Over a number of years work in our laboratory has been exploring the use of cellulose nanocrystals as scaffolds for the creation of novel nanomaterials with unique and stimuli responsive characteristics. In this communication we will report on our systematic efforts aimed at functionalizing cellulose nanocrystals by using both grafting from and grafting to approaches. The reactive hydroxyl groups on cellulosic surfaces lay ground for successful grafting reactions. Therefore, in connection to our grafting experiments the amount of accessible hydroxyl groups in cellulosic surfaces was studied by using recently developed phosphitylation method followed by 31P NMR analysis.
