1H-NMR, 13C-NMR spectroscopy. Absorbance and emission spectrum of the TMPN was studied in different solvent provide that TMPN is good absorbent and emission red shift in absorbance and emission spectra as polarity of the solvents increase. Photophysical properties including, oscillator strength, extinction coefficient, transition dipole moment, stokes shift and fluorescence quantum yield were investigated
通过Knoevenagel缩合反应合成了2,4,5-
三甲氧基亚苄基
丙烷(
TMPN)。
TMPN的结构通过元素分析和EI-MS,FT-IR,1 H-NMR,13证实C-NMR光谱。研究了
TMPN在不同溶剂中的吸收光谱和发射光谱,条件是
TMPN是良好的吸收剂,随着溶剂极性的增加,发射光谱在吸收光谱和发射光谱中发生红移。为了研究
TMPN的理化特性,研究了光物理性质,包括振荡器强度,消光系数,跃迁偶极矩,斯托克斯位移和荧光量子产率。
染料在不同的胶束中溶解,可用作确定
SDS和CTAB的临界胶束浓度(
CMC)的探针。
