gelling solutions suspensions, having a lifetime of 1.353 ns quantum yield 0.08 solution 0.01 solid state. The new-formed pyridinium structures intramolecular charge transfer effect are considered to be responsible emission, which have been proved by FTIR, 13 C NMR, some calculation using Gaussian 09, respectively. Strikingly, they quite inert anti-photobleaching, only
