Abstract

A new series of boron complexes consisting of pyridine‐pyrazole ligands has been designed, synthesized and evaluated for its Raman activity using solid‐state Raman spectroscopy. The detailed surface‐enhanced Raman scattering (SERS) study of selected dye 2‐(3‐(pyridin‐4‐yl)‐1H‐pyrazol‐5‐yl) pyridine (P4) on gold nanoparticles (AuNPs) of size 40 nm revealed that it can detect as small as the nanomole level with signal quality that is superior to structurally similar commercially available reporter molecules (RMs), rendering it a suitable RM for sensitive SERS nanotags.
