- Abstract
- We synthesized 1-(2-amino-phenyl) naphthalene-2-ylamine (APNA) and inserted them into the inside SWNTs. Besides measuring IR, Raman, and absorption spectra of the APNA encapsulated SWNTs, photoluminescence spectra of APNA molecule after encapsulation were obtained for the first time. Analysis of those spectra revealed that the APNA withdrew electrons from the SWNT, and also supplied the information about the ground and excited-geometry after encapsulation.
