1,10-Phenanthroline, a commonly used spectroscopic reagent,
plays an indispensible dual role in the deposition of CdS on the VA-CNT surface.
1,10-Phenanthroline is a highly conjugated molecule
consisting of three fused six-member rings with two nitrogendoped
heterocycle at the wings, so that this molecule itself is prone
to attach on CNTs via p-stacking and hydrophobic interactions
