本論文主要欲藉聚甲基丙烯酸甲酯(poly(methyl methacrylate))與笓羧酸(1-pyrenecarboxylic acid)間之氫鍵作用來產生單一發光基團，由螢光光譜儀(PL)的結果顯示，使用不同的溶劑，所產生之激發雙體(excimer)強度也有所不同。四氫

In this paper, we discuss the effect of the hydrogen-bonding on the photoluminescent(PL) properties of 1-pyrenecarboxylic acid (PCA)/
poly(methyl methacrylate) (PMMA). Isolated fluorophore can be obtained when PCA molecules were blended and septrated by PMMA, i. e. excimer emission can be more efficiently prevented. With the use of non-solvent, toluene, in the preparation step, excimer emission of PCA can be more effeiciently prevented as compared to the good solvent, tetrahydrofuran(THF). With a high PMMA/PCA ratio of 1000/1, emission spectra show no sign of excimer formation. Intermolecular hydrogen bonding between PMMA and PCA helps to prevent the excimer formation.
Solvents used in the preparative state play important role on the final PL properties of the solid film. In the blend, partial carbonyl groups in PMMA band with carboxylic acid group in PCA, this causes the appearance of a stretching band at
1718 cm-1 in infrared spectroscopy. The hydrogen-bond interactions help to the prevention of excimer formation in the PMMA/PCA blending systems.
