Plasmon resonance-enhanced circularly polarized luminescence of self-assembled meso-tetrakis(4-sulfonatophenyl)porphyrin–surfactant complexes in interaction with Ag nanoparticles†
Abstract
The chiroptical properties of an anionic meso-tetrakis(4-sulfonatophenyl)porphyrin (TPPS) complexed with cationic surfactants were enhanced by interaction with silver nanoparticles (AgNPs) in acidic solution. Improvement in chiroptical properties was revealed by circular dichroism (CD) and circularly polarized luminescence (CPL), with |gabs| and |glum| values reaching 0.05 and 0.001 at 303 K, respectively.
