1-Etyl-3-(3-dimethylaminopropyl)carbodiimide and cetyltrimethylammonium bromide gave an enhancement on chemiluminescence development of polyphenol dendrimer (Luminescence,18,239-242,2003).We estimated the CH-π interaction between polyphenol dendrimer and acetylcholine bromide (Ach) using ^1H-NMR to develop chemiluminecent method based on noncovalent bond. The N-methyl group of Ach shifted to the high magnetic field in the range of 0.02-0.08 ppm. The complex concentration reached maximum in the molar fraction 0.3 from Job's plots analysis. This indicated that a few of complexes formed. From the effect of Ach on the chemiluminescence of polyphenol dendrimer, 50 mM Ach gave 2.4-fold chemiluminescence enhancement.To synthesize fluorescent dendrimers, the first generation fluorescent dendrimers which have 2-Hydroxyquinoxaline(HQ),4-Hydroxycoumarin(HC) and 9-(Hydroxymethyl)anthracene(HA) as core molecules were synthesized. 3,4,5-Tribenzyloxybenzoyl group gave 1.5- and 1.3-fold enhancement on the fluorescence of HQ and HA, respectively. 3,4,5-Trihydroxybenzoyl group gave 3.1-fold enhancement on the fluorescence of HQ.

1-乙基-3-（3-二甲氨基丙基）碳二亚胺和十六烷基三甲基溴化铵对多酚树枝状大分子的化学发光有增强作用（Luminescence，18，239- 242，2003）。在0.02- 0.08ppm范围内，乙酰胆碱的N-甲基向强磁场方向移动。Job 'splots分析表明，络合物浓度在摩尔分数为0.3时达到最大值.这表明有少量的配合物形成。为了合成荧光树枝状大分子，合成了以2-羟基喹喔啉（HQ）、4-羟基香豆素（HC）和9-羟甲基蒽（HA）为核心分子的第一代荧光树枝状大分子。3，4，5-三苄氧基苯甲酰基分别使HQ和HA的荧光增强1.5倍和1.3倍。3，4，5-三羟基苯甲酰基使HQ的荧光增强3.1倍。
