The ultraviolet (UV) absorption spectra of the supermolecular system involving silver nanoparticles-substituted N-(phenyl-ethylene)-anilines were investigated. Silver nanoparticles (AgNPs) and 77 kinds of substituted N-(phenyl-ethylene)-anilines ZArC (Me)NArY (ZPEAY, including 40 compounds 2-H-XPEAY without ortho-hydroxyl and 37 compounds 2-OH-XPEAY with ortho-hydroxyl) were prepared. The size of AgNPs was measured with transmission electron microscopy. To study the effect of substituents X and Y on the UV spectra of the supermolecular system of AgNPs-ZPEAY, the authors measured the UV absorption spectra of AgNPs, ZPEAY, and AgNPs-ZPEAY solutions. The experimental results show that (a) the size of AgNPs increases in AgNPs-ZPEAY solution compared with that in AgNPs solution, due to the absorption of ZPEAY molecules on the surface of AgNPs; (b) the UV absorption wavelength of ZPEAY changes in AgNPs-ZPEAY solution and there is a limitation for the wavelength shift (lambda (WSL)) between ZPEAY and AgNPs-ZPEAY system; (c) there is a quantitative correlation between the wavenumber Delta nu (WSL) of lambda (WSL) and the substituent constants (Hammett constant sigma and excited-state substituent constant sigma CCex) of substituents X and Y; (d) the intramolecular hydrogen bonding in 2-OH-XPEAY makes the Delta nu (WSL) a red shift in AgNPs-ZPEAY system.
