    1. Chung-Wen Suna , Shun-Chi Chenb and Tai-Shan Fanga* “ Substituent effects on the decomposition of chemiluminescent tricyclic aromatic dioxetanes” Luminescence 2013, Received: 8 March 2013, Revised: 18 June 2013, Accepted: 8 July 2013 Published online in Wiley Online Library (In Print): ABSTRACT:
      Three tricyclic 1,2-dioxetane derivatives, 1a, 2a and 3a were synthesized from their corresponding 1,4-dioxin
      acenaphthylene compounds, 1, 2 and 3, by reaction with singlet-oxygen (1O2) in dichloromethane. Evidence for the formation
      of the dioxetanes 1a, 2a and 3a is provided by the chemiluminescence (CL) that corresponds to the emission from the electronically
      excited diesters 1b*, 2b* and 3b*, which are decomposed thermally from the dioxetanes 1a, 2a and 3a, respectively.
      The highly strained 1,2-dioxetane ring decomposes from a twisted geometry by simultaneous cleavages of the O–O and C–C
      bonds, producing the electronically excited diester that emits CL. It was observed that the CL from compound 2a is
      red-shifted relative to that of compounds 1a and 3a suggesting a higher degree of stabilization for the excited state by
      the electron-donating methoxy group. Also, a study of the solvent effect on fluorescence shows a significant red-shift in
      compound 2b, indicating a more polar excited state. The kinetics of the thermal decomposition of the 1,2-dioxetanes clearly
      demonstrate that the CL characteristics of compound 2a are quite different from those of compounds, 1a and 3a. These
      results are consistent with the proposed intramolecular chemically initiated electron exchange luminescence (CIEEL) mechanism
      which is triggered by the electron-donating group of compound 2a. Copyright © 2013 John Wiley & Sons, Ltd.

    2. CHUNG-WEN SUN1, SHUN-CHI CHEN2* and TAI-SHAN FANG1* “Heavy Atom Effect on the Room Temperature Chemiluminescent  Phosphorescence of the Tricyclic 1,2-Dioxetanes” Asian Journal of Chemistry; (Received: 15th March; Accepted: 20th May 2013) Vol. 25, No. 14 (2013), 0000-0000 (In Print):1,2-Dioxetane tricyclic compound (1a) and 5-halo substituted of 1,2-dioxetane tricyclic compounds (2a, 3a) were synthesized from 1,4-dioxin acenaphthylene compound (1) and 5-halo substituted 1,4-dioxin acenaphthylene compounds (2, 3), by reacting with singletoxygen(1O2) at 238 K and their chemiluminescent efficiency both in fluorescence and phosphorescence was studied while upon heatingto temperatures between 313-353 K in dichloromethane. The chemiluminescent phosphorescence can be detected along with the chemiluminescentfluorescence when compounds (2a, 3a) are decomposed thermally to the corresponding naphthalene diesters (2b, 3b).  Experimental evidences for formation of the dioxetanes 1a, 2a and 3a are the observed chemiluminescence spectra which are consistentwith the photoluminescence spectra of the excited compounds 1b-3b. Temperature-dependent kinetic measurements reveal an increase of room temperature chemiluminescent phosphorescence efficiency from triplet chemiexcitation processes due to the internal heavy atom effect of compound 3a.

    3. Three chemiluminescent systems are reviewed in this thesis. Part one is the chemiluminescence of the
      oxalate system. Analyze the contents of the Cyalume light sticks, and study on the chemiluminescence of the
      phenyl oxalate system whose para-position is substituted by a serious of substituents. Part two is the
      chemiluminescence of the luminol system. Study on the energy transition between luminol and fluorescent
      agents (DPA, DBA, BPEA, and BPEABr). The major focused on in this thesis (Part three) is the
      chemiluminescence of the dioxene system. Study on the ozonization of the 3 fluorescnet compounds
      (naphthalene A, biphenyl B, and anthrathene C), and the properties of the following chemiluminescence. Results
      show the compound A and C which emit the chemiluminescence, but the compound B doesn’t. The compound A
      is oxidized by reaction with singlet-oxygen (1O2) in dichloromethane. Evidence for formation of the dioxetane
      compound is the chemiluminescence spectra that correspond to emission from the electronically excited diester
      compound, the expected products from thermal decomposition of the dioxetane. Reference LinkReference Link Attach FileAttach File Adobe PDF
    4. The photochemical reactions of colchicine and thiocolchicine were studied in this thesis.
      The difference of structure between colchicine(1) and thiocolchicine(5) is that hydroxyl
      functional group(-OH) on the tropolone ring is substituted, one is methoxyl functional
      group(-OCH3), and the other is methylthio functional group(-SCH3). Because of their similar
      structure make the physical and chemical properties similarly, and both they are effective
      treatment for gout drugs. However, the poor resistance to UV light of the tropone which is
      easily photocyclized by irradiation makes them easy to perish. Irradiation of colchicine(1)
      gives mainly two photoproducts: β-lumicolchicine(2) and γ-lumicolchicine(3). Further
      irradiation of β-lumicolchicine(2) gives the photoproduct of α-lumicolchicine(4). Irradiation
      of thiocolchicine(5) gives β-lumithiocolchicine(6) and γ-lumithiocolchicine(7). The chemical
      kinetic of colchicine(1) and thiocolchicine(5) is studied and the ratios (β/γ) of photoproducts
      is analyzed under different polar solvents and irradiative times. The results show that both
      colchicine(1) and thiocolchicine(5) favor the Woodward-Hoffmann electrocyclic reaction.
      Colchicine(1) has higher photochemical reactivity and higher product stereoselectivity with
      the methoxyl functional group(-OCH3) of tropone. Thiocolchicine(5) with the methylthio
      functional group(-SCH3) of tropone has lower photochemical reactivity and lower product
      stereoselectivity. Reference LinkReference Link Attach FileAttach File Adobe PDF

        1. The end of cold war in 1990s has been characterized by widespread discussions about the need for the creativity and the innovation. Concurrent with international efforts to reform science and technology education, Taiwan has properly embarked on its own efforts to change the nature of creativity and innovation education. This paper comments on these efforts from the precise and accuracy perspectives of nature of the energy (zero change, conservation) and entropy (one lively exist, motivation).  It portrays science and technology education reform in Taiwan in the context of global changes that are occurring throughout much of the world and in the context of institutional changes occurring within Taiwan. The article attempts to elucidate unique assets, problems, and opportunities facing creativity and innovation reform in Taiwan. The need to incorporate special attention to Taiwan’s rich man-power resources, local technologies and technology tools, Chinese-Western mixed culture contributions to technology and to perceptions of the natural world, strength in vocational along with life-long career education, and cultural traditions’ reflection is briefly examined. The paper also briefly discusses some concerns that may need to be evaluated such as the role of examination and competition in schools and the society.
