Abstract: Abstract Dilute acid pretreatment of biomass decomposes hemicelluloses but cannot effectively remove lignin. Here we investigate the adding of add five nucleophilic derivatives including 2-naphthol, 6-hydroxy-2-naphthoic acid (6H2NA), 2-hydroxy-1-naphthoic acid (2H1NA), 6-hydroxy-1-naphthoic acid (6H1NA), and… read more here.

DOI: 10.1039/d2ra03046b
Abstract: Herein, bromo-naphthol derivatives were synthesized to investigate the influence on their phosphorescence emission efficiency resulting from different binding models with cyclodextrins. And the results indicated that α-cyclodextrin could result in the highest phosphorescence emission efficiency,… read more here.
